French Drain Installation can be tricky sometimes.  Recently we installed a French Drain in Norman with very little “Fall”.  This means that the “Intake” For the Drainage System is close to the same level as the “Exit.”  Simply Put, it is hard to make a Drain work if it isn’t ” Down Hill,” to where the water is going.

New French Drain

French Drain with very little fall

This was the Situation for the French Drain we installed last week in Norman.  The standing water was in the back yard.  There was only one direction that we could take the unwanted water to drain away.  In this case it was only slightly down hill.  The French Drain was installed at a shallow level in the back yard.  The solid drain pipe that was attached ran from the back yard, along the side of the house to a curb outlet at the street.

As the trench for the Drain Pipe was dug, it had to start shallow and slowly get slightly deeper as it approached the street.  This was an absolute Precision Job.  The trench could not be even an inch too deep or too shallow along its course.

At the street, a “Pop-Up” Emitter could not be used.  It would cause the water to stop flowing.  Two Install a Pop-up Emitter at the Exit of any Drainage System,  There must be at least 6 inches of “Fall” from the Drain to the Exit.

In Our Case, we only had 3 inches of fall to work with.

The solution was to Cut the curb and Install a Curb Outlet.

This process involves cutting the Curb with a concrete saw and placing a rectangular Curb outlet in the empty space.  We then put acrylic concrete around the outlet to make it look nice.

The fact that the outlet is square or rectangular is very important.

Many times I look at Round Curb outlets installed by my competitors and just shake my head!  This is a mistake.  Round Curb outlets are bad when the Drainage System is at Max Capacity and the pipe is completely full.  Air needs to be able to get into the pipe at the curb to ensure that the Drainage System can work at its Max.

The Drain will work with a Round Outlet, Just not very well.

Have you ever tried to Pour liquid out of a Jug or 2 liter bottle holding it completely upside down?

It Drains and Stops and Starts as the liquid comes out.  “It Chugs” and struggles to get air up inside the hole.  It doesn’t work very well.

A Square Outlet allows air to constantly flow into the top corners of the Curb Outlet.

As a result, Much more water is moved in the same size pipe.

Recently Oklahoma Drainage and Sprinkler Repair installed a large 6 inch French Drain in Edmond.  The customer had water running under his back porch step and into his basement.  We did a Free Drainage Diagnostic and Estimate.  The French Drain design that we proposed would intercept the surface water and subsurface water that was flowing under the steps.  The French Drain design called for a 6 inch French Drain to be installed above and several feet away from the steps.  It would run around the house parallel to the foundation and about 5 feet to the East.  The French Drain would run past the steps to a point where water must cross the French Drain or run up hill to the steps which in this case was not possible.  Once past the steps, the French Drain would transition to Solid 6 inch Drain Pipe and continue on around the house to the Pop-Up Emitter down hill in the side yard.  Along the way we attached several Gutter Down Spouts into the French Drain.

Oklahoma Drainage and Sprinkler Repair has been diagnosing and solving Drainage Problems since 1993.  Water has the ability to get into places around your home where you really don’t want it to be.  Some drainage problems are easy to solve.  Typically water enters the problem drainage area one way from one source.  The really tricky drainage problems occur when water enters the problem drainage area from multiple directions and from multiple sources.  Sometimes a secondary water source can’t be seen or identified until the primary water problem source is eliminated.

An example of this occurs when water is running into a problem area in an obvious way over the ground where you can see it.

Simple enough.

A drainage system is installed with a surface drain as the “intake” with drainage pipe running to an exit point.  Initially the water drains away and everything looks great.  The next day water is back and is all around the surface drain, but below the edge and it hasn’t rained at all, so no additional water ran over the surface of the ground to flood the area.  The primary water source was solved, ( The surface water run off ) but the secondary water source was not.  Which was sub-surface water, (ground water) running into the area.  A surface drain can’t drain “ground water.”  A French Drain should have initially been installed instead of a Surface Drain.  A French Drain can drain both Surface Water and Ground Water.

Drainage Systems can be made up of one drain or a combination of many drains.  Drainage  problems can be very complex.   Complex Drainage Problems may require a combination of several different types of drains all inter-connected and working together.  Other times the drainage problem may be simple and straight-forward requiring only one drain or several of the same type of drain connected together.

An example of a complex drainage system would be:  A French Drain in the back yard connected to a Surface Drain near a flower bed connected to several gutter downspouts, which are connected to a Channel Drain going across a driveway, which is connected to additional Surface Drain in the front yard, which runs to a Curb Fitting that lets all the water drain out on to the street.

A simple Drainage System might consist of a Surface Drain that is connected to a second Surface Drain which runs to a Pop-up Emitter which lets water drain over the curb and into the street.

An “Exit Point” is the term used for where all the water leaves the Drainage System.  Determining the Exit Point is very critical.  It is one of the first things we do when diagnosing a Drainage Problem.

Drainage Systems can:

1.  Keep water away from foundations — A French Drain is best because it can move Surface Water and Sub-Surface Water (water moving under ground) away from the foundation.  Many times less experienced companies install Surface Drains to keep water away from foundations.  This can be a big mistake.  A Surface Drain can’t move or drain Sub-Surface Water.   Also A Surface Drain often can’t move enough water fast enough and easily becomes overwhelmed during a heavy rain.  A Surface Drain also can’t cover or protect a broad enough area. Surface Drains should be designed in a Drainage System to be located in smaller Drainage Areas moving moderate amounts of water.  Surface Drains look better than French Drains.  If ,”appearance” is more important than Drainage Capacity, Go with the Surface Drain.  Just know what you are getting into and what your expectations should be. One side of a foundation alone,  can be over 100 feet.  A 4 inch or 6 inch French Drain is best when protecting a large area such as a foundation.

