A specifically designed PVC high performance waterstop
suitable for both internal and external use. Specifically
developed to seal joints (watertight) in concrete structures
which protects the reinforcing steel against corrosion attack.
Swelling external high-pressure seal for distance tubes.
The Active Ring mini/maxi, made of TPE (thermoplastic
elastomer), is used for a simple and reliable external
waterproofing of plastic and fibre cement distance tubes.
The swelling and the swelling pressure that forms during
the swelling process prevents the ingress of water.
