Perimeter Drainage: Intercept Water Before It Reaches Your Foundation
Perimeter drainage systems (French drains) are installed around the exterior or interior of your foundation to collect and redirect groundwater away from your home.
A perimeter drainage system, commonly called a French drain, is a gravel-filled trench with a perforated pipe that collects groundwater and redirects it away from your foundation. When installed correctly, it is one of the most effective ways to reduce hydrostatic pressure and prevent water intrusion.
Exterior perimeter drains are installed at the base of your foundation footing and route water to a downhill outlet or sump. Interior perimeter drains run along the inside base of the wall and direct water to a sump pump.
In Colorado, perimeter drainage is often part of a comprehensive waterproofing plan that may also include sump pumps, vapor barriers, and grading corrections. We assess your specific situation and recommend the combination that provides the most reliable, long-term protection.
