French Drain Information and tips, Oklahoma City, Norman, Edmond

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

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.

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 March 2011

A 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.

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.

Edmond Oklahoma has been the location for many French Drain Installations for CMG 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.  CMG 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.

Connecting a gutter to a Drainage System

CMG 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.

6 inch French Drain

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.”  He also checked us out on Angie’s List and Found that we were one of the highest ranked Drainage Contractors in the state of Oklahoma for installing French Drains.

Drain Pipe running to Pop-Up Emitter

The Gentleman gave us a call to set up an appointment.  CMG 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.

Installing a curb outlet for a French Drain in Norman

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.

Problem solved!

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.

DONT 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.

French Drain Information and Ideas

French Drains can utilize  several types and sizes of French Drain Pipe.  An older type that is not commonly used any more is 4 inch PVC Pipe with large half inch holes drilled in the Pipe.  This doesn’t work very well,   Because the holes are too large and the number of holes in the French Drain Pipe are too few.  Also there is no filter or “Soc” around this particular French Drain Pipe.  If it is used in sandy or loose soil the holes will clog and the pipe will fill up with sand.  PVC French Drain Pipe should be avoided.

ADS French Drain Pipe is much better, the holes are smaller and much more numerous.  It also comes inside a soc that acts as a filter and helps keep sand and debris out of the French Drain Pipe.  It works very well.

For Small business and Residential French Drains, Four inch ADS Perf/Soc French Drain pipe is adequate and the most common.  It is used for the majority of all French Drains installed.  French Drains can be installed using 3 inch ADS Perf/Soc but many times it is too small and can be overwhelmed by a heavy rain or from a bad design.  (Too many gutter down spouts connected directly into the French Drain, For Example)  Three Inch French Drain Pipe should be avoided if possible.

Six inch  ADS Perf/Soc French Drain Pipe is usually a good idea when possible.  It carries a much larger volume of water.  Six Inch French Drains are rarely overwhelmed.

Installing Gravel on top of a 6 inch French Drain

The Drawbacks to 6 inch French Drain installation are:  1.  The Materials Cost is higher for six-inch French Drain Compared to Four Inch Pipe.
                                                                                                                    2.  Many times 6 Inch French Drain Pipe is too large for many applications, Such as going under a fence or sidewalk.  
                                                                                                                   3.  The trench for a 6 inch French Drain must be much larger than a 4 Inch
                                                                                                                   4.  The amount of gravel or limestone or River Rock used to Cover the 6 inch French Drain is Much larger
 
All things being considered, the performance and longevity of a 6 inch French Drain is well worth it if you are trying to protect something of value to you!  If the higher cost and the additional labor and materials are not a problem and 6 inch French Drain pipe is not too big for what you want to do then a 6 inch French Drain would be the best.  
French Drain Installation can prevent water from getting into your air conditioner floor ducts.

A common Drainage Problem for people in Central Oklahoma is ground water seeping into floor air conditioner  ducts.  This can cause very costly damage to a home or business.  Water-proofing Ducts, or even worse, trying to remove mold from duct work can cost big bucks.   Structural Engineers typically recommend  French Drain Installation  to keep water out of ducts.   French Drains catch and remove sub-surface water that is traveling underground toward a foundation. It is intercepted by the French Drain before it can seep under the building in question.   Because this water is not usually seen, it may not be taken into consideration when diagnosing drainage problems.  Surface Water traveling to a problem area is obvious as it flows on the surface in plain sight.

CMG has 21 years of experience Diagnosing Drainage Problems.  We always check for sub-surface water flow into any Problem Drainage Area.  Again, French Drains are intended to handle water moving both underground and above ground.

French Drains can also be used to remove water that is standing in a large area such as up against a foundation or along a fence.  French Drains don’t do so well in tight small areas.  These areas are best suited for a Surface Drain with a grate.  Many times we install French Drains along foundations after a home owner has spent large amounts of money on foundation repair.

Several Foundation Repair companies and Duct waterproofing companies recommend CMG for French Drain Installation.    Typically we install a French Drain by itself or as part of a Drainage System  after they have completed their repairs to the foundation or duct work.

Recently we installed a French Drain in Norman.  Our customer had water running down the hill from his neighbor’s Sprinkler System into the North wall of his house.  Over time the ground became saturated and water seeped under the wall and into his floor air conditioning vents.  We installed a 4 inch French Drain along the North wall of his house to provide a barrier to the continuous water flow.  In a few days the moss that was growing on the side of his house began to die from lack of water.  A Duct company came in and cleaned out is vents.  The French Drain removed the surface and sub surface water that was flowing into his home.   Problem solved.

 

 

 

French Drain, Drainage System Information, Surface Drains

The term, “French Drain” gets thrown around a lot.  Many times people say they need a “French Drain,” when they mean Surface Drain, or Channel Drain.  It is becoming a Catch-All Phrase that may refer to any type of drain.  French Drains provide specific benefits that are different from Surface Drains.

