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.
