Specification of FOSROC Supercast swelling WATERSTOP waterproofing
WATERSTOP Swelling is made of rubber which can expand 300% in volume when hit / submerged in water. Size 5 x 20 mm 15 m long.
Water-swelling sealant is a solvent-free one-component elastic sealant that expands in water. This is a urethane paste based on a pre-shaped polyurethane containing special grafting technology. The double seal seal mechanism with rubber elastic sealing and volume expansion and sealing after exposure to water is suitable for waterproofing concrete construction connections and preventing leakage of various embedded components. The sealant water swelling can be cured in a humid environment. The ripening time depends on the ambient temperature and humidity. The higher the temperature or humidity, the shorter the ripening time. After surface hardening (drying of Waterstop glue), the next concrete placement is ready.
Performance characteristics:
1. This is very good in working ability because it is a type of wet hardening single liquid.
2. When water swells, the effect of stopping water can be more reliably achieved.
3. Good adhesion to concrete, metal, glass, etc.
