· SBS modified bitumen waterproof membrane both have strong tensile strength, large elongation, freezing resistance, resistance of salt and other chemical mediators and resistance of aging and they are adaptive to flexibility, deformation and fracture of the base.
·Form a coriaceous watertight layer, reliable waterproof performance;
·The combination of unique formula and high quality filament polyester, makes the large thickness and excellent performance, and is able to have resistance for paving and grinding of the hot aggregates.
·It has stretching obedience for bituminous concrete cracks.
·It has durable adhesive performance and excellent anti-shearing performance at high temperature, and is able to transmit and bear the traffic loads effectively.
·The complete system-supporting materials and application technology ensures the engineering quality.

·It applies to various industrial and civil building roof waterproof constructions; SBS Type Ⅰ modified bituminous waterproof sheet material in standard of JC/T 974-2005 is mainly used in waterproof of bituminous
concrete pavement by paving method;
·It applies to industrial and civil building underground waterproof and damp proof constructions, indoor swimming pools, fire pools and so forth;
·SBS modified Ⅰ Type are also used in waterproofing engineering constructions of concrete bridge surface, airport runway and parking lot etc.
