Prefabricated waterproofing membrane composed of distilled bitumen and elasto-plastomeric polymers (APP type) with composite non-woven polyester fabric reinforcement that gives the membrane a very good dimensional stability (0.3%). For elasto-plastomeric membranes without mineral self-protection consisting of slate, intended to be used as a top layer, always provide for periodic surface protection with protective reflective paint. On request, the product can be finished on the surface with non-woven polypropylene fabric. 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:

• High dimensional stability
• Good mechanical performance
• The PP finish allows for immediate anti UV coating if required
