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
