TrenchLock Kit

TrenchLock is the first product of its kind – ever! It makes TrenchDrain WaterGuard air tight. Water can go down, but air can’t come up. This will stop radon gas, its primary use. It will also stop humidity and odors, when they are a concern, and can even stop cold air from coming into the basement when there is a connection to an outside drain of some kind. Simply cut the sections to length, insert into drain sideways and rotate 90 degrees. Then, caulk the sides, drop the balls in, and pop on the trench drain grate.
