The Role of a French Drain
A French Drain serves as a critical component of home water management by channeling water away from your home’s foundation. This system is particularly effective in preventing groundwater and surface water from penetrating or damaging your basement walls. It is an underground system that intercepts water before it can reach your home, redirecting it safely into the surrounding landscape or a drainage system.
