Description:

DE NEEF SWELLSEAL WA is a single component gungrade hydrophilic waterstop, designed for sealing smooth to very irregular construction joints and pipe penetrations.

DE NEEF SWELLSEAL WA is supplied in cartridges or sausages. Material cures and swells in the presence of moisture or water. Curing time is dependent on temperature and humidity, i.e. curing time will decrease if temperature and relative humidity are higher. DE NEEF SWELLSEAL WA will become firm in 24-36 hours.

Uses:

• Sealing rough and smooth construction joints of cast in-place or precast concrete in wet and underwater applications.
• Sealing joints in pre-cast segments in wet or underwater applications (e.g. manholes, box culverts, cable ducts and pipes)
• Sealing joints between sheet piles.
• Creating good contact between Hydrophilic Waterstop Strips and rough concrete surfaces.

Advantages:

• Solvent free
• Can be applied to wet surfaces or underwater when concrete is poured within 6 hours
• Adheres to concrete, PVC, HDPE, steel, & fiberglass
• Expands to more than 200% of original cured volume
• Flexible system, adapts to irregular surfaces
• Easy application with standard caulking guns
• Good chemical resistance