 The French Drain Installation we did this week was a little more difficult than normal.  Many times the route that a Perforated French Drain Pipe must travel to its exit point is not very easy from an installation point of view.  French Drains may have to travel through tree roots, (big ones) under sidewalks, through retaining walls, around swing sets or dog kennels or Mom’s Prize Rose Bush.  The 4 inch French Drain we installed this week was in Oklahoma City south of 23rd in an old part of town where all the houses were old 2 or 3 story homes with lots of huge Elm Trees.  The Elm Tree in Question actually was just an old stump that had been topped out but not completely removed.  They left the roots just for us!  The roots were growing into the homes foundation and were right in the way of the path of the French Drain.  Forty feet of solid Elm Roots and 4 chain-saw blades later CMG was successful in running a new French Drain through a tree stump.  Yuck! “Well you gotta  do what you gotta do!”

A little info about French Drain Pipe and Tree Roots.  Normally tree roots don’t seek out and penetrate French Drain Pipe.  Tree roots seek moisture and residual water that may stay inside Solid Drain Pipe.  French Drain Pipe is perforated.  Water that does not reach the exit point of the French Drain will seep out of the Pipe into the surrounding dirt.  Solid Drain Pipe that is used with Surface Drains can be penetrated and eventually clogged by roots if the pipe does not have good slope or “Fall”.  If the solid pipe does not drain well and has residual water, tree roots will seek it out.

Drainage Systems are designed to protect your home or business from standing water.  Storm-Water Runoff can cause damage in many ways.  Water from your gutters can seep down into your home’s foundation if it has no good way to drain off.  If the temperature then drops below freezing, the water around your foundation can freeze and cause serious damage to the home’s foundation.  Foundation repair can cost more than a Drainage System.

Drainage Systems typically make use of , French Drains, Surface Drains, or Channel Drains.  Depending on the Drainage Problem, A Drainage System may utilize one or several types of Drains.  CMG might install, for example, A Surface Drain in the middle of a driveway that runs to a gutter that is connected into the drain pipe.  The Drain Pipe might continue to a French Drain running parallel to a homes foundation.  Next the drain pipe might continue to a channel drain cutting across a sidewalk.  The Drain pipe might then reach its exit point running out through a curb fitting installed and cemented through the curb.

A Surface Drain basically is a basin that has a grate on the top.  A drain pipe is connected to the basin below ground.  The water flows in through the grate and down into the basin.  The water then exits the Basin through the Drain Pipe and move toward the exit point of  the Drainage System.  Surface Drains are designed to handle water that accumulates in a low areas.   These areas should not be too large or broad, and the water that drains into a surface drain should not be moving very fast.  Surface Drains can become overwhelmed if they are placed in an area that must move a large volume of water, quickly.  Selecting the correct drain for the specific drainage problem is a benefit that CMG provides through twenty years of experience.

French Drain Installation and Design

French Drain Installation —   French Drains are designed to do a lot of things.  If you have an area that has unwanted water standing in it or running across it, a French Drain can be the answer.  A French Drain is a trench that runs across the Drainage Problem Area.  A French Drain Pipe is placed in the bottom of the trench.  The French Drain Pipe is perforated with thousands of small holes.  In most cases the Drain Pipe has a nylon soc around the pipe to act as a filter for the French Drain.  The French Drain trench is then filled with some type of small rock or stone.  CMG typically uses crushed 1 inch Lime Stone to cover the French Drain Pipe.  The dirt that was dug out of the trench is taken away or spread out around the French Drain.  The Lime Stone replaces the dirt and fills the French Drain Trench all the way to the surface.

When water come in contact with the French Drain, it seeps down through the stones and into the French Drain Pipe.  It then flows through the Drain Pipe to the exit point.  Typically a French Drain will have two possible exit points.   The First is called a “Pop-Up Emitter.”  It is a Green Lid on top of a release basin for the French Drain.

The second type of Exit Point for a French Drain is a “Curb Fitting.”  The Curb Fitting is installed through the curb going out into the street.  The French Drain Pipe runs to the Curb.  The curb is cut out and the Curb Fitting is cemented through the Curb.

French Drains are designed to move large amounts of water.  A French Drain moves water away from the Drainage Problem area from the Surface like a large Surface Drain, But also below ground, or sub surface.  Most people don’t take into account the water that flows to a problem area underground.  Sub surface water flow is not eliminated by a Surface Drain.  A French Drain can move away water that is below the surface of the ground and drain away water that is on the surface.

CMG Sprinklers and Drains designs and installs Drainage Systems. Water Drainage is a big concern to home owners and small businesses.  Standing Water from Storm-Water runoff can cause all kinds of problems.  Concrete in driveways, sidewalks, and foundations can be damaged.  Prolonged Drainage Problems allow mold to occur along with deterioration to plants, trees, and property.

CMG Sprinklers and Drains designs Drainage Systems to deal with Water Drainage problems.  We provide Free Estimates for all of Central Oklahoma. CMG utilizes: French Drains, Trench Drains, Surface Drains, Channel Drains, Basin Drains, and Sump Pumps.  Drains can be simple using one type of Drain, or complex using several types of Drains.

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 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 inclosed 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 —

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.DSC00560

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.
