Besaflex (PVC-P)
Besaflex waterstops made of plasticized PVC are distinguished by numerours of good characteristics and high economic efficiency.
Plasticized soft-PVC has been in use since the 1930s and is subject to constant monitoring. This material was not used for waterstops until all its positve characteristics, especially its restistance to ageing, had been scientifically verified.
Meeting all normal requirements, Besaflex waterstops are up to most structually imposed strains.
They are resistant to acid and alkaline solutions and decay as well as to all naturally occuring agents.
The large number of different Besaflex profiles guarantees permanently groundwaterproof construction and expansion joints without the reinforcement system being affected.
