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® is a unique product that has been specifically developed to provide higher performance than conventional bentonite or swellable rubber waterstops.

Application:

 

  • 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.

Features/ Benefits:

 

  • 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.

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.
