SZ Self-Adhesive Polymer Modified Asphalt Waterproofing Membrane

SZ self-adhesive polymer modified bitumen waterproofing membrane is manufactured with a unique formula and 

process. The main waterproof layer is a chemically co-mixed self-adhesive elastomer modified with multiple polymer 

materials, with a composite silicon-based release film on the surface, making it a self-adhesive membrane. The active 

groups in the modified bitumen adhesive chemically bond with the cement slurry on the base surface, permanently 

integrating with the cement stone to form a "skin-like" waterproof layer, overcoming the defects of peeling and slippage 

common in ordinary self-adhesive membranes.

① Can be directly constructed on wet base surfaces, and also suitable for dry base surfaces (construction after 

sprinkling water to moisten);

② Bonded with cement slurry, easy to construct. When leveling the base, self-adhesive membrane can be paved 

while plastering cement mortar, saving labor and materials;

③ No open flame during construction, no need for organic solvent base treatment agent, environmentally friendly 

and energy-saving;

④ Has "water-locking" function: since the membrane is integrated with the base surface, it will not seep water even 

if damaged;

⑤ Can be constructed with pre-paved reverse adhesion method, and can be well bonded with post-cast concrete.
