French Drain information and answers

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.

French Drain in Flower Bed in Edmond

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.

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.

Installing Curb Outlet for French Drain in Oklahoma City

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.
