How can a French Drain help with drainage issues?





The installation of a French Drain is a low cost solution in preventing standing water at your residence. French Drains are a series of trenches filled with rocks or gravel, which are then topped with sand and turf. With the traditional design stated as being a gravel-filled trench, French Drains can include a drain pipe as well. This drainage system is used to protect the foundation of a house that is unable to drain properly and will be installed so that water drains to an area that can support the redirected water. French Drains are popular in Florida due to the combination of heavy rain falls and flat lands. Once that top layer of soil becomes saturated with water and the area is flat, it leaves the rainwater with nowhere to flow. With your new installation of a French Drain, it will allow the water and soil to move easily through the gravel and away from the problem area.

  1. Dig a trench: In order to install a French drain, you must begin by digging a trench. The depth and width may vary, but commonly it’s 5 to 6 inches wide and 8 to 12 inches deep.
  2. Proper grade: Having a proper grade/slope is critical for the water to accurately flow in the right direction.
  3. Fill with gravel: Add gravel to the existing trench leaving a couple inches between the gravel and the surface.
  4. Add sand: Lay at least 3 to 4 inches of coarse sand on top of the gravel which will allow the water to properly drain through.
  5. Add turf or sod: You may add turf or sod on top of the sand. If you choose sod over turf, be sure to wash the soil from sod roots preventing contamination of the sand with finer soil.
  6. Add a perforated drain pipe (for more severe drainage issues): Adding a perforated drain pipe is a similar process as noted above. You will first place an inch or two of gravel at the bottom of the trench, and then lay the drainage pipe, which should be wrapped in a filter fabric to prevent soil from clogging your pipe. Once pipe is properly placed, fill in the remainder of gravel around the pipe with at least 1 to 2 inches of gravel on all sides. You may need access to the pipe in the event that it becomes clogged.
