• Water Collection: The perforated pipe in the French drain allows water to enter, while the gravel or NDS foam surrounding the pipe filters out debris.
  • Flow to a Drainage Point: The water is then directed through the pipe to a designated drainage area, such as a dry well, storm drain, or a sloped area of your yard.
  • Prevents Erosion: By controlling water flow, French drains help to prevent soil erosion and protect the integrity of your lawn.
