the self-adhesive waterproofing membrane with high-performance and cold construction is a kind of high-performance cold construction self-adhesive waterproofing membrane composed of special cross laminated high-density polyethylene (hdpe) strong film and high-quality polymer self-adhesive rubber asphalt by special process. it has excellent dimensional stability, thermal stability, uv resistance and bidirectional tear resistance. the strong cross film used in the product is high strength hdpe film formed by cross lamination process. the longitudinal and horizontal elongation of the film made by this process is mold like, and the coiled material will not deform, which is more beautiful and has more reliable waterproof effect.
high quality pressure-sensitive reaction self-adhesive layer can combine with concrete base rapidly, and its excellent self-adaptive performance and local self-locking water performance greatly reduce the leakage probability. the polymer (chain segment) and cement hydrate (silicate network) form interpenetrating network structure in the coil rubber, and finally form continuous mechanical bond, which is permanently sealed on the cement binding material components.
with the new wet bonding technology, the membrane and the structural concrete form a permanent organic combination, without water leakage hidden danger, and completely improve the reliability of the waterproof layer.
it has excellent performance of impact resistance and puncture resistance, can bear the impact of construction load and reinforcement, and can be directly poured concrete without extra protection during pre laying and anti sticking construction.
the self-adhesive layer with special formula has strong self-healing ability and unique self-healing ability for slight construction damage.
chemical resistance, good resistance to alkali water from concrete. it is resistant to microorganism, mould and corrosion.
in wet paving construction, the requirements for the construction surface are low, and it is not affected by the moisture of the base course. it has obvious advantages in the construction in rainy season and in the rush period.
