The alwitra contribution not just for a good climate on the construction site: EVALASTIC® waterproofing membranes are special EPDM membranes combining the requirements for a high-quality, long-term reliable roof sealing with the ecological advantages of synthetic and rubber technology. The specific material properties allow for easy, flexible and precise application through homogeneous material welding with standard hot-air welding devices. A clean job!

Variants and accessories
Polyester fleece backing as a compensation layer - perfectly suited for mechanical fastening or bonding with alwitra adhesive.
EVALASTIC® VGSK waterproofing membranes are based on our long-term proven EVALASTIC® waterproofing membranes. Additionally, the membranes have a glass/polyester fleece backing and a synthetic adhesive compound coating. After laying, the fleece backing also reduces stress and strain on the system (vapour decompression, movement compensation, etc.). The coating is bitumen-free and solvent-free and covered with a protective film when delivered. Product and system audits are carried out according to the requirements of the European standards DIN EN 13956 and DIN EN 13967 and provid e the basis for the entitlement to CE marking.
EVALASTIC® VGSK waterproofing membranes are 25 m long, 1.05 m wide and produced with a non-coated welding edge on one side. Thus, a homogenous welding in the seam area is ensured.
EVALASTIC® VSKA tapes are membrane tapes (thickness of waterproofing layer 1.5 mm) based on the long-term proven EVALASTIC® waterproofing membranes. Additionally, they are equipped with a polyester fleece backing and a synthetic adhesive compound coating. After laying, the fleece backing also reduces stress and strain on the system (vapour de- compression, movementcompensation, etc.). The coating is bitumen-free and solvent-free and covered with a protective foil when delivered.
The application of EVALASTIC® standing seam effect profiles is as easy and safe as for all alwitra waterproofing membranes. Both waterproofing membrane and profile perfectly adjust to the given roof structure. Installation is also possible on lowsloped roof areas. This is, where other waterproofing types meet their limits. Upon request, the EVALASTIC® standing seam effect profile may also be retro-fitted.
EVALASTIC® maintenance walkway tiles are used to mark the inspection and maintenance walkways (also provides additional protection for the waterproofing) on flat roofs covered with EVALASTIC®. The textured surface provides a strong grip, even on sloped and wet areas.