2.  Keep water away from small or enclosed areas.  This might be a low area just through a gate on the side of a house, or the low area between a flowerbed and the wall of a house, or standing water on or near a sidewalk or driveway.  These types of Drainage Problems are best served with Surface Drains.  A Surface Drain can move water away from a low area that is relatively small.  This can occur in yards, flowerbeds, sidewalks and driveways.  A Surface Drain is designed to move Surface Water away from a problem area to a predetermined exit point.  Surface Drains are available in many sizes.  How quickly they remove standing water is usually determined by the size of the Drain Pipe that is connected to the Drain.

Simply put, a Drainage System is one or a group of underground Drain Pipes that take water away from a place that has water standing on it or flowing across it.  The water that is in the problem area, can be causing damage or may be inconvenient or both.  (Usually Both)  A simple Drainage System is a Drain for the water to enter, a Drain Pipe to move the water away from the Drain, and an Exit Point for the water to be released out of the Drain Pipe.

Drainage Systems quickly can become more complicated.  Considerations must include:

How does the water get to the problem area?  There may be one or many sources.

Water Sources:

1.  It falls from the sky directly

2.  It flows down hill over the surface (surface water)

3.  It flows underground under the surface (sub-surface water)

4.  It flows from the edge of a roof ( There may be many roofs near the problem area, neighbors etc.)

5.  It flows from a gutter downspout

6.  It flows over the edge of a gutter because the gutter is too small is is clogged

7.  It flows up from the ground (seeps and springs are common in Oklahoma)

8.  It flows from a sprinkler system use ( yours or your neighbors)

9.  It flows from a leaking pipe ( water mains, water meters, water lines, sprinkler pipes, sprinkler valves)

There are other reasons for Drainage Problems, the above reasons are just the most common.

Once the number of water sources is determined, a rough estimate of the amount of water that needs to be drained away on average must be estimated.  This can be simplified down to “SMALL, MEDIUM, OR LARGE AMOUNTS OF WATER TO BE DRAINED AWAY.  You don’t have to be an engineer trying to calculate fluid dynamics.  Experience at diagnosing drainage problems helps however.  How much water needs to be moved will help determine the type and size of the Surface Drain or French Drain that needs to be installed.  It also helps to determine the size of Drain Pipe required for the Drainage System.  A good rule to follow is, “If in doubt, install a larger Drain and Drain Pipe.”  Unused Drainage Capacity is better than property damage caused by a Drain that is overwhelmed by too much water.

For home and small business use typical materials used are:

6 inch, 9 inch, and 12 inch Surface Drains

3 inch, 4 inch, and 6 inch Drain Pipes

3 inch, 4 inch, and 6 inch French Drains

French Drains move more water than Surface Drains —

French Drains move Surface Water and Sub-Surface Water

Surface Drains move Surface Water only

Surface Drains look nicer than French Drains in most cases

Once the type and number of drains is determined and what size Drain Pipe will connect them, an exit point must be selected.  (Where is the Drainage System going to take the water to and release it?)

The Drainage Curb Fitting is installed when the desired exit point for the French Drain will release the Drainage Water into the Street.   The Drainage Curb Fitting is rectangular in shape and made to be installed through the curb.  A small section of Curb is cut out with a concrete saw.  The Section is a few inches wider than the Drainage Curb Fitting.  We then install new concrete around the curb fitting.  Once the concrete has dried, the Drain Pipe coming from a French Drain or Surface Drain is connected to the Drainage Curb fitting and then covered with dirt.

The Drainage Pop-Up Emitter is connected to the end of a Drain Pipe.  It is downhill from a French Drain or a Surface Drain.  It is a small release basin with a green pop-up lid.  When releasing water, it pops up about an inch to release the water from the French Drain or Surface Drain.  When the Storm Water has moved through the Drainage System and out of the Pop-Up Emitter, the green lid closes back to its original closed position.  The emitter is designed to release water out into a yard or down a hill or other desirable Drainage Exit Point where there is no curb.

Recently we installed a large Drainage System in OKC.  It was a 4 inch System using 4 inch ADS French Drain Pipe with Soc and 4 inch ADS Solid Drain Pipe.  The “Intake” of the Drainage System had two parts.  Water from the gutters on the house was fed into the Drainage System.  There were 7 gutter downspouts around the entire house that were connected straight into the Drainage System with Solid Drain Pipe and a Gutter connection.

We Installed a Double Six inch French Drain in Edmond this week.  A Double Six Inch French Drain is two six inch French Drains laid side by side in one very wide and deep trench.  It is designed to move a huge amount of water away from a home.   Our customer had several different drainage problems in their back yard.  After a thunderstorm, water would run under their back fence and into their garage.  The back yard was on a steep hillside and the water would run very fast down the hill and into the garage.

Oklahoma Drainage and Sprinkler Repair installed 2 large six inch French Drains across the water’s path.  This allowed the water to be diverted into the French Drain which then ran through drain pipe to a curb outlet at the street.  Three Gutter Down Spouts were connected into the French Drain.  The French Drain created a protective barrier for the garage.  A 12 inch Surface Drain was also included in the Drainage System.  It was placed up against the driveway and connected with 4 inch Solid drain pipe to the 6 inch French Drain.  Water was completely rerouted away from the home.  A French Drain  and Surface Drain combination in this case was the best solution to this particular drainage problem.

