Product Description:

Elastomer (SBS) Modified Bituminous Waterproof Sheet Material is a thermoplastic and elastic 

modified bituminous dipping and coatingmaterial made out of Stylene-Butadiene-Stylene (SBS),the filler base is polyester felt, glass fiber felt and glass fiber reinforced polyester felt, it is a kind of rollable sheet water proof materials with the surface cover of the isolating materials like polyethylene film, fine sand and mineral slice (or particle) etc.

Type and Specification

Classified by filler base: Polyester filler (PY), glass fiber 

filler(G) and glass fiber reinforced polyester filler (PYG). 

·Classified by upper surface isolating material: Polyethylene 

film (PE), fine sand (S) and mineral particle (M).

·Classified by lower surface isolating material: Fine sand 

(S) (note: the mineral particle with the fine sand diameter not 

more than 0.6mm) and polyethylene film (PE).

·The physical and mechanical properties were divided in 

Type Ⅰ and Type Ⅱ.


—Filament polyester filler base sheet material:

·The combination of filament polyester filler base and SBS 

modified bitumen, forms a high performance and high class 

comprehensive water proof sheet material.

·Forming a high strength water proof layer, to have strong 

resistance agaist water pressure.

·Good performance of breaking resistance, tearing resistance, 

fatigue resistance, corrosion resistance, mould resistance and 

weather resistance;

·High tensile strength, high elongation, high adaptive capacity to 

base shrinkage,deformation and fracture.

·Good resistance performance of low and high temperature: It 

still works under -50 ℃ , adaptive to cold and hot surroundings, 

especially in chilly region.

·Good workability: Hot melt cementation, we are able to contruct 

in the four seasons of the whole year, hot-joint is able to be reliable 

and durable.

—Alkali-free glass fiber filler base sheet material:

·Combination of economical filler base and high performance 

SBS modified bitumen.

·Higher tensile strength, excellent resistance to high and low 


·Good performance of corrosion resistance, mould resistance, 

weather resistance and good workability.

—Glass fiber reinforced polyester filler base sheet material:

·We may use mechanical mounting method to construct, and it is 

safe and environmentally friendly.

·The product has better dimensional stabiliy.

·Water proof for various industrial and civil engineerings.

·Underground water proof and damp proof for industrial and civil 

engineering, and water proof for indoor swimming pool and fire pool 


Application Range

·Water proof for municipal engineering such as subway, tunnel, 

concrete road surface, bridge surface, sewage works and refuse 

landfill etc.

·Water proof for water conservancy facilities like canal and water 

pool etc .

Application range for various filler base and surface sheet 


·Polyester felt filler base elastic modified bituminous water proof 

sheet material is appropriate to the roof and underground water 

proof engineerings of industrial and civil engineering projects.

·Water proof type Ⅱ is appropriate to roof type Ⅰ and Ⅱ and 

underground water proof projects.

·Glass fiber reinforced polyester filler base sheet material is 

appropriate to mechanically-mounted single layer water proof, but 

must pass the wind load test.

·Glass fiber felt filler base sheet material is appropriate to the roof 

of structurally stable building and suitable for underground water 

proof project.

·Exposed surface is suitable to have water proof sheet material 

with non-transparent mineral particle as upper surface isolating 


·The water proof sheet material with find sand as surface 

isolationg material is appropriate to underground constructioin
