Your home’s perimeter drainage system is perpetually working to remove rainwater and keep your home dry. The rainy season guarantees your drains are working hard. 🌧💪 A perimeter drain, or weeping tile, is a perforated pipe that allows water to enter and to be drained away from the foundation of your home. A blockage of dirt or roots can cause water to seep into your basement wall, so the best thing to do is to perform a camera inspection and discover problem areas early on.
