30 Year Warranty

STOPAQ meets all factors that are necessary for a long term corrosion protective life span. Although other conventional materials are also good materials to serve as corrosion protection, they also show some disadvantages, for instance tear formation due to ageing and an adhesive failure mechanism leading to a reduction of the protective life span.

By the combination of the basic properties of the visco-elastic corrosion prevention and the additional layers of mechanical protection such as PE-backing foil, the corrosion protective life span can easily be guaranteed for 30 years. This is based on theoretical stability of the concerning polymers and on experience with actual subterranean applied materials.
