Without proper drainage, water can seep into a home through doors and damage the interior. The TrenchLock drainage system was specifically designed to combat this problem. The TrenchLock is installed flush with the floor, to prevent tripping hazards. Its grated openings trap water as it comes into the house and redirects it to a sump pump system. However, in houses like this that have a radon problem, it is necessary to block the gases from leaking through the drain and into the home. The TrenchLock system includes balls of the right weight and size, which block gases from escaping through the holes in the drain when there is no water in the drain. When water flows, the balls float so water can drain.
