—Long fiber polyester base membrane:

·The combination of long fiber polyester base and SBS modified bitumen forms an excellent comprehensive performance and high-quality waterproof membrane;

·High strength waterproof layer and strong water pressure resistance;

·Good performance of breaking resistance, tearing resistance, fatigue resistance, corrosion resistance, mould resistance and weather resistance;

·High tensile strength, high elongation, good adaptability to shrinkage deformation and cracking of the substratum;

·Good temperature resistance: can work under -20 ℃ , suitable for cold and hot regions, especially for cold area;

·Good workability: can be applied by torch-applied method in any season and hot-joint makes the work reliable and durable.

—Alkali-free glass fiber filler base membrane:

·Combination of economical filler base and high performance SBS modified bitumen.

·Higher tensile strength, excellent resistance to high and low temperature.

·Good performance of corrosion resistance, mould resistance, weather resistance and good workability.

—Glass fiber reinforced polyester filler base membrane:

·It is safe and eco-friendly by using mechanical mounting of construction.

·The product has better dimensional stabiliy.

·Waterproofing for various industrial and civil construction engineering construction projects;

·Waterproofing and dampproofing for underground constructions of industrial and civil construction engineering;and waterproofing for indoor swimming pool and fire pool etc;

·Waterproofing for municipal engineering such as subway, tunnel, concrete road surface, bridge surface, sewage works and refuse landfill etc;

·Waterproofing for water conservancy facilities like canal and water pool etc .

Application range for various filler base and surface membrane：

·Polyester felt filler base elastic modified bitumen waterproof membrane is appropriate for the roof and underground waterproof constructions of industrial and civil engineering projects;

·Glass fiber reinforced polyester filler base membrane is appropriate for mechanical mounting single layer waterproofing, but must pass the wind load test;

·Glass fiber felt filler base membrane is appropriate for the roof of structural stable buildings and underground waterproof projects;

·Exposed surface is suitable to have waterproof membrane with non-transparent mineral particle as upper surface isolation material;

·The waterproof membrane with fine sand as surface isolation material is appropriate for underground construction projects.
