alwitra, leading specialist for high-quality flat roof waterproofing systems

The product range comprises superior roofing and waterproofing membranes EVALON and EVALASTIC as well as unique aluminium profiles for edge trims and further accessories such as rooflight systems, roof drainage elements and many more. 

We are the only manufacturer to provide all waterproofing components by way of an integrated system solution from a single source – thanks to our 2 German plants located in Trier and Hermeskeil. 


All alwitra waterproofing products share a common feature:  At the flashing area, they are equipped with a flashing strip/tape/connecting flange made of the same material as the waterproofing membrane itself, making for a reliable and homogeneous flashing against the waterproofing membranes. 

This is the perfect system solution for both quick and easy application and long-term reliability.

We aim to ensure our customers’ satisfaction. To achieve this, we believe in consistent customer orientation, employee enthusiasm, continuous innovation, sustainability, and commitment.
