Ethylene vinyl acetate terpolymer (EVA) triple-layer, double-sided non-woven fabric waterproofing membrane for cavity wall construction

Advantages:

• Triple-layer, 1,2 mm thick DIN-compliant and bitumen-compatible damp proof course – elastic and watertight. It meets the requirements of DIN EN 14909, DIN V 20.000-202 and DIN 18533
• The double-sided non-woven fabric enables an excellent connection to the masonry mortar, thereby ensuring high shear strength in the masonry
• The membrane boasts extreme tear strength – longitudinal > 600 N / 5 cm to transverse > 450 N / 5 cm.
• only half as heavy at the same thickness as other commercially available 1,2 mm PVC damp proof courses
• Resistant to rising moisture and rot-proof, securely protecting the masonry from the ground up
• Used as a horizontal barrier layer installed in the lowest horizontal joint of the masonry between two mortar layers and can also be used as an L- or Z-barrier in a cavity wall. It can also be used in the area of wall openings, such as window openings, lintels or balustrades
• Easy and efficient to install and is easy to cut from the 25 m long roll
• UV-stabilised and retains its flexibility at all temperatures
• Can be glued with elastic glue for waterproofing membrane (ALB-GLUE-WM/310)

Installation:

• The waterproofing EVA membrane is laid in one layer.
• The surface must be levelled out using Group 2 or 3 mortar acc. to DIN 1053 in order to obtain an even surface
• Then fit the membrane into the horizontal joint between two mortar layers on the base slab
• At the joints, a sufficient overlap of 20 cm must be ensured
• The width of the damp proof course must be selected so that no moisture bridges can form to the side of the bricked-up wall
• As an L-barrier in a cavity wall, the membrane is glued to the rising masonry with elastic glue
• As a Z-barrier in a cavity wall, the membrane is fit into the shell masonry, then later inserted into the facing shell
