DELTA®-MAUERWERKSSPERRE
The barrier against rising damp – horizontal masonry separation within the meaning of DIN 18533
DELTA®-MAUERWERKSSPERRE is a durable and highly flexible damp-proof course made of polyolefin. It will also serve as a moisture barrier under a wash floor. DELTA®- MAUERWERKSSPERRE is 0.4mm thick and easy to roll up and apply. DELTA®-MAUERWERKSSPERRE has a non-slip profile on both sides for optimum bonding with mortar. The sheet is bitumen-compatible, rot-proof, and UV-stabilized. It is highly flexible even at low temperatures, so that the sheet remains permanently free from cracks. DELTA®-MAUERWERKSSPERRE is installed in a single layer. Contact surfaces with mortar belonging to category II or III (DIN 1053-1) should be covered thickly enough to make a horizontal surface without irregularities. The sheet should be pressed firmly into the mortar. At joints, sheets should overlap by at least 20cm to ensure optimum protection from moisture. The sheet should be wide enough to rule out any chance of moisture bridges forming on either side of the rising wall.
