A French drain is a trench filled with gravel or rock or containing a perforated pipe that redirects surface water and groundwater away from an your home or area that you choose. A French drain can have perforated hollow pipes along the bottom to quickly vent water that seeps down through the upper gravel or rock. French Drains are primarily used to drain groundwater from gardens and around the foundations of buildings. French drains are designed to move water that is trapped in the ground away or towards an area. They are best used in soil that is prone to frequent saturation from rain or flooding, learn more from this Drain Cleaning Company.

Properly constructed, french drains will work well to transmit water from the pipe to the exit of the pipe; however, they are not very efficient in dewatering poorly drained soils. Adequate fall means at least 2 ft lower per 100 ft of pipe or 0.25 in. per foot of slope.

French drains are primarily used to prevent ground and surface water from penetrating or damaging building foundations. Alternatively, French drains may be used to distribute water, such as a septic drain field at the outlet of a typical septic tank sewage treatment system. French drains are also used behind retaining walls to relieve ground water pressure.
