Interior & Exterior French Drain Installation

Water problems in your basement or yard can lead to serious structural damage, mold growth, and costly repairs. A professionally installed French drain system is one of the most effective ways to protect your home from water intrusion.

We specialize in both interior and exterior French drain systems, providing long-term waterproofing solutions that keep your foundation dry and your property protected.

What Is a French Drain?

A French drain is a trench filled with gravel and a perforated pipe designed to redirect groundwater away from your home. It collects excess water and safely channels it away from your foundation, preventing flooding and water damage.

French drains are ideal for:

• Basement water intrusion
• Yard drainage issues
• Foundation protection
• Crawl space moisture control
• Surface water pooling

Interior French Drain Systems

An interior French drain is installed along the perimeter of your basement floor, just inside the foundation walls. It captures water as it enters and directs it to a sump pump system for removal.

How It Works:

1. A trench is cut along the inside perimeter of the basement.
2. A perforated drainage pipe is installed.
3. The trench is filled with gravel for filtration.
4. Water is directed to a sump pump basin.
5. The system pumps water safely away from your home.

Benefits of Interior French Drains:

• Stops basement flooding
• Controls hydrostatic pressure
• Prevents mold and mildew
• Minimally disruptive installation
• Cost-effective waterproofing solution

Interior systems are ideal when excavation outside the home isn’t practical or when water is entering at the foundation footing level.

Exterior French Drain Systems

An exterior French drain is installed around the outside perimeter of your home’s foundation. This system prevents water from ever reaching your basement walls.

How It Works:

1. Soil is excavated around the foundation.
2. Foundation walls are inspected and sealed.
3. A perforated drain pipe is installed at the footing level.
4. Gravel and filtration fabric are added.
5. Water is redirected away from the home.

Benefits of Exterior French Drains:

• Stops water before it enters
• Protects foundation walls
• Reduces long-term structural damage
• Ideal for new construction or major renovations

Exterior systems are often the best long-term solution for homes experiencing consistent groundwater issues.
