CAVITY DRAINAGE MEMBRANE
Orchard Preservations basement waterproofing experts install a tanking membrane. This membrane has an air gap behind it that makes it act like a dry lining to your walls, floors, and ceiling. This makes it possible for water to be evacuated outside the building. All tanking membrane junctions and joints are designed with the objective of removing all the water behind the membrane. This is done either through a pump installation or natural drainage.
The first task involves the installation of a cavity drainage channel around the room’s edge and bedding it into a rebate at the junction of the floor and the wall. The next task involves fixing the membrane to the walls using waterproofing plugs and then laying the membrane over the floor. The junction between the floor and the wall is sealed using a corner tape, thereby creating a complete seal from any form of water ingress. After membrane installation, the next part of this important process is securing the internal walls of your room. Your internal wall finishes can either be plastered directly onto the membrane or you can use a plasterboard dry lining system.
