Product Overview

Product Files


This Leakmaster crack sealant is a one component polyurethane water-swelling sealant with excellent and unique physical properties. Its development was based on technology and experience in water-swelling waterstops. 

It can be applied to joints, etc., in swimming pools, civil engineering, construction and water services for seals where conventional solid waterstops cannot be applied easily. This includes irregular shaped joints, rough surfaces, odd penetrations, etc. 

It has a finished color of gray.


  • Water sealing joints of cast concrete.
  • Sealing rough surfaces.
  • Good adherence: Before swelling it adheres to various materials such as concrete, metal, glass, etc.
  • Can support 20 m heads of water.
  • Excellent for pipe penetration.
  • Easy application to smooth and uneven surfaces as a moisture-cure one component type water-swelling sealant.
  • Physical properties: after hardening, it has better physical properties than those of conventional putty type sealants.
  • Water swelling up to approx. 2 times in volume as a result of its water absorption and swelling mechanisms. Provides excellent water sealing properties (for construction joints) without losing its rubberlike elasticity.
