Adcor® 500S - Hydro-expansive Waterstop
Verified by manufacturer 2 months ago
BBA Agrément Certificate
Certificate type
Hydro-expansive waterstop.
Application
Rubber hydrophilic waterstops suitable for:
- Construction joints for in-situ concrete structures.
- Casting new concrete against existing concrete.
- Floor slabs cast against diaphragm retaining walls, steel sheet piles and secant piled walls.
- Joints between floor slabs and pile caps.
- Remedial 'breaking out' of concrete.
Description
Adcor 500S is a thick sectioned, conformable, hydro-expansive waterstop for preventing water entry through joints in concrete sub-structures. The conformable, swellable polymer butyl rubber waterstop strip expands in contact with water and 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® has been specifically developed to provide higher performance than conventional bentonite or swellable rubber waterstops.
Features and benefits:
- Controlled volumetric expansion reduces the 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 minimum 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 or thaw cycling.
System components:
Can be used in conjunction with:
- Adcor® Mastic: A hydrophilic mastic for use as a bedding bead on irregular concrete surfaces prior to the application of Adcor 500S.
- Adcor® Adhesive MS: An adhesive for gluing Adcor 500S to smooth concrete, steel, and plastic substrates.
- Pak Adhesive™: A contact adhesive for gluing Adcor 500S to smooth concrete, steel, and plastic substrates.
