Wecryl GM Roof Waterproofing System

Brief description

The Wecryl GM roof waterproofing system is the low-odour version of WestWood's extremely durable and high-quality flat-roof waterproofing system.

A key feature is that it creates a seamless waterproofing membrane that can incorporate even the most complex roof penetrations, rendering them permanently waterproof. In addition this system is extremely weather-resistant, crack-bridging and flexible at low temperatures. Due to its low-odour formulation, it is used for odour-sensitive areas.

Areas of application

The Wecryl GM roof waterproofing system is used for the highly durable waterproofing of flat roofs, especially in odour-sensitive areas. Its advantages are particularly evident whenever a secure waterproofing system with a long service life is desired and where reduced odour nuisance is required during application.
