Abstract

Relates to Wykamol CM8 Geotextile Membrane, a high-density polyethylene (HDPE) membrane with geotextile backing, for damp-proofing walls below ground level and floors in new construction or in existing buildings.

Key factors assessed were mechanical resistance and stability, safety in case of fire, hygiene, health and the environment, safety and accessibility in use, protection against noise, energy economy and heat retention, sustainable use of natural resources, and durability.
