Why Should You Install a French Drain


If you have water drainage problems on your property, a French drain is an effective and straightforward drainage system that can help rid your property of excess water. Knowing what a French drain is and how it works can help you decide whether or not this type of drainage system is right for your home.

What is a French drain?

A French drain is a pipe placed in the ground to collect rain water. French drains are often used in yards and in basements that have drainage problems. French drains are used to transport excess water to low lying areas where the water will do no damage.

How does a French drain work?

A French drain usually consists of a wide pipe perforated with holes that has been buried in the ground. Usually French drains are angled downward to keep water rolling through the pipe. To enable water to flow through the ground to the drain, gravel is placed on top of the pipe, because water flows through gravel more easily than soil.

Who can benefit from a French drain?

French drains are an effective solution on properties that have chronic water drainage problems. Your property may benefit from a French drain if:

  • the soil is often soggy and standing water is common.
  • the basement floods regularly.
  • your yard includes a retaining wall on a hillside.

What are the advantages of a French drain?

If you’re thinking about getting a French drain installed on your property, you’ll want to know what makes a French drain better than other drainage options. Some of the advantages of this type of drain include:

  • French drains have no moving parts, which can make them less likely to break down or stop working.
  • If installed properly by a qualified plumber, a French drain can last for a very long time.
  • In some circumstances, shallow French drains can be easy to install as a DIY project.

What are the disadvantages of French drains?

Although French drains have many good qualities, they are not entirely without issues. For example:

  • Because they’re buried in the ground, French drains can be difficult to repair when they develop problems.
  • French drain installation, if placed deep in the ground around pre-existing structures, can be expensive.

If you’re thinking about installing a French drain, what should you do to get started?

Before a French drain can be installed, the exact path for the drain must be planned. The drain must run through the areas where water is the most problematic while avoiding exterior water pipes and sewer channels. The exit point of the French drain should be a sunny, low-lying area. The exit should be directed away from any neighboring properties to avoid flooding someone else’s property. Work with your plumber to plan a sensible path for your French drain.
