Product instruction

EPDM waterproof membrane is made from ternary ethylene-propylene rubber. With the best performance among high polymer waterproof materials, EPDM is of exceptional elasticity and will not split or crack under normal building movement.



Detailed Product Description 

1. High adhesive strength, durability, long after the bond; 
2.Excellent weathering resistance, aging resistance; 
3. Nano stabilizer added ingredients, low heat dimensional change; 
4. High tensile strength, elongation, strong grass-roots stretching or cracking adaptability, resistance to low temperatures, can be adapted to -40 ℃; 
5.Cold installation, easy to operate, reduce environmental pollution and improve working conditions of workers;




EPDM (TBD) selfadhesive waterproofing membrane used in roofing projects, exposed roofing, building foundations, basements, storage tanks, subways, tunnels, supermarkets, airports and other buildings waterproof.

Q:Waterproof building materials after the construction of drums, bubble is what reason?
Reason 2: Construction, due to the construction of the membrane waterproof layer of paving is not true, so that part of the empty, remain in which to form a bubble. Control measures: in the asphalt waterproofing membrane construction, the first surface of the coil clean. When laying the web, the mastic should be painted evenly and carefully compaction work to enhance the cohesive force between the web and the base, the web and the web. High polymer modified asphalt waterproofing membrane construction, the flame heating to be uniform, full, moderate. Paving to roll forward while hot, while rolling with a pressure roller to exclude the air below the coil.
Q:How to distinguish whether the waterproofing membrane is polyester tires?
Polyester tires (polyester fabric, polyester felt, polyester linoleum fabric) with high strength, high extension and puncture resistance, light weight, high tensile strength, good permeability, high temperature, anti-freeze, anti-aging, corrosion. Technical requirements, including the appearance of quality, intrinsic quality assessment projects and internal quality reference project, the indicators are in line with the provisions of the waterproof standards. Routine project tests should be in accordance with national standards test methods, thermal stability, bending, impregnation, water resistance test methods have done a detailed test.
Q:What is sbs, app modified asphalt waterproofing membrane
Their characteristics and differences: First, SBS modified asphalt waterproofing membrane (polyester tires): SBS modified asphalt waterproofing membrane is SBS rubber modified petroleum asphalt cited as the invasion coating, polyester fiber non-woven , Jute cloth, glass fiber mats were made for the fetal base, the plastic film for the anti-sticking isolation layer, the selection, ingredients, eutectic, invasion, composite molding, curling and other processes processing production. Such as building dragon TJ-242 SBS elastomer modified asphalt waterproofing membrane. Features: The use of polyester felt (filament polyester non-woven) mechanical properties, water resistance, corrosion resistance is also very good; elastic and low temperature performance has improved significantly, the effective range of (-25 ~ 100) ℃; Excellent fatigue resistance. Use: for high-level and high-rise buildings of the roof of the single-layer laying and composite use, can also be used for basement and other waterproof and moisture, more suitable for the northern cold areas and structural flexibility of the building waterproof.
Q:Basement SBS Waterproof Coil Division I and II type What is the difference? How is the site identified?
Type I low temperature flexibility is -20 degrees, pulling force of 500N / 5cm, elongation of 30%. Type II low temperature is -25 degrees, tension of 800N / 5cm, elongation of 40%. The appearance of the general can not distinguish, you can take the sample to the laboratory to be a tensile test on it.
Q:Whether the polyester waterproofing membrane can be used for roofing waterproofing
2, roof waterproofing is not just a layer of waterproof membrane, according to the design of the coating is usually used waterproof layer + polyester membrane waterproof layer;
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:How is the water level rated and how many grades are used?
2, the roof waterproof level 2: Applications: important buildings and high-rise buildings; Waterproof layer of reasonable use of life: 15 years; Waterproof layer selection of materials: should choose high polymer modified asphalt waterproofing membrane, synthetic polymer waterproofing membrane, metal sheet, synthetic polymer waterproof coating, high polymer modified asphalt waterproof coating, fine stone concrete, flat tile, linoleum Tile and other materials; Fortification requirements: two waterproof fortification.
Q:Is the foundation pit waterproofing and the foundation pouring on the working face?
2, your construction process is not clear: I tell you listen to the basic cushion after the completion of the construction, the cushion surface dryness to reach more than 90% can be done when the membrane waterproof layer, waterproofing membrane construction is completed, then do C20 40 ~ 50mm fine stone concrete protective layer, the construction is completed, generally the next day can be tied in the above bar.
Q:What is the use of waterproof membrane?
It is the first barrier between the foundation of the project and the building, which is the first barrier to the entire project. It plays a vital role in the whole project.
Q:What is the resistance type SBS waterproofing membrane?
The third is the combination of the above two principles. SBS resistant root puncture membrane has three kinds: 1, composite copper fetal base SBS modified asphalt waterproofing membrane. Mainly using copper tires to puncture strength, while copper ion drive plant roots. 2, copper foil tire SBS modified asphalt waterproofing membrane. Mainly the use of copper ion drive plant roots, while a certain anti-piercing strength. 3, SBS modified asphalt root resistant puncture waterproofing membrane. Mainly chemical resistance to root.
