Cross-section of a french drain system — Houston area installations
Due to heavy seasonal rains and clay-rich soils, homeowners in the Greater Houston area frequently face standing water and foundation saturation issues. A professionally installed French drain is the most reliable solution for diverting excess groundwater before it causes structural damage or destroys your landscaping. These drains use gravity to safely move water away from the perimeter of your home by using a strategically placed trench system filled with clean gravel and perforated piping. Understanding the mechanics of slope, filtration, and discharge is essential when dealing with a boggy backyard in Piney Point Village or protecting a foundation in Montrose.

Our comprehensive FAQ guide addresses important questions about installation costs, material options such as SDR 26 PVC, and maintenance tips to keep your property dry and protected for decades.
