Best in class – Quality & Performance

Our products are engineered and manufactured to the highest quality standards (in primarily Germany/Switzerland) and have been successfully used worldwide with zero product failures.

Independently Tested

Our products are independently tested with exceptional results (German Railway, Swedish Vattenfall, Kiwa accredited testing laboratory, SKZ accredited testing laboratory etc)

We’re greener

We’re green building certified (LEED, BREEAM, Nordic Swan Ecolabel) and our carbon neutral production facility is solar-powered and uses recycled rainwater to minimize our impact on the environment.

We lead through innovation

We only do Structural Waterproofing and where others are happy with good enough, we keep innovating to make waterproofing better, more durable, easier to install and more sustainable. In 2019 we were named one of Germanys Top 100 most innovative companies for the third time in four years (*BPA Gmbh).

Certified and accredited

We’re certified by many of the leading international standards including British, German and US/Canada (ICC-ES).

Over 20 years of excellence in waterproofing

We’ve spent the last two decades helping designers, specifiers and contractors select, design and install the optimal waterproofing for their projects.
