Soprema was founded in 1908 and has remained independent throughout its history.

Soprema’s founder, Charles Geisen, was the inventor of the Mammoth Membrane, which was a catalyst for modern waterproofing membranes.

The current Soprema Group chairman, Mr Pierre-Etienne Bindschedler, is the third generation of the founding family.

Soprema has established itself as a world leader in the development and manufacture of waterproofing membranes. As a testament to the company’s growth, Soprema now has 14 full-time production plants, with subsidiaries and distributors covering 80 countries and 5 continents.
