Production features

1.With great tensile strength and elongation.

2. With good performance in temperature and weather resistance.

3. With superb performance in anti-puncture, impact resistance and root resistance.

4. Simply applied in construction.

5. No open fire or volatility of harmful solvent, safe, envrionment friendly, no pollution.

 6. Enough width reduces overlapping joint, which guarantees quality of the structure and reduces consumption of sheet.




According to the constituent, it can be divided into homogeneous sheet (code: H), fibre-backed sheet (code: L), sheet internally reinforced with fabric (code: P), sheet internally reinforced with fibre glass (code: G), sheet with fabic backing and reinforcement of glass fiber (code: GL).


Where to use

Construction method


Cold sticking adhesion

It's applied to side wall of basement, basement roofing. PVC sheet can be bonded tight by special adhesive with the base course, playing the role of insulation,protection and buffer.


Melt adhesion

1. The PVC waterproofing membrane should be paved smoothly without bending, drooping, strain, wrinkles, damage etc.
2. The solder side shall be cleaned and kept dry before seam welding. The angle between welding tip and welding direction should be 45o. Compression roller and welding tip parallel with a distance of about 5mm. Bright-colored melting appears around welding tip. Solder skips, skip welding, scorch and infirm welding shall be forbidden.
3. At single-seam welding, the lap width shall be no less than 60mm for roofing project and no less than 100mm for underground project. As to double-seam welding, the reserved lap width depends on different welding machines. 
4. The closing end of sheet is fastened by special trim strip, with maximum distance of no less than 900 mm between nails. Sealing compound and cement mortar are used for final sealing and covering.




Storage and Delivery

1. Products of different kinds and specifications shall be placed separately without being mixed.
2. Avoid being exposed to the sun and ventilation is very important.
3. The product should be stored below 45℃,with height less than 5 layers. Avoid contact with acid, alkali, oily objects and organic solvent. 

4. When transported, avoid being tilted or pressed. Tarpaulin is needed if necessary.
5. Under normal storage and delivery conditions, one-year storage lifetime from day of production.




ü  What’s the difference EPDM waterproof material and waterproof PVC coating?-----The difference is mainly in the form of (1)Various one is a coil fabric,one coating  liquid (2) Material EPDM rubber,PVCplastic(3)different resistance to aging :EPDM waterproofing materials have optimalest resistance to aging,use a certain number of years(excluding renewables)(4) the construction of waterproof membranes overlap,coating construction without duplicating the overall peformance is good,but the film thickness of the coating is controlld by brushing time.Thus,it is suggested that the selected depending on different locations and environments.
