Description
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.

Applications

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

Features

• 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
