Application Range

(1)(PE)Self-adhering polymer modified bituminous waterproof sheets is widely used for
* non exposed level, underground and indoor engineering;
*cut-and-cover metro,tunnel,pool,canal and etc.
*Especially in the waterproof engineering can not use open flame.
(2)The upper surface which is coated by aluminum foil film and fine sand is widely used for exposed waterproof engineering.
(3)Double-sided self-adhered sheet is widely used for pre-laid and assistant waterproof,
It can also compound with variety of materials to form multiple waterproof system.
