how a french drain works

When to Consider a French Drain


  • If experiencing problems with surface water, such as a soggy lawn or a roadway that washes out.
  • If water is getting into basements or below ground facilities.
  • To prevent water from building up behind a retaining wall on a hillside and undermining it.


A french drain is primarily used to prevent ground and surface water from penetrating or damaging building foundations. It is a trench filled with gravel or rock containing a perforated pipe that redirects surface water and ground water away from an area. French drains may also 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 often installed around a building foundation in two different ways:


  • Buried around the foundation wall on the external side of the foundation
  • Installed underneath the below ground floors on the inside perimeter
