Leakmaster

Gun applied, water-swellable, waterstop paste.

Leakmaster 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, such as Hydrotite.

After hardening, it has excellent physical properties together with rubber-like elasticity and excellent water-sealing properties.

Uses

Leakmaster is applied to non-moving/low-movement joints in civil engineering, construction, and water services for seals where conventional solid waterstops cannot be easily applied.

• For bonding Hydrotite profiles to rough concrete surfaces
• Water sealing joints of cast in-situ concrete
• Water sealing around “H” section steel joists
• Sealing against rough surfaces
• Water sealing in shotcrete
• Sealing joints in pre-cast box culverts
• Excellent for pipe penetration
• To provide sealing around traditional heat-welded PVC and Hydrotite waterstop joins to provide ‘belts and braces’ seal before a concrete pour

Advantages

• Easy application to smooth and uneven surfaces as a moisture-cure one component type water-swelling
  sealant
• Can support 20m heads of water
• 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
• Good adherence: Before swelling, it adheres to various materials such as concrete, metal, glass, etc.
