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:Is the waterproofing membrane an insulating material?
3, with a metal carcass resistant root puncture waterproofing membrane, such a coil in the metal copper fetal base, there are other metal fetal base of the coil.
Q:How to distinguish whether the waterproofing membrane is polyester tires?
The easiest way is: hand tear, because the polyester tire than the composite tire body more flexible, so the direct way is to tear the hand is "composite tire", on the contrary is the "polyester tire"
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:Polyethylene polypropylene waterproofing membrane forming. Secondary molding, what does it mean? How to distinguish?
Polyethylene polypropylene waterproofing membrane from the middle of the "polyethylene" chip, two-sided composite "polypropylene non-woven" made, one method is in the extrusion production of polyethylene film at the same time, when the polyethylene is still in a soft state , In the upper and lower sides of the membrane composite polypropylene non-woven, the temperature can not be too high and polypropylene buried too much, the temperature can not be too low, otherwise the sticky on the sticky.
Q:Is the asphalt waterproofing membrane facing the side?
2, pre-shop anti-stick method: This kind of membrane to synthetic polymer self-adhesive coil mainly single-sided self-adhesive or double-sided self-adhesive. In the construction of the floor, the coiled surface of the coil facing the day, the membrane surface does not do protective layer, in the above bar reinforced concrete pouring. In the construction of the wallboard, for the foundation pit and the structure of the wall spacing is too small, the envelope as a concrete structure of the outer wall of the wall panels, wall panels only support the internal mold, waterproof membrane nails nailed to the envelope , The adhesive surface facing the basement structure, the concrete directly with the waterproofing membrane bonding surface combination.
Q:What is rigid waterproof, flexible waterproof?
4, rigid waterproof and rigid waterproof material is not the same concept, the same flexible waterproof and flexible waterproof material is not the same concept. Such as polyethylene polypropylene is a flexible waterproofing membrane, with polymer mortar (or bonded paste) bonded polyethylene polypropylene composite waterproof layer, it is rigid waterproof, because the mortar binder in the grassroots deformation will crack , The web between the web and the web can not withstand the deformation of the grassroots, and the water infiltrates from the lap to cause damage to the waterproofing layer.
Q:Do you know how many square meters of waterproofing membrane to send a set of tests?
PVC waterproofing membrane: take a roll at the end of 0.3m at the end of the interception of 3m full-width coil sample 2, 2000 square meters for a group, the lack of a group also. Polymer waterproofing membrane: 5000 ㎡ sheet for a group.
Q:The difference between high polymer modified asphalt waterproofing membrane and sbs
SBS modified asphalt waterproofing membrane is a kind of polymer modified asphalt waterproofing membrane, which is included with the included relationship.
Q:What is the difference between PET waterproofing membrane and BAC waterproofing membrane? What is the commonality? Is BAC a PET?
BAC is not equal to PET, carcass material is not the same, and BAC also fiberglass tire coil.
Q:3MM thick, one square meter waterproof membrane SBS price?
1,3MM thick, one square meter of waterproof membrane SBS prices in 20 --- 30 yuan range.
