PENTAFLEX^® is the name for a range of products which are used to fabricate completely waterproof structures (waterproof concrete). The PENTAFLEX^® elements are fully covered on both sides with a special coating. The connection between the special coating and the fresh concrete reliably prevents the joint system from being undermined.

A concrete cover of 30mm is sufficient to withstand a water pressure of 5.0 bar (2.0 bar according to the General Appraisal Certificate). The enormous elasticity of the coating in the area of the joint prevents any leaks that could be caused by shrinkage of the concrete.

Reliable sealing fully compliant with the German directive on watertight concrete
