High quality for consistent safety
Keep your home dry. A well-protected and dry cellar is the best guarantee for the upkeep and protection of the building substance, keeps moisture away from masonry, protects against mould and rising damp and prevents may other problems. The first step is the effective and permanent protection of the foundation walls which should be made right during the building stage. Dimpled membrans made of special strong and robust plastic material have proven to be the best solution. But not every brand of dimpled membrans is as good as the next: there are substantial differences in terms of strength, stability and material finish. It pays to take a closer look and to opt for a high-grade material – your home will forever be grateful.

How do dimpled membrans work?
When it comes to protecting the foundation walls, dimpled membrans are unbeatable: they combine ultimate pressure resilience under a wide variety of different conditions with a sealing effect for the foundation walls. They keep the building dry and are shockproof and fracture resistant. 

When selecting dimpled membrans, properties such as abrasion resistance, resistance to chemicals and protection against fungi and bacteria should also be kept in mind to ensure that the dimpled membrans do their job properly for many years to come. They are not only a valuable asset when it comes to waterproofing the cellar. They also serve as cleanliness layer or as drainage for green roofs.

Ultimate pressure resilience
It pays in the long run to decide in favour of dimpled membrans with high-grade material properties. It is often the less obvious details which are crucial for the proper function, for instance a strongly enhanced pressure resilience. A special star-shaped design of the dimples enhances resilience and stability even more, resulting in the forces being better absorbed and the mechanical durability being increased.
