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

Q:What is the difference between pressure-sensitive self-adhesive waterproofing membrane and sbs asphalt waterproofing membrane?
1, from the product level (1) pressure-sensitive self-adhesive waterproof membrane is a new type of product, is the fourth generation of products, and Sbs asphalt waterproofing membrane is the second generation of products, so that the former is a new product, then the effect is certainly better than
Q:How to distinguish the degree of sbs waterproofing membrane?
How much of the weight of the waterproofing membrane is the "low temperature flexibility" of the web is the bending performance of the web in a negative temperature condition, and it is said that it is bent in a very cold environment without cracking. Generally speaking, the low temperature of the synthetic polymer membrane is better, and the low temperature performance of the modified asphalt membrane is related to the modification technology.
Q:What is the material on the insulation layer on the waterproofing membrane?
3, the isolation layer before the use of paper gray or low-grade mortar, due to the construction of rigid layer, the pile of ash is easy to enter the concrete, so no. Low-grade mortar construction of the transport car on the waterproof layer of damage, and anti-slip performance is not ideal, so less used. Now generally use dry cloth linoleum together, but also useful thick plastic film and other materials.
Q:Whether the polyester waterproofing membrane can be used for roofing waterproofing
4, polypropylene waterproofing membrane in the actual use of the results reflected is not ideal.
Q:What is rigid waterproof, flexible waterproof?
1, rigid waterproof means that: waterproof layer by the tensile force is greater than the tensile strength of waterproof materials (including settlement deformation, temperature deformation, etc.), waterproof layer of brittle cracking caused by leakage of water, known as rigid waterproof. (Especially the "water leakage" waterproof layer), waterproof concrete mortar waterproof layer, thin layer of inorganic rigid waterproof layer (such as "water leakage" waterproof layer), and so on.
Q:BS waterproofing membrane is modified? There are not a few thick drawings, how to do
For example, class Ⅱ waterproof basement waterproof, if only a SBS waterproofing membrane, then its thickness requires 4 mm; if there are other waterproof layer, you can use 3mm.
Q:The shortcomings of polypropylene waterproofing, and the shortcomings of modified asphalt waterproofing membrane
The advantages of the membrane waterproof, such as: the construction is convenient, the construction period is short, not need to be cured after forming, is not affected by the temperature, the environmental pollution is small, the layer thickness is easy to hold and hold the fortification meter, the material is calculated accurately, the site management is convenient, Cut corners, even thick layer, empty shop can effectively overcome the grass-roots stress (effective in the grass-roots cracks to maintain the overall waterproof layer).
Q:What is the meaning of the node and the additional layer in the construction of the membrane waterproofing layer?
The role of the additional layer is to strengthen the protection to achieve double protection to reduce the probability of leakage.
Q:Why is the top cover of the basement waterproofing? While the floor has to empty shop?
Waterproof construction methods are generally reflected in the construction drawings. If not, please consult the designer. A waterproof, full of sticky. Secondary, sticky or sticky. Construction waterproof with waterproof material. According to each of the different basement waterproofing, the construction team will have its own waterproof concept and specific construction requirements.
Q:What is the PEDM waterproofing membrane material?
EPDM waterproofing membrane (EPDM) is the main material with ethylene propylene rubber, adding anti-aging agent, accelerator, and adding nano-materials, so that the waterproof membrane weather resistance, heat resistance, low temperature resistance has greatly improved
