ProtectoWall & Pro-Drain 8 Waterproofing System
Description

ProtectoWall is a self adhesive damp proof membrane (DPM) designed to be applied to the exterior face of basement and below grade foundation walls from moisture and vapour transmission. Pro-Drain 8 is a dimpled sheet product developed specifically for below ground waterproofing protection.

ProtectoWall is cold applied peel and stick membrane consisting of a tough fabric reinforcement laminated between two layers of SBS modified rubberised asphalt. ProtectoWall is tacky on both sides of the membrane providing excellent adhesion onto both the substrate and on to itself at laps and also for holding the Pro-Drain 8 in place.

Pro-Drain 8 is black in colour and manufactured from High Density Polyethylene (HDPE). The sheet thickness is 0.6 mm with a dimple height of 8mm. Pro-Drain 8 is available i  2.1 x 1.2m (2.52m²) sheets.