Oklahoma Drainage and Sprinkler Repair  installed a 4 inch French Drain in East Norman this week.  The customer had water standing on the side of his house that was causing foundation damage.  He contracted a Structural Engineer to come out and look at the Drainage Problem and to give him some advise.

The Structural Engineer recommended a French Drain to protect and draw water away from the foundation.  He said that, “he had recommended French Drain Installation to solve similar problems for home owners many times in the past.  The Structural Engineer was confident that it would solve the Drainage Problem.

 

Next, our customer went online and found us by searching under, ” Norman Oklahoma French Drain.”
The Gentleman gave us a call to set up an appointment.  We arrived on the agreed time and provided a ( Free- No Obligation- Drainage Diagnostic and Quote) We came out and looked at his Drainage Problem and designed a Drainage System to solve his, Standing-Water Problem.”  We also recommended a surface drain in a corner where water was coming off a steep part of the roof and overwhelming the gutter.

The customer let us know that he was ready to move forward.  We scheduled the Drainage System Installation for the following week.  When the scheduled day arrived, we installed the Drainage System.  The Drain was made up of a 6 inch French Drain running 30 feet along the East side of the house.  It curved around the corner of the house.  At that point a 12 inch Surface Drain was connected to the French Drain with 4 inch pipe.  The 6 inch French Drain at that point changed to 6 inch Solid Drain Pipe and continued under ground 65 feet to a pop-up emitter at the curb in the front yard near the street.

Edmond Oklahoma has been the location for many French Drain Installations for us in the past several years.  Recently we ripped out an old Surface Drain that was under a deck.  The Surface Drain was too small for the job and did not Protect the Foundation from Standing Water


 The First step was to take out part of the deck along the wall.  Next we took out the Surface Drain and the Three Inch Pipe which was too small.  Digging a trench along the foundation came next.  We had to ensure the, “Fall” to make sure the water would run from left to right. 

 Next a French Drain Liner  needed to be installed.  This was necessary to maintain the integrity of the trench and to keep the French Drain Pipe from filling up with sand and getting clogged over the next few years.  Oklahoma Drainage  then installed 4 inch ADS Perf/Soc French Drain Pipe along the course of the French Drain.  Next we connected the end of the French Drain Pipe to Solid 4 Inch ADS Drain pipe to continue along the trench to the Pop-Up Emitter at the Exit Point.

The French Drain we installed ran across the back yard in two places, then it connected to solid ADS Drain Pipe and Ran to the street where a Curb Outlet was installed.

Installing a curb outlet takes experience and skill.  We cut the curb with a concrete saw.  Water is used with the saw to make better cuts and to keep the concrete dust to a minimum.  The cut in the curb will be at least two inches wider than the curb outlet that will be set in concrete.  This ensures strength and longevity.  When installing the cement we use cement with Acrylic to further ensure the strength of the outlet.  It takes a while for the concrete to cure.  The new concrete will be darker than the surrounding curb for a while but eventually it will match up.

We cut the sod out by hand when installing Solid Drain pipe.  The sod is set to the side while the 4 inch pipe is installed.  Then some of the dirt is placed back on top of the drain pipe and the sod is placed back in its original position.  Some of the dirt is left over that is displaced by the new drain pipe.  That dirt is hauled away. 

Recently Oklahoma Drainage and Sprinkler Repair Installed a French Drain as part of a Drainage System in Mid West City Oklahoma.

Our customer had a back porch Sun Room.  Every time he had a hard rain, Water would run in one door and out the other.  An indoor creek across his Sun Room.

We installed a French Drain in front of the South Door.  It was 26 feet long and ran from a gutter downspout which it was connected to,  in front of the South Door and along the house covering the entire “Low” Area.  Then we connected 4 inch ADS Solid Drain pipe to the French Drain and ran down hill around the corner of the house to the street.

Once the 4 inch solid drain pipe was connected to the French Drain and the two gutter down spouts, a pop-up emitter was installed to release the water at the street.

The next step was to cover the drain pipe with dirt and put the sod back in place on top of the pipe.   There was about 8 wheelbarrows of dirt left over that was displaced by the drain pipe and the French Drain.  The extra dirt was scooped up and hauled away.

While installing the drainage system, it was necessary to move two sprinkler heads that were in the way of the drain pipe installation.  This was no problem.  Installing drainage systems and French drains for folks who have a sprinkler system is very common.  Moving Sprinkler heads or pipes sometimes is necessary.  We always leave the sprinkler system in complete working order and we discuss any changes in the sprinkler system with the customer before we do it to make sure that everyone is on the same page.  In most cases the customer cant tell that we made any changes to the sprinkler system at all.

Before you ever build a Drainage System,  you need to decide where you are going to take the problem water too.   Most residential Drainage Systems release water farther on down the hill, or release it out into the street.  Street release is either over the curb or through the curb.

Previous Blog        Next Blog

It is a good idea to do a little research on the effects and liabilities of releasing water at your home.  What does the city think if you release water through the curb vs over the curb?  What does your downhill neighbor think if you are releasing water into his yard?

Some Drainage System Locations have many options for ” Exits.”  Others have vary few.

Don’t Start a Drainage System if you don’t have a good place for the water to exit!

