Description: A conformable, swellable polymer/butyl rubber waterstop strip that expands in contact with water. When fully encapsulated by poured concrete, the expansive forces form a seal against concrete faces. The seal resists hydrostatic pressure, stopping water from entering sub-structures. ADCOR is a unique product that has been specifically developed to provide higher performance than conventional bentonite or swellable rubber waterstops. Superior performance arises from: controlled, reproducible, volumetric expansion cohesive strength maintained after volumetric expansion malleable and plastic, enabling easy application to a variety of concrete profiles GCP can also uniquely provide continuity of swellable waterstops at construction joint/movement joint intersections. This is achieved by linking ADCOR 500S with SERVITITE AT 200 co-extruded hydrophilic/PVC waterstops. Uses: Construction joints in in-situ concrete structures Casting new concrete against existing Floor slabs cast against diaphragm retaining walls, steel sheet piles and secant piled walls Joints between floor slabs and pile caps Pipe penetrations through floors and walls Remedial ‘breaking out’ of concrete Advantages: Controlled volumetric expansion – reduces risk of concrete spalling Conformable – can be installed onto a variety of irregular substrates Retains cohesive strength at both original and expanded volume No need for protective steel mesh Resists at least 6 bar (60 m) hydrostatic pressure. Volumetric expansion min 100% in cement water Simple overlap jointing on site Reproducible swell after wet–dry cycling Can be easily joined to GCP PVC waterstops at movement joints Unaffected by freeze/thaw cycling.
