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.

Having an anchoring depth of 30mm, PENTAFLEX^® is approved up to 5.0 bars. According to the general appraisal certificate only 2.0 bars are approvable. This corresponds to a 2.5 times security on the proof pressure. Exempt from that is the product PENTAFLEX KB^® 80, which is generally only approved with a maximum of 1.0 bar, due to its smaller construction height < 120mm. 

Reliable sealing fully compliant with the German directive on watertight concrete
