Composite waterstop HYDROSTOP

thermoplasticelastomerfor foundation

Overview
Pre-formed composite collars with an elastomeric, hydro‑expansive structure designed to provide dynamic sealing and full waterproofing of service penetrations and construction joints in critical wet areas such as showers, terraces and swimming pools. Compatible with 6D membrane systems and next‑generation polymer gels.

Product description
HydroStop is a tape and collar system manufactured from specially modified hydro‑expansive thermoplastic elastomers. It expands reversibly to adapt to the available cavity volume and maintain a durable seal, unlike traditional sodium bentonite solutions. Suitable for both temporary and permanent contact, including chlorinated water, the material is engineered to seal joints between foundation slabs and perimeter walls in concrete pools and to close service penetrations in damp environments.

Applications

• Dynamic sealing and waterproofing of service penetrations (showers, terraces, swimming pools)
• Waterstop between foundation slab and perimeter walls in concrete swimming pools
• Waterproofing of joints, corners and edges in damp indoor and outdoor areas
