French Drain in Central Oklahoma

French Drain Installation is what we do!  CMG has been installing Drainage Systems in Central Oklahoma for over twenty years.  We solve all types of Drainage Problems for residential and commercial customers.

Recently we installed a Drainage System in Moore.  Our customer had a new home.  Originally their home was destroyed in Moore‘s last tornado.  Every time it rains their back yard turns into a pond.

CMG installed a 6 inch French Drain in the back yard and connected the gutter down-spouts into the French Drain.  From that point we ran ADS solid Drain Pipe all the way to the street.  At that point the curb was cut and a Curb Outlet was installed with acrylic concrete.  The French Drain did the trick.  Drainage 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.

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.

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 March 2011

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.

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.

 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 IN EDMOND OKLAHOMA, DRAINAGE CONTRACTOR

Recently CMG 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.

 

French Drain is completely different from a Surface Drain.  A basic French Drain consists of a Perforated Drain Pipe in the bottom of a trench.  A  Trench Liner is sometimes used depending on the Drainage System Design and the type of soil.   The Drain Pipe should have a neoprene sock around the Perforated Drain Pipe.   This is to ensure that the Drain Pipe does not become clogged. A trench is dug that is slightly wider than the French Drain Pipe that is being used.  There are several sizes of French Drain Pipe.   Three Inch, Four Inch, and Six Inch are the most common sizes of French drain Pipe. The dirt that is 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.

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.

French Drain Information in Oklahoma City, Norman, Edmond

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.

Good Information about French Drains and Drainage Systems

French Drains, Surface Drains, and Channel Drains are the three main ingredients of residential and business Drainage Systems.  Simply put, French Drains are used in large areas, Surface Drains are used in smaller areas and Channel Drains are used in and across Cement.

Some Simple rules about French Drains and Surface Drains.  A French Drain should be installed when there is a large volume of water to be drained over a large area.  Surface Drains are needed when the water volume is smaller and the Drainage Area is small and focused.  French Drains move away Surface Water and Sub-Surface water (water that flows under ground).  Surface Drains move only surface water.

French Drain Design must take into account many variables.  One consideration for a French Drain that many times is missed, is the type of soil.  French Drain Design must take into account the type of soil that the French Drain runs through.  If the soil is “Tight or made up of Clay, A French Drain Liner may not be necessary.  The Gravel or Limestone that is used to fill the French Drain trench may be all that is needed to maintain the integrity of the trench over time.   This means that dirt will not mix in with the French Drain Gravel and clog it up over time.  This is not the case however if your soil is sandy or loose.  A Trench Liner should be used to prevent this type of soil from moving into the gravel of the French Drain.  Trench Liners are relatively inexpensive and are not hard to install.  If you are not sure what to do then install the Trench Liner in the French Drain.

 

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.

Today we installed a 6 Inch French Drain at an apartment complex near Lake Heffner.  The French Drain started in the back yard of one unit.  The Drain Pipe went under the fence and into the adjoining unit’s back yard.  The French Drain then looped around their patio and out under their fence to the west.  To get the 6 inch Drain Pipe to the correct Exit Point, we had to cut out 30 feet of sidewalk and run the French Drain Pipe under the sidewalk.  Next, we replaced the sidewalk with new concrete.  Finally, we dug a drainage ditch across the front yard to the parking lot.  We covered the Drain Pipe with sod that we carefully removed when digging the trench.  At the edge of the parking lot a 6 inch Pop-Up Emitter was installed to release the Storm water.  Seven Gutters were connected directly into the Drainage System along the way.

French Drains can be installed by themselves, or as part of a Drainage System that uses other French Drains, Surface Drains, or other Drain combinations.  Typically a French Drain is used to protect a broad area that has a lot of standing water.  A French Drain might run along side a homes foundation, or beside a driveway, or on any Drainage Project where Sub-Surface water is the primary problem.  If water is running toward your home under ground ( through sandy soil), A French Drain is the only Solution  for draining away water flowing under ground.

After Diagnosing a Drainage Problem in Oklahoma City, We installed a 6 inch French Drain that went all the way around the pool in the back yard and then ran all the way to the street on both sides of the house. The French Drain made the shape of a horse shoe. The Drainage System had two Curb Outlets installed through the curb at the street. This gave the French Drain two different directions to allow the water to flow to the street.  Two Drain Outlets allowed the French Drain to move a huge amount of water during heavy rains.   A few weeks  later we got a call from our customer after a heavy rain.  She was very happy.  The French Drain did a great job protecting her pool.  All the Storm Water was diverted around the Swimming Pool.

French Drain installation is a big focus for CMG during our 21st year in business. A French Drain is one part of a Drainage System.  A French Drain can be connected to other types of Drains or Gutter Down-Spouts and then run through Drain Pipe to an Exit point where the water is released.

A Drainage Exit Point is the area where water goes to be released when it comes out of the Drainage System. The two most common exit points for a Drainage System are a Pop-Up Emitter or a Curb Fitting.
A Pop-Up Emitter is a Fitting on the end of a Drain Pipe that has a lid that pops up and releases water. When water drainage is complete, the lid shuts back.

CMG 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.   The CMG 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.  CMG 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.

Channel Drains are one kind of Surface Drain that we install in concrete.

The most common Drain that we install is the French Drain.  This is because the French Drain is versatile.  It can handle Surface Water Problems or Underground Water Problems (sub-surface).  A huge mistake that many people make is assuming that water gets to a Problem Drainage Area by flowing over the surface only.  For example, if water is flowing down hill underground toward your home’s foundation, the only way to stop or intercept it is with a French Drain.  Water can flow laterally into a perforated French Drain Pipe.  It is then diverted away from the Problem Drainage Area to an Exit Point.

French Drain is completely different from a Surface Drain.  A basic French Drain consists of a Perforated Drain Pipe in the bottom of a trench.  A  Trench Liner is sometimes used depending on the Drainage System Design and the type of soil.   The Drain Pipe should have a neoprene sock around the Perforated Drain Pipe.   This is to ensure that the Drain Pipe does not become clogged. A trench is dug that is slightly wider than the French Drain Pipe that is being used.  There are several sizes of French Drain Pipe.   Three Inch, Four Inch, and Six Inch are the most common sizes of French drain Pipe. The dirt that is 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.

When we run Drain Pipe across yards to an Exit Point, the sod usually can be put back into place and in a few days you can’t tell a French Drain was ever Installed.
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.
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 French Drain.  In some cases thick grass growing up through the French Drain will create a natural “Thatch” filter.  This makes the French Drain invisible.  The trick is to allow the grass to grow over the French Drain Gravel without covering it up with dirt.  Grasses such as Bermuda which grow well in the sun will put out runners and new roots and will grow up and through the French Drain.  This will not affect the performance of the French Drain.  The problem is that some times depending on the type of soil involved, it may take a long time to completely cover up the French Drain.  Sprinkling grass seed down in the gravel will speed up the process.
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.
