Mammouth and 1908 Conference Rooms

The roots of SOPREMA trace back to 1908 when Charles Geisen embarked on a quest to create waterproof fabric that was both flexible and easy to install. Through experimentation, he discovered that soaking jute fabric in hot bitumen produced a lightweight yet durable screed, which he named “MAMMOUTH®”. This innovative solution revolutionized the waterproofing industry, laying the foundation for SOPREMA’s legacy of excellence in construction materials. Today, MAMMOUTH and 1908 remain hallmarks of SOPREMA’s commitment to quality and innovation, embodying its rich history and enduring dedication to providing superior products and solutions for our customers.
