Wecryl Roof Waterproofing System

Brief description

The Wecryl roof waterproofing system is specifically designed as a highly durable waterproofing system for flat, non-used roofs.

Since it is applied as a liquid, it creates a seamless waterproofing system in which even the most complex roof penetrations can be reliably and durably incorporated. It is also extremely weather-resistant, crack-bridging, flexible at low temperatures and its surface can be finished in any desired colour.

Areas of application

The Wecryl roof waterproofing system is used for creating a highly durable waterproofing membrane on non-used flat roofs in new build developments and for refurbishment. The system is suitable for residential, commercial and industrial properties or for garages – wherever secure waterproofing with a long service life is desired.
