The protection in new constructions against rising moisture is key to a long lifespan of walls. Installing a horizontal barrier underneath walls will prevent the future rising moisture due to capillary action, and the consequently damage caused by rising damp, salts, and efflorescence.

Horizontal Barriers are required to stop long-term damage caused by rising damp, salts, and efflorescence. Compared to post-installed systems, damp proof courses in new construction are economical and effective. Not only do these materials have to be waterproof, but they have to resist the pressure of the building. KÖSTER provides both elastic and rigid waterproofing products for this field of application.
