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.
