Product Description:

Brief Introduction:


This waterproof membrane is made from ternary ethylene-propylene rubber. Weadopts the world advanced equipment of cold feeding extrusion and continuous valcanization technology.

 With the best performance among  high polymer waterproof materials, EPDM is of exceptional elasticity and will not split or crack under normal building movement.

1)Good flexibility, creep properties and malleability, and the superior adapting ability to the deformation of the primary stress generated.

2). Tight adhesion between waterproof layer and basic layer, no channeling water. Having self healing ability after piercing.

3).Operation without heating. And possessing the reliability of pasting by itself with super strong connection of sheet materialand adhesion of same base.

4). Convenient and safe operation, no pollution to the environment.



1)  Make sure the roof deck smooth,clean and dry(Moisture<9%),then apply the surface of roof deck homogeneously with a kind bitumen paint till dry to start application.

2)  There are two methods in application:

One way is by heating and melting method---Heat the polyethylene film of the membrane and roof deck surface by heating and melting method to be nearly melted(not flowing),then install the membrane fully bonded to the roof deck with overlaps of 5-10cm.

The other way is by cold adhesive method---Pour the cold adhesive homogeneously on the roof deck then roll the membrane to install it to be fully sticked to roof deck.

By heating and melting method and by cold adhesive can be used in alternation in application as requested.

3)  After application,a full serious inspection is required to make sure no air bubble,no fold,no falling away etc to guarantee the waterproof life

Q:What is the difference between polymer waterproofing membrane and cross film waterproofing membrane?
he strong cross-over film of the product is a high-strength HDPE film formed by the cross-laminating process. The film and the like have the same vertical and transverse elongation ratio. The coil does not send deformation, more beautiful and waterproof reliable.
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:What are the advantages and disadvantages of waterproofing membrane?
The waterproof membrane study its drawbacks: waterproofing is performed when the amount of coating material according to the cross-sectional shape of the waterproof base waterproof construction, the need for a complex shape of the base layer a plurality of splicing, waterproofing overlap each other at the bonding difficult than Large, due to the impact of multi-block splicing waterproof layer of beauty; then completely absolute seal will become the main problem, the biggest hidden dangers, the most opportunities is the coiled parts of the coil; then high-grade waterproofing membrane with a few decades durable for a long time, but the country is still less matched the binder, and the binder material itself due to environmental factors such as loss of adhesion is often ahead of function, thus leading to the failure of the waterproof self-evident; Furthermore Waterproof membrane after the construction of the protection and leakage after the maintenance is also a problem, exposed waterproof layer of foreign mechanical damage prevention is very important, waterproof membrane and the grass-roots bonding, whether full of shops, shop, shop air, between the base layer and the web would be to go aqueous layer, regardless of any part of the cross-cutting breakage, degumming, drooling (even the only one), the entire coherent thereto waterproof power level Will lose all bad, if you can not find damaged and defective parts, the local repair is not possible, then only redo waterproof layer.
Q:Sbs modified asphalt waterproof membrane polyester type Ⅰ type Ⅱ how to distinguish
These two kinds of materials from the current surface is exactly the same, if it is experienced people, you can through the tension on the sheet asphalt to determine the initial situation, if the domestic refrigerator can reach -25 ℃ low temperature, can also be low temperature flexibility Not broken after the initial judgment). To correctly determine the need for sample inspection.
Q:Why the roof of the waterproof membrane and insulation rock wool board to do between the isolation layer?
Roof on the waterproof membrane and the insulation between the rock wool board to do isolation reasons: 1, leveling layer is generally in order to make waterproof sheet paving when the formation is not empty drums, and sometimes leveling layer can also increase the bond strength of the substrate and the grassroots. But not all of the membrane paving must be done leveling layer, such as polyethylene polypropylene waterproofing membrane is a special mortar as a binder, not very uneven in the base can be directly on the construction. The insulation layer of the grassroots level is generally not leveling layer, but do nothing bad, to reduce the block insulation material porosity, improve the insulation effect and the overall strength of the insulation layer is useful.
Q:APP selection of asphalt waterproofing membrane selection points
2, Ⅱ type polyester tire modified PET asphalt waterproofing membrane, with a large pull, high elongation, heat resistance and good low temperature flexibility and so on. Applicable to the general and relatively cold or more hot areas, waterproof level for the I, Ⅱ, Ⅲ level roof waterproofing works.
Q:About asphalt waterproofing membrane
5, oil asphalt felt is the asphalt membrane, asphalt membrane is not modified by the coil, usually specifically felt. 6, if it is asphalt-based waterproofing membrane, including non-modified asphalt linoleum, polymer modified SBS coil, oxidized asphalt modified membrane.
Q:PVC waterproof membrane effect how
3, self-adhesive method: with self-adhesive waterproofing membrane, without heat construction, do not need to glue the material, and the construction of the bonding method.
Q:Polyurethane and SBS membrane waterproof
Paste asphalt linoleum. The cold binder material prepared by diluting the bitumen with solvent is developing. Various solvent and water emulsion asphalt or asphalt rubber coatings for roof waterproofing, should be strictly selected anti-cracking, tensile, anti-aging performance and good weatherability thick coating varieties. In addition, all kinds of ointment for dealing with the general building of the joints waterproof.
Q:Waterproof membrane in the escape when the full shop, empty shop, shop, shop what is the difference?
2, the shop laying the membrane, the membrane and the grass-based use of sticky. Requiring each web and the base of the bonding surface of not less than two, each paste width of not less than 150mm. The paste is located under the web and coil.
