Prefabricated waterproofing membrane composed of distilled bitumen and plastomer polymer (APP) with rot-proof fibreglass mesh reinforcement with high dimensional stability. The self-protected version with slate chippings on the upper surface reduces the absorption of heat on the surface thus improving the durability of the membrane. The self-protected versions are provided with a lateral overlap.
Advantages:

• It allows to optimise the stability of waterproofing packages where the underlying seal is reinforced by non-woven polyester fabric.
