Leakmaster

Leakmaster is a one-component swelling waterstop sealant that, like Hydrotite, expands on contact with water. Prior to expansion, Leakmaster is suitable for bonding to a wide variety of substrates including concrete, rock and metals. Once applied, Leakmaster acts as high performance water proofing seal for precast applications such as storage reservoirs and utility vaults.

Leakmaster Applications:

  • Rough or uneven surfaces
  • Waterstop for pipe penetrations
  • Form ties
  • Construction joints in precast and cured-in-place concrete

Features of Leakmaster:

  • Easy to handle and apply.
  • Highly versatile
  • Expands up to 2 times in volume following contact with water
  • Gun-grade sealant that is moisture-cured to form a tough, hydrophilic rubber elastomer
  • Protects against joint movement or concrete shrinkage
  • Very economical means of waterproofing

Suitable for use on a wide range of substrates, with excellent adhesion
