A thick sectioned, hydro-expansive waterstop for preventing water entry through joints in concrete sub-structures.

The swellable polymer/ butyl rubber waterstop strip expands in contact with water, and when fully encapsulated by poured concrete, will form a seal against concrete faces.

The seal resists hydrostatic pressure, stopping water from entering sub-structures. Developed to provide higher performance than conventional bentonite or swellable rubber waterstops.

Features and benefits:

  • Controlled, reproducible, volumetric expansion, which reduces the risk of concrete spalling.
  • Cohesive strength maintained after volumetric expansion.
  • Malleable and plastic, enabling easy application to a variety of concrete profiles.
  • Can be installed into a variety of irregular substrates.
  • No need for the use of protective steel mesh.
  • Allows for simple overlap jointing on site.
  • Reproducible swell after wet/ dry cycling.
  • Can be easily joined to other polyvinyl chloride (PVC) waterstops at movement joints.
  • Unaffected by freeze/ thaw cycling.

Applications:

  • 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.
  • Pipe penetrations through floors and walls.
  • Remedial ‘breaking out’ of concrete.

Can be used in conjunction with Triton SwellMastic - consult manufacturer for details.
