Waterguard Sub-floor basement drainage channel. 2x3'9" lengths. Because the Waterguard channel sits above the footer it will not block with dirt and silt like a drain tile system can. Waterguard has a special flange which allows water to be collected from the face of the foundation wall and directs it into the channel below floor level so water will never run down the wall and onto the floor. DIMENSIONS. This listing is for 7' 6"ft Waterguard channel consisting of two lengths each 3' 9" long. 4.1/4" high - including the flange and approx. 4" wide.  A full range of accessories are available and these have been improved over the Basement System' ones, they include Waterguard corners , Waterguard Drain outlets and Waterguard Inspection ports (aka cleanouts).  We also have a flangeless version of Waterguard , with its own accessories, please note that the Waterguard accessories are not interchangeable between the Waterguard channel with the built in wall drain and the flangeless channel.  If you are ordering the flangeless Waterguard channel you should ensure that you order the flangeless Waterguard accessories which include, Waterguard flangeless drain outlet , Waterguard flangeless corners , Waterguard flangeless inspection ports .
