A significant amount of the water in this basement flowed in through the door to the yard. To remedy this, our team installed our TrenchDrain system. The distinctive grate that covers Trench Drain tells you exactly how it works. This innovative drain is installed flush with a concrete floor; you can walk right over it. But the grated top will capture surface water before it can get where it doesn’t belong. Trench Drain interlocks perfectly with WaterGuard drainage channel, but it can also be used with other drainage pipe.