This is even more important, if your Drainage System needs to be a “Flood Prevention System.”  We talked about this in the previous blogs on Drainage.

A Flood Prevention System may need more than one exit to increase the Drainage Systems Capacity.

 

OK, So you have a good Water Exit Strategy and have identified where the water is going to go.

Lets go back and talk about Pop Up Emitters and Curb Outlets.

A Pop Up emitter is used to release water down a hill or over a curb and into the street.

Pop up emitter and ADS

Pop-Up Emitter before Installation

Water hits the Emitter and fills it until the water pressure lifts the lid and the water drains out.

Good “Fall” or ” Slope” is necessary for a pop up emitter to work properly.  Many times a Drainage Pipe does not run down hill enough for a Drainage System to work well. You need “Slope” for your drain to work.   Water may move very slowly and never lift the lid and it just sits there.

We will talk about having the correct amount of “Fall” or “Slope” in a Drainage System in the next blog.

Curb fittings or outlets is the other way to release water.

Curb Outlet as an Exit Point for a French Drain in Edmond

First off,  For your average DIY Guy.  Installing a Curb outlet may be beyond your skill set or capacity.  If that is the case just place a Pop Up Emitter up against the curb and go on about your business.

That being said, you may still want or need a Curb Outlet set in concrete.

If you are good with concrete and a concrete saw, this option poses no problem.  If this option seems too much for you, it probably is!  Consider sub contracting the curb outlet.  In higher populated areas, finding someone to do “Light” concrete work is relatively easy.  You sill can save money by installing the rest of the Drainage System yourself.

If you are sill going to install the “Curb Outlet,” here are the steps for a “First Timer.”

Step 1  Find a Curb outlet fitting.  They are round on one side where the drain pipe connects and rectangular on the other to fit in the cut out area for the Curb outlet.

Curb outlet fitting

Curb outlet fitting

They are sold in many Drainage Supply Businesses.  You may not find them at “Lowes” or ” Home Depot”.  It varies.  If a Specialized Drain Supply business is not available then use a “Heat and Air” Floor vent as your curb outlet.  They are made of metal in most cases but still will work very well.  I have done this many times.  The floor vent is typically wider and thinner than a standard Curb Outlet Fitting.  Just cut a wider hole in the curb.

Step 2 Watch an instructional safety video on using a concrete saw.

Step 3 Rent or buy a concrete saw.  A used one can be found in pawn shops for about 300$ to 600$.  A New one will run around a Thousand Dollars.

a Rental will run about 50$ to 150$ depending on your area.

Step 4  Find a Curb outlet that matches the size of your Pipe.  If you have a 4 inch Drain pipe then install a 4 inch curb outlet.   Sometimes a Six inch Curb outlet is too big to install in many roadside curbs.  It is too tall in many cases.  In most situations if you want a curb outlet and have a Six inch Drain Pipe, you must install two 4 inch outlets side by side.

If you have the need for a six inch Drain Pipe,  that means you have a lot of water to move.  You don’t want to create a bottle neck at the curb by installing a 4 inch curb fitting as your exit on a Six Inch Drain Pipe.

What you need to do is dig a large hole at the curb so you have room to work.  Next you attach a 6 inch “Y” fitting onto your drain pipe above the curb several feet.  You then install Two Reducer Bushings in both outlets of the “Y” fitting.  Next you attach 4 Inch ADS Drain Pipe to the outlets and run two 4 inch ADS Drain pipes to the Curb.  Now you install two 4 inch curb fittings side by side.

It is very important to use ADS Pipe coming out of the 6 Inch “Y” fitting.  It is Flexible and can be easily bent to fit your application.   PVc Pipe is rigid and won’t bend.  Very few people can do this process using PVC.  In 26 Years of installing Drains, I have only done it 3 times using PVc.  It is very Difficult and Frustrating.

Step 5 Watch a Video on Light Concrete Work if available.

Step 6 Connect the curb fitting to the drain pipe and install cement around it.  I have had the most success using a ” Quick Set” concrete that comes in a small bucket and has an “Acrylic” Additive or Base.

I don’t recommend cutting the curb yourself and installing a curb outlet if you are only going to do this once in your life.  If you are are or will become a drainage contractor, then this is a skill that you definitely need.

Problem Drainage Area

This is a good spot for a French Drain

A final thought on Intakes as part of a Drainage System.  Remember, an Intake is a French Drain or a Surface Drain.  It is the part of the Drainage System that draws water into the Drain Pipe.

Once you have decided where and  how many Intakes your drainage system needs,( how many and what kind of Drains ) the next thing to think about is the Transition other wise known as the Drain Pipe.  For a typical Drainage System there are three choices of Drain Pipe by Size.  ( 3 Inch, 4 Inch, and 6 Inch )

Three inch is least expensive but can easily be overwhelmed if a large amount of water needs to be drained away.

Four inch is by far the most common.  It also can be overwhelmed if too many Intakes (Drains) are connected to it.

Six Inch Drain Pipe is almost never overwhelmed, but it is bulky and hard to work with and is by far the most expensive.

4 inch Drain pipe

4 Inch Drain Pipe before it goes in the trench

What Do I mean by overwhelmed?  It means that water is going to the Problem Drainage Area faster than the Pipe can move it away.

This is very important to some people and not important at all to others.  Here is why!

house flood

This is a great place for a French Drain

Really, think for a minute about why you want to install a Drain in the first place.

