Remark: The property of artificial weathering might not be applicable to non-exposed product

Product Features:

a) High Strength

b) Hot-air welded seams for long-term performance

c) Proven membrane performance

d) Excellent resistance to plasticizer extraction and migration performance.

Physical Property

1. Exposed to sunshine: UV rays resistance, long service life and aging resistance

2. Easy installation and dimensional stability: can be wieldable under wide range of temperature and experience minus dimensional change in thermal treatment

3. High tensile strength and elongation thus can accommodate movements of substrates
4.Good flexibility under low temperature, good adaptability to ambient temperature difference
5, Secure anti-puncture and good rooting resistance, no pollution caused to environment when being welded and good    waterproofing choice for plant roofs 
6. Good plasticity: convenient and fast treatment of detailed parts of corners and edges


 Product usage

a) Roofing (covered & exposed roofs)/ Re- roofing

b) Tunnel Lining

c) Tanking of Underground structures

d) Lining of evaporation ponds & artificial lakes

e) Lining of drinking water tanks & swimming pools

f) Agricultural purposes & Lining of irrigation canals

Q:Asphalt composite tire flexible membrane is SBS
This is two kinds of materials, in addition to the same appearance, the same hot-melt construction, its physical and mechanical properties, anti-aging properties are very different.
Q:How to distinguish the degree of sbs waterproofing membrane?
Method 1: Look at the product packaging instructions or factory inspection report, if it is type Ⅰ coil, low temperature flexibility is -20 °, if it is type Ⅱ coil, low temperature flexibility is -25 °.
Q:Coil waterproof roofing requirements
4, the female wall to leave a waterproof membrane head groove, the height of the project after the completion of the requirements of more than 300 flood height, the general height of 400-500 is appropriate.
Q:What is the meaning of "channel" and "layer" in the practice of polymer waterproofing membrane?
Corresponding material thickness in line with the requirements of a layer of waterproof water called a waterproof.
Q:What should the attention of the membrane waterproof construction?
(3) Paving method: peel the coiled surface of the release paper, the membrane attached to the base surface, the long side of the membrane waterproof material to keep 50mm, short side lap to keep 70mm, the coil required to maintain a natural relaxation , Do not pull too tight, the web should be done, should immediately use a flat vibrator full compaction, the vertical parts of the rubber hammer with real;
Q:Why the roof of the waterproof membrane and insulation rock wool board to do between the isolation layer?
3, in the insulation layer on whether to protect the isolation layer according to the construction of the insulation layer on the destruction of the role of the waterproof layer. Since the waterproofing membrane has been completed construction, indicating that the flatness has reached a higher demand, and the insulation layer of the grass-roots flatness requirements do not exceed the requirements of the web paving, so waterproof surface without leveling layer, but may need to do protection Isolation layer.
Q:Construction Measures for Waterproof Coil in Winter
High polymer modified asphalt waterproofing membrane to hot melt construction is more simple, the construction temperature can be within -10 ℃. 1. Base treatment agent to be volatile completely, full. Winter construction often use solvent-based treatment agent, one is free from frozen, the second is easy to operate. Low temperature in winter, solvent evaporation slow, so should strictly control the solvent drying time, winter in 10h above the basic volatile full, finished, and then arrange the hot melt coil process to prevent the fire.
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:Why is the top cover of the basement waterproofing? While the floor has to empty shop?
Waterproof membrane is mainly used for building walls, roofs, as well as tunnels, highways, landfills, etc., to resist the external rain, groundwater leakage can be curled into a roll of flexible building materials, as the basis for engineering And no leakage between the building connection, the entire project is the first waterproof barrier, the entire project plays a vital role. The main products are asphalt waterproofing membrane and polymer waterproofing membrane.
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.
