French Drain Info and Design, Oklahoma City, Yukon, Mustang

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

A French Drain can protect your foundation!

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

Surface Drian

 

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

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 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.

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

 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.

Six Inch French Drain Installed along Foundation in Edmond

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.

 

A  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.

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.

Channel Drain Installed by CMG In Yukon

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.