Do you want to prevent water from ever reaching Problem Drainage Area?  Or is it OK for water to reach the Problem Drainage Area and then be drained away over time.

If, for example, you are trying to protect your prize plants, you don’t want flood water reaching them at all.  Or you might be trying to prevent water from reaching part of your house because it then runs into the basement.  You don’t want water, under any circumstances,  to reach a specific spot or area.   If this is the case,  You want a

Flood Prevention System

A Flood Prevention System is actually a type of Drainage System, However the goal is different and that can change the Design.

On the other hand if you don’t mind so much if water gets into the Problem Drainage Area,  you just want it to drain away in a relatively short amount of time.   This is called a

Drainage System

If your motivation is to have a Flood Prevention System,  Then the Drain Pipe being overwhelmed is a really bad thing.  It means that your Flood Prevention System has failed.  Your Drain Pipe could not move the water fast enough to provide the Safety that you desire.   Your plants have drowned and your basement has flooded.

If your motivation is to have a Drainage System, Then the Drain Pipe being overwhelmed is not so bad.  Even though water is flowing into the Problem Drainage Area faster than the Drain Pipe can take it away,  The Drain Pipe is still moving a lot of water and eventually the rain will stop and the Drain Pipe will catch up.  In relatively a short amount of time, the water will be gone.

What you want, dictates how you design your Drainage System!

Drainage Systems are not as robust as Flood Prevention Systems.  A Flood Prevention System has all the same basic concepts and structure as a regular drainage system, just more!

If you want a Flood Prevention System, the goal is to intercept water before it runs somewhere.

This means:

  1.  More Intakes ( Lots of Drains) French Drains Or Surface Drains
  2.  Larger Drains,  6 inch French Drains, or 18 inch Surface Drains for example
  3.  Larger Transitions ( Larger Drain Pipe )
  4.  More Transitions (  More Drain Pipes )
  5.  Larger Drainage Exits
  6.  More Drainage Exits

I know we haven’t talked about Drainage Exits, but we will in the next blog.

A Drainage System is less of everything listed above.

Obviously a Drainage System is less expensive, less evasive, and easier to install.

Before we get into Water Movement, we need to discuss Surface Drains.

Surface Drains come in many shapes and sizes.  The two most common are Basin Drains and Channel Drains.

A Basin Drain has a Square Grate and it sits on top of a catch basin.  It will have a single pipe connected to it or it will have a drain pipe running into it and a pipe running out of it.  We used this picture in a previous blog, but I want to show it to you again.

Surface Drain Connection

Surface Drain connected to a Transition Pipe

Below is a Basin before the pipe is connected to both sides.  The pipe is cut and connected to one side.   Another piece of Drain Pipe is connected to the other side.  The Drain pipe does not run straight through the basin.  Water must have a way to enter the Drain Pipe.  The Surface Drain in the picture is the most common size used in residential applications.  The Drain Pipe connecting to it is 4 inch ADS Solid Drain Pipe.

For a Surface Drain to work well it must be placed in a low lying area of standing water.  It is not intended to intercept moving water or to drain away Sub-Surface water.

 

In review, detecting Surface Water is straight forward.  You can observe how it flows into the Problem Drainage Area.

Sub-Surface water is not so easy.  You can’t see it move into the problem area.  So What do you do?

First take a look at your soil.  What type of soil do you have?

Soil with a lot of clay will have less Sub-Surface Water, Maybe none at all.  If you do have some it will move into the area slowly.  If you have sandy soil the underground water will move there in a hurry.  Most people will have something in between.

To be sure, a few simple tests can help.

Next check the problem drainage area when there is no water standing in it.  Is it soft and mushy when the surrounding area is more firm?  This is an indication that Sub-Surface Water is still flowing into the area.  Another way to collect information is to dig a small hole about a foot deep in the area. Check it every day for several days.  If water is standing in the hole, you have a Sub-Surface Water issue.  How fast it flows into the hole is also important.

OK, you have Sub-Surface water along with Surface Water in your problem drainage area.  Your Choice for the correct “Intake” for your Drainage System should be a French Drain.

OK, You have no Sub-Surface water. You only have Surface Water flowing into the problem area.  You need a French Drain If you are trying to intercept the water as it comes into the area.  Many times water will run around the surface drain and still flood the area.  Also the Surface Drain is much more easily overwhelmed and water will run past it that way too.  Again, this is very important,  If you are trying to intercept water before it gets to where its going, don’t use a Surface Drain.

A Surface Drain should be used in a Medium to Low Volume Water situation.  The water needs to be stationary or moving very slowly.  It should be placed in an area that is the lowest point in the Problem Drainage area.  They also work well in smaller confined areas such as pool decks, along sidewalks, or in flower beds.

More than one Surface Drain can be connected to one drain pipe in a “Daisy Chain” of Drains if you have several low spots in a larger area.

In many cases a small french drain can be installed in almost every place that a Surface Drain might be installed.  People opt for a Surface Drain over a French Drain because they like the way the Surface Drain looks more than the way the French Drain looks.  For some People, Looks are more important than functionality.

Setting a Surface Drain in Concrete such as a driveway or a Sidewalk is a good application for a Surface Drain.  Many times it is better to install a French Drain in your yard over a Surface Drain.  What ever makes you happy!

French Drains can be made to look very decorative.

