Waterproofing membrane based on bitumen modified with polymers containing hollow glass microspheres.

摘要

Disclosed are waterproofing membranes consisting of a backing impregnated with a bituminous formulation comprising industrial bitumen, a mineral filler, a thermoplastic polymer or a mixture of thermoplastic polymers, characterised in that the mineral filler consists of hollow glass microspheres with a density of between 0.10 and 0.14 g/cm 3 and a size of less than 120 µm.
