If your property experiences significant groundwater issues or poor drainage around your foundation, a French drain system can be an effective solution for preventing water from entering your crawl space. A French drain is a trench filled with gravel or rock that contains a perforated pipe. This system is installed around the perimeter of your foundation to collect and redirect groundwater away from your home. By intercepting water before it can reach your foundation, a French drain helps to keep your crawl space dry and prevents potential water damage.