French Drains can be decorated with many types of stone

In conclusions,

French Drains are used for :  1.  Higher water volume situations  2.  Intercepting moving Surface Water  3.  Solving Sub-Surface water problems

Surface Drains are used for: 1.  Smaller water volume situations  2.  Standing Surface Water that has reached its destination   3.  Smaller and more confined areas  4.  Set in concrete such as sidewalks or Driveways

French Drains are Perforated Pipe in a Drainage Trench with the dirt removed.  Gravel is then placed surrounding and on top of the French Drain Pipe.  Typically French Drains For Residential and Small business applications have perforated pipe that is 3 Inch, 4 Inch or 6 inch.  The larger the pipe the more water your Drainage System can handle.

I personally believe that ADS French Drain Pipe is very good.  Pvc French Drain pipe is very bad.  I have made a very good living replacing PVc French Drain Pipe with ADS French Drain Pipe.

ADS holds up over time much better.  It has a Neoprene Sock around the perforated pipe that keeps dirt from clogging the drain pipe over time.  PVc French Drain Pipe becomes brittle and cracks and deteriorates in only a few years.  It will not have a “soc” around either.  If you are not sure which one is which, Ads is Black and Pvc is white.  The choice is yours.

Anyway, Sorry! i’ll step off my soap box.

A French Drain is designed to move a large amount of water in a large area such as a yard, flower bed or on the side of a house.   They are installed in dirt and are covered with some type of crushed stone or gravel.  A trench that a French Drain is going to be installed in looks like this.

A Trench Liner can be installed in the trench as well.   It is cloth that is designed to go in the empty trench before the Perforated Pipe and the Gravel is installed.  The Trench liner can be found at most retail drainage outlets.  If you can’t find any, ” Weed Matt” in the garden section that goes in flower beds works very well.

A trench liner will increase the cost of a French Drain.  Many times they are not necessary.  Sometimes they are very necessary.

A Trench Liner will maintain the integrity of the Drainage Trench over time.  But, If you have a “Sub Surface Water Problem they may impede how well your French Drain Works.

Don’t worry, It will make more sense as you read this blog and ones that follow.

A completed French Drain looks like this.

Moving a large volume of water is not the only reason to install a French Drain.

When Diagnosing a Drainage Problem, the first thing to consider is how does the water get into the Problem Drainage Area.  The most obvious way is by flowing over the top of the ground.  This is called “Surface Water.”  Water comes from somewhere else by flowing over the ground.

I know that’s overly simple but right now its necessary.

French Drains do a Great Job in moving Surface Water away from the flooded area.  For example, the water flows out of my neighbors yard, down the hill and into mine.  It then runs into my French Drain, Then into the drain pipe, it then moves through the drain pipe to the exit point at the curb outlet  and into the street.

( Simple Enough)  Ahh, but there is more!

The thing that people miss, don’t anticipate, and don’t understand, is “Sub-Surface Water.”  Sub-surface water is not accounted for many times, in the design of a Drainage System.

OK, Think about the example above again, only this time the water is flowing underground as well as over the surface.  So, in fact, you have at least two sources of water feeding your Drainage Problem Area.

Why is that important?

Surface Drains are not designed to move “Sub-Surface Water.”  Just as the name says, Surface Drains move Surface Water.

Many times a Surface Drain is installed out in a yard to solve a drainage problem instead of a French Drain.

Surface Drain Connection

Don’t get me wrong, Surface Drains are great!  I have installed literally thousands of them since 1993.  They do an awesome job when they are installed for the right reasons.  Problem is they do absolutely nothing to drain “Sub Surface Water”.  In later blogs we will discuss the correct application of a Surface Drain.

Back to the French Drain.  A French Drain can take in water topically. ( In the top of the drain) It also can take water in Laterally. ( Through the Sides underground)

So you must determine before installing a Drainage System,  how the water gets into the problem drainage area.

Is it Surface Water?  Sub-Surface water? Or Both?  Our next blog will discuss this.

A French Drain is just a part of a Drainage System.  Many people refer to basically any type of Drain in or around their home as a French Drain.  This actually in not correct.

 

Before you can really understand what a French Drain is, you first must be familiar with a Drainage System and what it involves.

A Drainage System has three parts.  It has an “Intake” to bring water into the Drainage System.  It is placed in a low area where water is standing or is in area where water sometimes runs across it over the surface or under the surface or both.  An “Intake” will be a French Drain, Surface Drain or Sump Pump.

In a Simple Drainage System there will only be One “Intake.”  In a Complex Drainage System there will be several Intakes.  They may vary in type and size.  For Example, You may have a Drainage System with a Surface Drain, and a French Drain and a Sump Pump all as separate  Intakes in the Drainage System.  The Intakes will vary in number and type depending on what water issues you are trying to fix.

The “Transition” is the second part of the Drainage System which is the Drain Pipe that moves the water out of the area that is flooded.  It is your water “High Way, ” as it were.  Typically there are two types of Transition Drain Pipes that will be covered later.

Finally you have an “Exit” which releases the water from the drainage system.  It must be in an area that is lower than the French Drain or Surface Drain that is you “Intake.”

 

 

A French Drain  is a perforated pipe that is basically full of slits or holes.  A trench is dug across the problem drainage area.  The dirt from the trench is hauled away.  The perforated pipe is placed in the trench.  The Drainage trench is dug deep enough so that the perforated French Drain Pipe is several inches below ground level when placed in the trench.  Next gravel or some type of crushed stone is placed on top and around the French Drain perforated pipe until the trench is full.

 

Once a French Drain is completed you will see gravel on the surface in a place where dirt use to be.

