EPDM waterproofing membranes

Products Description

 

EPDM waterproofing membrane is the modified materials. They are based upon EPDM rubber with modifier, softener and accelerant assistants’ added modifier, to provide flexibility and stability. Through the precise ingredients, mixing, extrusion, rolling, curing processes to make of modified EPDM Waterproofing material with high strength and high flexibility.

Characteristics

1, The excellent anti-aging, in the long term light, humidity, cold use of the natural environment, small changes in physical properties, used in the temperature: From -50 degree Celsius to +80degree Celsious.

 

2, With outstanding ozone resistance, resistance to ultraviolet and atmospheric corrosion of many chemical corrosive substances.

 

3, High tensile strength, high elongation, high flexibility, capable of sustaining a puncture of hard material, good anti-crack, high adaptability of the grass roots' contraction and the crack and deformation, and give full play to extend the performance, playing the role of waterproofing.

 

4, long lifetime, high durability can achieve more than 25 years.

 

5, The cold construction operation, no environment pollution and simple operation

 

 

 

Application Range

 

EPDM waterproof membranes form an effective barrier to liquid water or water vapor in the roof construction for industrial and civil engineering, underground engineering such as subway & tunnel, water conservancy tunnel, such as water pools & ditch, shelter, grain depot, land filling, subways.

 

 

 

APPLICATION METHOD

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.
