A French drain is a type of drainage system that collects surface and sub-surface water. Typically, French drains in Dallas are installed around the foundation of buildings to prevent water from going underneath. They are also installed in areas that constantly remain wet even if it has not rained for days. If you are only having standing water issues after it rains,then you will not need a French drain; instead, you will need surface drains to collect the surface water. You can find our other type of drainage systems by visiting our drainage services page.Drainage Services
A deep trench needs to be dug in the problem area. If installing the French drain around the foundation of a building, the depth of the drain needs to be at least 5" below the foundation. This is to ensure no water can go under the building. The French drain consists of laying filter fabric in the trench, back filling the trench partially with gravel, installing a 4" S&D perforated pipe that is wrapped with fabric on the gravel and then back filling the rest of the trench with gravel. Gravel will be visible from the surface.
For most French drains in Dallas, a sump pump is required to expel the water to the desired location. The reason for this is the drainpipe is usually several feet below the surface of the ground and due to that,it does not provide enough “fall” to drain the water properly. Water cannot go against gravity by having the drainpipe pitch up towards the surface.
