French Drains: Answering Your Questions

Preventing Water Damage to Your Basement and Landscaping

When it comes to managing water on your landscaping or protecting your basement and foundation from water damage, French drains are a popular solution. Here’s an easy overview of French drains, answering the most common questions homeowners have about them.

What are French Drains?

French drains are underground systems that collect and redirect groundwater and surface water away from specific areas, such as your home’s foundation. They are particularly needed in areas like Pennsylvania (PA), where heavy rainfall can saturate soil and lead to water damage in basements, crawlspaces, and around retaining walls.

Did you know that today’s French drains are an American invention?

Henry Flagg French was an Assistant U.S. Treasury Secretary and a lawyer with a keen interest in agriculture and drainage. He described the concept of these drains in his 1859 book, “Farm Drainage.” French’s advocacy and detailed descriptions helped standardize and spread the use of this method in America, hence the name “French” Drain.

How do French Drains Work?

A French drain consists of a trench filled with gravel and a perforated pipe. This design allows water to seep through the gravel, enter the pipe, and be channeled away from the foundation. The pipe’s perforations are designed to prevent soil and roots from entering the system, ensuring smooth water flow.

When are French Drains Necessary?

Installing a French drain is recommended or necessary in situations where water accumulation poses a threat to structures, such as when the yard slopes towards the home, causing water to pool around the foundation, or in areas prone to heavy rains that lead to soggy yards or flooded basements.

Inside vs. Outside French Drains: What’s the Difference?

Outside French drains are installed around the perimeter of a property to divert water away before it can penetrate foundations. Exterior drains may also be installed to prevent water pressure from damaging retaining walls. Inside French drains are installed beneath the basement floor to capture water that has already entered. The choice between them depends on your specific water management needs and the structure of your home.

How are French Drains Installed?

Installation involves digging a trench, laying a layer of gravel, placing a perforated pipe, covering it with more gravel, and then finishing the surface. The trench slopes downward to direct water away effectively.

Do I need a Permit for a French Drain?

This depends on your location. Urban and suburban areas may require a permit, especially if the installation affects stormwater runoff systems. Always check local regulations before starting.

How Long do French Drains Last?

Both interior and exterior French drains can last for many years, especially if the drainage trench is properly prepared, the drain itself is installed correctly, and attention is paid to nearby trees or shrubs that may invade the area of the French drain over time with their roots.

Interior French Drains may have an edge in longevity, because the soil around them is not exposed to weather patterns and erosion, and because they are most often out of the way of invasive root systems.
