French Drainage System

French drainage system is a method of moving water in a interior or exterior drainage area that can collect water and move it to an area where it can be dispersed. This age-old methodology, can be useful for both flooded basement problems, or exterior drainage problems. Fairfax Contractor utilizes French drain system in many of our interior and exterior projects. Water, be it present in your basement foundation, or your yard is constantly looking for the path of least resistance. What a French drain does is diverts water through a system that is made up of three components. The first component in a French drain system is to install a PVC pipe that is manufactured with holes installed the pipe. These pipes are installed so that they have a slope of at least a quarter of an inch per foot to move the water. The PVC pipe is wrapped with a fiber cloth so that it is not become contaminated by settlement. With the excavation set at the approximate grade to move the water, it is encased with #57 gravel. Basically gravel acts as a sponge to collect the surrounding water diverting it into the PVC pipe so that it can be evacuated to the area desired. A French drainage installtion can be used in extior drainage, and in the interior of your basement.

Exterior French Drain Systems


If you’re homes experiencing exterior drainage problems one of the best solutions is a French drain. The topography of your lot may not allow the water to drain properly in flat areas. Utilizing a French drain may be able to move water, and problem areas without a natural grade. For example you have one particular area in your yard that is completely flat, yet the grade suddenly is sufficient to move storm water effectively. Installing a French drain will soak up the water like a sponge in the area that is flat and effectively move it to an area where the water can be naturally be removed by means of gravity.

Interior French Drain Systems

In most Northern Virginia homes interior French drain systems were not installed in homes built before 1985. Though your builder may have installed drainage pipes on the exterior of the home, they were typically ineffective in reducing hydrostatic pressure on the basement walls. If your basement is continually, it may be time consider installing a interior French drain. A French interior drain can be very effective to alleviate a flooding basement or crawl space. In older homes, Fairfax Contractor can design a interior French drain system that will alleviate almost all flooding problems you may be experiencing. Our French drain systems, have two main properties. One is a perforated PVC pipe that is installed around the interior perimeter of your basement, the second is a sump pump crib that will evacuate the water via a sump pump.
