How French Drains Work

French drains, named after their inventor Henry French, provide a reliable solution for draining excess water from your yard. A French drain is essentially a gravel-filled trench with a perforated pipe at the bottom. The pipe collects water and directs it into a drainage ditch or street, away from your property.

To install a French drain, an experienced outdoor contractor should be hired to ensure it is done correctly. Improper installation can lead to further water problems, so it’s essential to seek professional help. Once installed, the French drain effectively diverts groundwater away from the perimeter of your house, preventing potential damage to your foundation.

The drain is installed on a slope to ensure water flows away from the house. It is buried about two feet deep in a gravel trench approximately eighteen inches wide. Proper grading of the landscape around your house is also important to prevent foundation water damage. By ensuring water flows away from your house, you can avoid chronic wet areas that may lead to foundation damage, especially during freezing temperatures when water absorbs into the foundation and expands.

  • Hire an experienced outdoor contractor to install a French drain
  • Ensure proper grading of the landscape around your house
  • French drain prevents potential damage to your foundation

Other Drainage Solutions: Surface Regrading And Retaining Walls

While French drains are highly effective, there are alternative methods that can be employed to fix drainage problems in your yard.

Surface regrading is the process of altering the natural slope of your yard to encourage proper drainage. By reshaping the terrain, water is directed away from your house and other landscape features, preventing water accumulation and subsequent damage.

Retaining walls, on the other hand, can be strategically placed to control the flow of water in your yard. These walls separate areas of different elevations, preventing excess water from draining onto lower sections. By providing a barrier, they divert water away from vulnerable areas and ensure proper drainage.

It’s important to assess your specific drainage issues and consult with a professional to determine which solution is best suited to your needs.
