Application

For passive protection of movement joints and construction joints in reinforced concrete structures. Used for non-suspended slabs in water retaining structures such as reservoirs, swimming pools and sewage treatment tanks.

Description

A passive external PVC waterstop system manufactured in a range of sizes for protecting joints in concrete basements and sub-structures.


Features and benefits:

  • Proven design - the original external waterstop used extensively in water excluding and water retaining structures.
  • Flexible - will accommodate movement during construction and service life.
  • External seal - protects reinforcement from water ingress.
  • Pliable - remains flexible at low temperatures.
  • Four ribs - provide extended and tortuous water path.
  • Stabilising/Nailing flange - allows fastening without damaging waterstop and prevents displacement or folding of ribs during concreting.
  • Pre formed junction pieces - factory made range of standard junction pieces.