A French Drain is designed to take in and move a large amount of water.  It covers a large area with water standing on or moving across the area.  It needs to have some “Slope” or “Fall” to drain the water.  The pipe needs to run down hill to the exit point to release it from the Drainage System.  If it is up hill in all directions from the French Drain then there is a problem.  We all know that water will not flow up hill.  Some times this can be overcome when it is only slightly up hill by digging the trench deeper as you go up hill.  Still the exit point in the Drainage System must be lower than the French Drain where the water is taken into the drainage system, or the water will never drain.

In conclusion, a French Drain is a perforated Pipe in a trench covered in gravel.  It is the “Intake” part of a Drainage System.  It covers a wide area and needs to be higher than the exit point of the Drainage System.

This is the first in a series of blogs about French Drains and all other types of Drains as well.  If you would like to learn more just Click on the “Next Blog” below.

French Drain Installation Or Do You Need A Surface Drain?

Many Folks don’t know the difference.   Actually there are many differences and a few similarities.  One difference is, a French Drain takes in a larger amount of water into the drain Pipe than a Surface Drain.  There are advantages to Surface Drains as well.

Oklahoma Drainage and Sprinkler Repair recently diagnosed a Drainage Problem in  South Oklahoma City.  The Home owner had a sump Pump in their basement that was fed from a French Drain outside the Basement Wall.  The French Drain was 14 feet down along the Stem wall of the house.  The French Drain Pipe was cheap and had collapsed.  We brought in a Mini Excavator and dug up the pipe and replaced it with Durable ADS 4 inch perf/soc French Drain pipe.  In the end, we were able to dig up the pipe and Replace it.

Next we installed a new exit for the water by installing a curb fitting.

No more flooding in the customers basement.  A few weeks later our customer was able to lay carpet in the basement with no problems.

FRENCH DRAIN  CONNECTED TO GUTTERS

Many different types of Drains can be hooked together by one Drain Pipe.  The Drain Pipe then running to an Exit Point makes up a Drainage System.  One common type of Drain used in a Drainage System is A “French Drain.”  Many times a French Drain is installed close to a building foundation or in a low area next to a home or business.  This puts the French Drain in close proximity to Gutter Down Spouts.  Rather than have water come off the roof and out the Down Spout and on to the ground below, many times it is much better to tie a Gutter Down Spout Directly into a French Drain or near by Drain Pipe depending on the Drainage System Design.   Connecting The Down Spouts Directly into a French Drain is much  more efficient and causes suction to occur in the French Drain.  Connection of Gutter Down Spouts to a French Drain makes the Drainage System work better.

Do you have water standing in your yard after a hard rain? Does your sidewalk become a moat during a thunder-storm? Is standing water causing your foundation to deteriorate and break down? Is water seeping into your home and causing mold?

Storm-water run off can cause many types of problems. Oklahoma Drainage and Sprinkler Repair can diagnose your drainage issues and design a Drainage System to fit your specific needs. We install many types of drains including: French Drains, Channel Drains, Surface Drains, Basin Drains, Trench Drains, Basement Drains, and Sump Pumps.

Just what is a “French Drain?” Many times people incorrectly

A French Drain can protect your foundation!

use the phrase, “French Drain,” when they mean “Surface Drain” or “Channel Drain.”

A basic French Drain consists of a Perforated Drain Pipe in the bottom of a trench. The French Drain Trench runs through a Problem Drainage Area that needs to be drained.   The French Drain Pipe is perforated (Full of Small Holes) and has Neo-Prene Soc around the pipe.  This soc helps prevent debris from clogging the French Drain Pipe.

Perforated French Drain Pipe

The dirt that was taken out to make the trench is hauled away. It is replaced by some type of small stone or gravel depending on what is desired or available. I prefer crushed 1 inch lime stone. It is the most economical option in my area. Pea Gravel or some other type of small stone can work just as well. The lime-stone or gravel is placed in the trench on top of the perforated Drain Pipe and filled all the way to the surface (ground level). In some cases where the French Drain needs to be deep or is being placed in sandy soil, a special trench liner must be placed in the trench before the perforated Drain Pipe or the Gravel are installed. This helps maintain the integrity of the trench over time. It also increases the cost of the French Drain and the amount of time to install it. I install a trench liner in a French Drain about 20% of the time. Most of the time a liner in not needed.

French Drain is designed to handle a large volume of water and cover a large area. The Drain is anyplace the trench goes. It has many applications and can be used in many situations. It can be installed by itself or incorporated into a Drainage System with Surface Drains or Gutter Down-Spouts connected to it.

French Drain with Colored Gravel

The main downfall of a French Drain is that they, for the most part aren’t very pretty. They don’t look very nice in a yard once they are completed.

Depending on the area the French Drain is installed and the type of grass around the French Drain, will dictate whether grass grows over the lime stone. Grass can grow up and through the gravel in the French Drain over time eventually covering the gravel. This is Ok. It won’t have a measurable effect on the performance of the drain.

DON’T COVER THE GRAVEL IN THE FRENCH DRAIN WITH DIRT. THE FRENCH DRAIN WON’T WORK IF THE TRENCH IS CLOGGED WITH DIRT. DON’T EVEN INSTALL IT IF YOU ARE GOING TO COVER IT UP WITH DIRT.

DECORATIVE STONE CAN BE USED TO COVER A FRENCH DRAIN AND THEY LOOK GREAT AND LAST A LIFETIME.

