French Drain Installation

An exterior French drain is a waterproofing system installed outside the foundation of a building. It consists of a trench filled with gravel and a perforated pipe, covered with a geotextile membrane to prevent clogging. The system includes a double-wall membrane for enhanced protection: one layer is a liquid membrane that prevents water from penetrating the concrete foundation wall, reducing humidity buildup inside the house and preventing further damage to the foundation. The second layer is a drainage board, which channels water efficiently to the drain at the bottom of the trench. This system directs water away from the foundation, safeguarding against infiltration and structural damage for many years to come. At Bon-Drain, we prioritize durability, efficiency, and tailored solutions to ensure our clients’ long-term peace of mind.

French Drain Installation

An interior French drain is a waterproofing system installed along the inside perimeter of a foundation wall. It is designed to capture and redirect water that infiltrates through the walls or seeps up from beneath the foundation. The system consists of a perforated drain pipe laid in a trench at the base of the foundation footing, covered with gravel and protected by a geotextile membrane to prevent clogging.

In addition, a wall drainage system, such as a drainage board, is installed to guide any moisture on the walls directly into the drain pipe. The collected water is then directed to a sump pump, which safely discharges it away from the property. This ensures a dry, usable basement space while preventing water damage and mold growth.

At Bon-Drain, we prioritize efficiency and long-term reliability. Our interior French drain system is ideal for homes with water infiltration issues, especially where exterior obstacles make exterior drains impractical. By choosing Bon-Drain, you are investing in a durable solution to protect your home and preserve its structural integrity.
