WPA BM70
New Generation Bentonite Membrane
WPA BM70 is designed to waterproof below-ground structures, preventing water ingress and protecting the structure against contaminated soils.
WPA BM70 is fibre-reinforced by needle-punching the composite across the entire surface area of the product.
Unique to this product, the high-tenacity fibres are then thermally locked to ensure the product’s high long-term shear strength and selfconfining properties.
