Sub-slab depressurization and Radon mitigation
Check out the new publication from the GeoCalgary2002 conference on the use of multi-linear drainage geocomposites DRAINTUBE® as part of the sub-slab depressurization system providing separation and gas collection functions. The geocomposite is connected to a collector pipe and to the gas pit. It collects the soil gas and reduces the head losses thanks to the high-density network of perforated mini-pipes into the product and the specific fittings used to connect the product to the main collector pipe. Multi-linear drainage geocomposite has been found efficient for both passive and active SSD systems.
