Description:

Adcor® SAS 500S is a swellable hydrophilic waterstop that provides a continuous bond to substrates, preventing water entry through joints in concrete sub-structures. It allows quick installation in any construction assembly, making it the smart choice over nail and mesh fixing.

Adcor® SAS 500S combines GCP’s proven self adhesive SIS technology with the Adcor® conformable, swellable polymer/butyl rubber waterstop strip that expands when in contact with water.

Adcor® SAS 500S bonds on concrete, metal, or PVC substrates. It is designed for the engineer who wants a continuously well sealed joint, and the applicator who wants a fast and easy way to apply a swellable hydrophilic waterstop between the steel reinforcing bars, in vertical, horizontal & overhead surfaces. You simply peel the release paper and press the strip onto a clean surface to install it.

The sealing of the joint is achieved by the expansion of Adcor®. 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® SAS 500S has been specifically developed to provide a faster waterstop application and higher performance than conventional bentonite or other swellable rubber waterstops.

Advantages:

• Faster, safer installation without fixings or tools.
• Strong instant adhesion to substrates in any position (horizontal, vertical or overhead).
• Easy application between steel bars.
• All in one – fixing and swelling waterstop.
• Conformable – can be installed onto a variety of irregular geometrical substrates.
• Controlled volumetric expansion – reduces risk of concrete spalling and premature swelling.
• Volumetric expansion min 100% in cement water
• Retains cohesive strength at both original and expanded volume.
• Resists at least 87 psi (6 bar) hydrostatic pressure.
• Reproducible swell after wet – dry cycling.
• Unaffected by freeze/thaw cycling.
• Simple overlap jointing on site.

Applications:

• 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.
• Vertical, overhead, soffit, horizontal locations.