Drainage Systems can be made up of one drain or a combination of many drains.  Drainage  problems can be very complex.   Complex Drainage Problems may require a combination of several different types of drains all inter-connected and working together. Many times a French Drain, might be connected to a Surface Drain,  which then could be connected to another French Drain.   Other times the drainage problem may be simple and straight-forward requiring only one drain or several of the same type of drain connected together.

Cutting The Curb and Installing Curb Fitting With Acrylic Cement
Cutting The Curb for French Drain Outlet

An example of a complex drainage system would be:  A French Drain in the back yard connected to a Surface Drain near a flower bed connected to several gutter downspouts, which are connected to a Channel Drain going across a driveway, which is connected to additional French Drain in the front yard, which runs to a Curb Fitting that lets all the water drain out on to the street.

A simple Drainage System might consist of a French Drain  which runs to a Pop-up Emitter which lets water drain over the curb and into the street.

An “Exit Point” is the term used for where all the water leaves the Drainage System.  Determining the Exit Point is very critical.  It is one of the first things we do when diagnosing a Drainage Problem.

Drainage Systems can:

1.  Keep water away from foundations — A French Drain is best because it can move Surface Water and Sub-Surface Water (water moving under ground) away from the foundation.  Many times less experienced companies install Surface Drains to keep water away from foundations.  This can be a big mistake.  A Surface Drain can’t move or drain Sub-Surface Water.   Also A Surface Drain often can’t move enough water fast enough and easily becomes overwhelmed during a heavy rain.  A Surface Drain also can’t cover or protect a broad enough area. Surface Drains should be designed in a Drainage System to be located in smaller Drainage Areas moving moderate amounts of water.  Surface Drains look better than French Drains.  If ,”appearance” is more important than Drainage Capacity, Go with the Surface Drain.  Just know what you are getting into and what your expectations should be. One side of a foundation alone,  can be over 100 feet.  A 4 inch or 6 inch French Drain is best when protecting a large area such as a foundation.

2.  Keep water away from small or enclosed areas.  This might be a low area just through a gate on the side of a house, or the low area between a flowerbed and the wall of a house, or standing water on or near a sidewalk or driveway.  These types of Drainage Problems are best served with Surface Drains.  A Surface Drain can move water away from a low area that is relatively small.  This can occur in yards, flowerbeds, sidewalks and driveways.  A surface Drain is designed to move Surface Water away from a problem area to a predetermined exit point.  Surface Drains are available in many sizes.  How quickly they remove standing water is usually determined by the size of the pipe that is connected to the drain.

Simply put, a Drainage System is one or a group of underground Drain Pipes that take water away from a place that has water standing on it or flowing across it.  The water that is in the problem area, can be causing damage or may be inconvenient or both.  (Usually Both)  A simple Drainage System is a Drain for the water to enter, a Drain Pipe to move the water away from the Drain, and an Exit Point for the water to be released out of the Drain Pipe.

Drainage Systems quickly can become more complicated.  Considerations must include:

How does the water get to the problem area?  There may be one or many sources.

Water Sources:

1.  It falls from the sky directly

2.  It flows down hill over the surface (surface water)

3.  It flows underground under the surface (sub-surface water)

4.  It flows from the edge of a roof ( There may be many roofs near the problem area, neighbors etc.)

5.  It flows from a gutter downspout

6.  It flows over the edge of a gutter because the gutter is too small is is clogged

7.  It flows up from the ground (seeps and springs are common in Oklahoma)

8.  It flows from a sprinkler system use ( yours or your neighbors)

9.  It flows from a leaking pipe ( water mains, water meters, water lines, sprinkler pipes, sprinkler valves)

There are other reasons for Drainage Problems, the above reasons are just the most common.

Once the number of water sources is determined, a rough estimate of the amount of water that needs to be drained away on average must be estimated.  This can be simplified down to “SMALL, MEDIUM, OR LARGE AMOUNTS OF WATER TO BE DRAINED AWAY.  You don’t have to be an engineer trying to calculate fluid dynamics.  Experience at diagnosing drainage problems helps however.  How much water needs to be moved will help determine the type and size of the Surface Drain or French Drain that needs to be installed.  It also helps to determine the size of Drain Pipe required for the Drainage System.  A good rule to follow is, “If in doubt, install a larger Drain and Drain Pipe.”  Unused Drainage Capacity is better than property damage caused by a Drain that is overwhelmed by too much water.

For home and small business use typical materials used are:

6 inch, 9 inch, and 12 inch Surface Drains

3 inch, 4 inch, and 6 inch Drain Pipes

3 inch, 4 inch, and 6 inch French Drains

French Drains move more water than Surface Drains —

French Drains move Surface Water and Sub-Surface Water

Surface Drains move Surface Water only

Surface Drains look nicer than French Drains in most cases

Once the type and number of drains is determined and what size Drain Pipe will connect them, an exit point must be selected.  (Where is the Drainage System going to take the water to and release it?)

The Drainage Curb Fitting is installed when the desired exit point for the French Drain will release the Drainage Water into the Street.   The Drainage Curb Fitting is rectangular in shape and made to be installed through the curb.  A small section of Curb is cut out with a concrete saw.  The Section is a few inches wider than the Drainage Curb Fitting.  We then install new concrete around the curb fitting.  Once the concrete has dried, the Drain Pipe coming from a French Drain or Surface Drain is connected to the Drainage Curb fitting and then covered with dirt.
