The market now offers a wide range of waterproofing membranes, the choice of sub-structure waterproofing depends on many factors ...
Permanent water impermeability and the reliability of the system are important components. Our Zemseal® system offers double safety with dual-bond technology and protects waterproofing systems from water ingress.
The dual-bond technology secures a connection between the Zemseal® membrane with the concrete. The bond with concrete takes place in two different ways:
Mechanical bond with concrete
During the concreting process (vibrating and compacting), the fresh concrete penetrates into the coating of the Zemseal® surface and forms an excellent bond with the Zemseal® foil as the concrete hardens. The indented surface of Zemseal® strengthens the mechanical bond with the concrete structure.
Chemical bond with concrete
The outer-surface of the Zemseal® membrane is subjected to a special treatment during production, which changes the surface structure and thus increases cement adhesion to the membrane.
With Zemseal® you can rely on a product which has been extensively tested according to a recognised European test programme and guarantees high quality.
