What is a French Drain?

A French drain is a trench covered with gravel containing a perforated pipe that redirects surface and groundwater away from an area. They are typically used to prevent ground water from damaging your home or business's foundation. French drains may also be used to distribute water, such as a septic draining at the channel of a typical septic tank sewage treatment system. They are also used behind retaining walls to relieve ground water force.

Why would you have one installed?

If you have a sub terrain basement or driveway, French drains could accommodate excess water build up and relieve your sump pump's work load, depending on your property's flooding history. French drains can help prevent:

  • Local Flooding: Unexpected flooding can be caused by sudden, locally heavy rain falls. Heavy downpours can bring severe water flood damage to a home, so you should call a professional to fix water damage right away.
  • Groundwater Leaks: Even during normal rainfall conditions where you think a house flood is not a threat, groundwater can find its way into a basement or crawlspace. Finished basements or bottom floors can be ruined by wet carpet, wood in crawlspaces can rot, mold and mildew spores can grow and odors can permeate the interior. When this happens, a homeowner needs a trusted contractor to fix water damage and manage the recovery process. Having professionals install French drains can help prevent such damage.
