How to Create a French Drain

Step-by-Step Guide: Creating Your Own French Drain

A French drain is a type of drainage system that is used to redirect water away from an area. It is commonly used to prevent water from entering basements or to divert water away from a building's foundation. French drains are relatively easy to install and can be done by most homeowners. Here is a step-by-step guide on how to create a French drain:

Step 1: Determine the Location of the Drain

The first step in creating a French drain is to determine the location of the drain. This will depend on the area you want to redirect water from. You should choose a location that is downhill from the area you want to drain.

Step 2: Dig the Trench

Once you have determined the location of the drain, you will need to dig a trench. The trench should be approximately 18 inches deep and 12 inches wide. You can use a shovel or a trenching machine to dig the trench.

Step 3: Add Gravel to the Trench

Once you have dug the trench, you will need to add gravel to the bottom of the trench. The gravel should be approximately 2 inches deep. This will help to create a base for the drain.

Step 4: Add a Perforated Pipe

Next, you will need to add a perforated pipe to the trench. The pipe should be placed on top of the gravel. The perforations in the pipe will allow water to enter the pipe.

Step 5: Cover the Pipe with More Gravel

Once you have added the perforated pipe, you will need to cover the pipe with more gravel. The gravel should be approximately 4 inches deep. This will help to create a drainage bed for the water.

Step 6: Cover the Gravel with Landscape Fabric

After you have added the gravel, you will need to cover the gravel with landscape fabric. The landscape fabric will help to prevent soil and debris from entering the drainage system.

Step 7: Cover the Landscape Fabric with Soil

Finally, you will need to cover the landscape fabric with soil. The soil should be level with the surrounding area. This will help to ensure that the drainage system is not visible.

In conclusion, creating a French drain is a relatively simple process that can be done by most homeowners. By following these steps, you can create a drainage system that will redirect water away from your home or building.
