5 Common French Drain Mistakes to Avoid When Installing Your Own Drainage System

A French drain system is a good idea for any homeowner to have in place. It can be installed at the lowest point on the property, and it will help prevent water from pooling around the foundation of your home.

If you have ever had a problem with your basement flooding, then you know that water can pool around your home’s foundation and cause major damage to your house. Installing a French drain system should be an easy and inexpensive way to keep this from happening.

French Drain Installation Mistakes to Avoid

French drains are installed to remove water from the ground. French drains consist of a perforated pipe that is laid in a trench and covered with gravel or crushed stone. They are often used as a preventive measure for basement flooding, which can happen when rain water runoff enters the building through cracks in the foundation and walls.

French drain mistakes to avoid include:

– Not following the local building codes for french drain installation

– Installing french drains too close to the foundation of your house

– Not providing enough drainage space around french drains

– Installing french drains in the wrong direction

– Not providing adequate drainage space for french drains to allow for proper flow

How Can You Spot a Wrongly Installed French Drain?

One of the most common problems with a French drain is that it was installed incorrectly. You can spot a wrongly installed French drain by looking for any of these signs:

– The French drain is not level with the ground and slopes down towards the house.

– There are gaps in the joints between sections of pipe.

– There are gaps in the joints between sections of pipe and where there are no gaps, there is a buildup of dirt or leaves.

– The pipe is not buried at least 18 inches deep like it should be.

Preventing Problems with Poorly Designed or Damaged French Drains

French drains are drainage systems that are designed to remove surface water and groundwater. They have been used for many years in Europe and the United States. They are typically installed in areas where there is a lot of rain and snowmelt, such as coastal regions or areas with a high water table.

French drains are installed on the perimeter of the property, surrounding the building’s foundation walls and beneath the footing. The drain pipe is buried underground near the foundation wall, then extends outward from the wall to cover an area about 1 ft (30 cm) wide. The length of pipe that extends away from the building should be at least 3 feet (1 meter) longer than its distance from the foundation wall.


French drains are an effective way of preventing water from seeping into your basement or crawl space. They work by collecting the water that runs off the ground and diverting it away from your home, thereby preventing flooding and foundation problems.
