Premium grade, water swellable, waterstop range.

Hydrotite is a hydrophilic waterstop which exibits excellent durability and water sealing capacity. It expands as it absorbs water and fills concrete joint gaps conforming to the gap variation, ensuring excellent sealing. Hydrotite is based on the technology of hydrophilics, a material which expands in a controlled fashion by approximately eight times by volume in the presence of moisture to create a pressure seal within the joint.

When properly installed, Hydrotite is capable of sealing heads of water up to 50m and is used throughout the construction industry to seal horizontal and vertical construction joints for poured in-situ concrete.


Hydrotite is used where watertight integrity is the prime issue. Typical applications include construction joints for in-situ concrete

  • Sewerage & water treatment plants
  • Pipe penetrations
  • Subway stations
  • Swimming pools
  • Basements
  • Reservoirs
  • Tunnels
  • Pits


  • Self-adhesive makes installation easier and reduces construction costs
  • Co-extruded design means expansion is directed across the joint for maximum seal
  • Delay coating to help prevent premature expansion
  • Unaffected by repeated wet and dry cycles
  • No site welding is required for traditional PVC waterstops
  • No need for special intersections; joining is by simple butt joins
  • Can be applied to rough surfaces using Leakmaster gun-grade waterstop
  • Can be joined to traditional PVC waterstop
  • No compaction or displacement problems
  • Complies to AS/NZS 4020:2018
