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:DTM.E polyester composite waterproofing membrane, cheaper than the asphalt membrane?
the product in line with GB18173-2006 "polymer waterproof material" national standards.
Q:BS waterproofing membrane is modified? There are not a few thick drawings, how to do
Do not indicate the thickness can contact the design unit, you can also judge according to the waterproof level
Q:Asphalt waterproofing membrane and polymer waterproofing membrane
Polymer modified asphalt waterproofing membrane according to the polymer modifier material is divided into: elastomer modified asphalt waterproofing membrane and plastic modified asphalt waterproofing membrane.
Q:What are the requirements for frost resistance of basement floor polymer waterproofing membranes?
Sbs elastomer modified asphalt membrane is -25 degrees,
Q:Why the roof of the waterproof membrane and insulation rock wool board to do between the isolation layer?
2, the insulation layer can be done on the waterproof above, according to the nature of insulation materials, insulation layer and waterproof layer can be set between the isolation layer or not set. If the waterproof layer on the laying of polystyrene foam board, do not need to do isolation layer; if the block of inorganic insulation materials, such as foam glass, waterproof layer should be set on the cement mortar protective layer; if the waterproof membrane to do Foam concrete or polyurethane block insulation, you can dry in the coil a linoleum for the protection of the isolation layer.
Q:Construction Measures for Waterproof Coil in Winter
3. Do the seam and the end of the handle. In order to improve the reliability of the winter construction, to prevent the waterproof layer after the hot-melt paving seam with the possibility of seaming, requiring the mouth and the end of the mouth are sealed with sealing material to improve the waterproof impermeability.
Q:How is the water level rated and how many grades are used?
1, roof waterproof level 1: Application: particularly important or waterproof with special requirements of the building; Waterproof layer of reasonable use of life: 25 years; Waterproof layer selection of materials: should use synthetic polymer waterproofing membrane, polymer modified asphalt waterproofing membrane, metal sheet, synthetic polymer waterproof coating, fine stone concrete and other materials; Fortification requirements: three or more than three waterproof fortification.
Q:SBs waterproof cold sticky how to do?
4, paving sheet waterproof layer. Cold sticky construction of the joints is a weak part of the joints, in order to ensure the quality of seams waterproofing, each piece of the film should be posted when the standard line, that is, paving the first piece of paper before the grass, playing a good standard line, Along the shop paving, continue to pave the way, in the already prepared on the roll of the required width of the overlap and then play a good line, as a continuation of the standard line of sheet. Paving when asked adhesive or asphalt glue brush evenly, do not reveal the end, not accumulation, and need to be part of the solvent before they can roll pressure exhaust. Lap seam after the seam overflow overflow adhesive, should be flattened seal. At low temperatures, it is advisable to use hot air heating measures.
Q:Polyurethane and SBS membrane waterproof
 Rubber and plastic waterproof materials The research and use of such waterproof materials began in the 1950s. The raw materials are mainly chloroprene rubber, butyl rubber, EPDM rubber, polyvinyl chloride, chlorosulfonated polyethylene, polyisobutylene and polyurethane, can be made of flexible tire waterproofing membrane, waterproof film, waterproof coating Membrane materials, as well as ointment, clay, sealing tape and other sealing materials. These products have high tensile strength, elasticity and elongation, adhesion, water resistance and good weather resistance and other characteristics, can be cold, long service life.
Q:What is called a waterproof roll dry shop, wet shop
The biggest difference between the two is the same bonding strength, wet pad bonding strength is much larger than the dry shop method.
