French Drains: Why They Are Important

G.L. Hunt is the expert foundation company that Texas relies on for stability. Read on to learn about French drains and how they can help keep your foundation stable for years.

What Are French Drains?

A French drain is an underground drainage system designed to remove excess moisture from the ground and prevent it from causing damage to structures. Contrary to what the name suggests, French drains did not originate in France. Instead, they were named after Henry Flagg French, an American who introduced this drainage solution in the 1800s to address issues caused by excessive groundwater.

French drains are typically installed near building foundations but can be used in various other locations as well. The system consists of a trench filled with gravel or rock, a perforated pipe and a filtering mesh that work together to collect and redirect water away from the area.

How Do French Drains Work?

The science behind a French drain is simple yet effective. Water naturally follows the force of gravity, so the drain is positioned just beneath the ground’s surface to guide water away from vulnerable areas.

The perforated pipe — surrounded by rock material and a filtering mesh — creates a pathway that ensures only water enters the pipe, leaving debris and soil behind. The slight slope incorporated into the trench directs the water to a safe location, such as a drainage ditch or a dry well.

French Drain vs. Surface Drain: Which Is Right For You?

Understanding the difference between a French drain and a surface drain is crucial for addressing specific drainage issues. While French drains are installed underground and are ideal for managing groundwater, surface drains are placed on top of the ground to collect and remove surface water from areas prone to pooling, such as driveways or patios.

Choosing between a French drain and a surface drain depends on the source of your water problem. If groundwater is seeping into your basement or causing foundation issues, a French drain is likely the better option. A surface drain may be more suitable for managing rainwater runoff or preventing surface water from flooding specific areas.

How Deep Does A French Drain Need To Be?

When installing a French drain, getting the depth right is key. Typically, these drains are set at a depth of 18 to 24 inches, but this can vary depending on the specific needs of your property. The goal is to place the drain deep enough to catch water before it reaches your foundation, but not so deep that maintenance becomes a hassle. 

If you’re unsure about the right depth for your situation, it might be best to consult a professional on our team to ensure your drain works effectively.

Can I Install A French Drain Myself?

While it’s possible to install a French drain yourself, it requires careful planning, proper tools and a good understanding of your property’s drainage needs. While DIY installation can be a cost-saving measure, it comes with risks. 

Incorrect installation could lead to inadequate drainage, persistent water issues or even damage to your property. For these reasons, many homeowners opt to hire professionals to ensure the job is done correctly.
