Abstract

The invention proposes a waterproofing membrane that ensures superior thermal adhesion and environmental compatibility using recycled polyolefin. The waterproofing membrane consists of a polyolefin membrane containing recycled polyolefin and is characterized by the fact that the recycled polyolefin contains impurities incompatible with polyolefin in amounts ranging from 1 to 20% by weight, and the impurities have a maximum size from 1 to 2000 μm.
