A liquid membrane is a liquid coating applied to a surface to form a waterproof barrier. This solution forms a continuous film, providing protection against water infiltration, leaks and moisture damage. It is often used in the construction industry to waterproof roofs, foundations, terraces and other structures, providing durable, flexible protection against the elements.

For over a century, SOPREMA has deployed its expertise to develop a range of high-quality products that meet the most demanding standards in the construction industry.
