DryZone uses several "extras" when installing a WaterGuard system on Delmarva. The first thing that we do is to wash the area down after the floor is jackhammered. This removes most of the concrete dust so it doesn't clog up the pipes. Next comes the CleanSpace wall liner. The white plastic you see on the walls is put there to prevent a wall crack from springing a leak and missing the drain. If a crack leaks towards the bottom of the wall, it will drip down the back of the liner and into the pipes. Another advantage to WaterGuard is the drainage ports. The corner of the two sections of WaterGuard is actually an inspection port. You can lift up the cap and flush the whole system out if you see dirt building up.
