Customer Question & Answer


As unique composite sheet, which is composed of one thick HDPE backing layer, an aggressive pressure sensitive adhesive and trafficable weather resistant protective granular coating, the unique membranes realizes firm bonding to poured concrete,so that prevents water ingress or migration.










Remark: Specification can be customized as requirement.

3.Use scope:Used for underground,tunel ,subway waterproofing project,not for roofing.


Forms continuous and reliable physical bond to the poured concrete against it, which prevents water migration and reduces possibility of being affected by below-grade structure settlement
2.Loosely-laid onto slabs:requiring no priming or fillets
3.Trafficable weather resistant adhesive side:
Can receive pedestrian or traffic immediately after application and makes convenient for subsequent placing of reinforcement, site contamination is easy to be removed.

4.Superior physical & chemical property:
Shock and puncture resistance, can withstand heavy duty loading, protect structure from salts and sulphate attack

5.No butt joints
All joints have bonded "selvedge for accurate and easy overlap, to increase leak protection

5. Installation Guidance:

1. Substrate preparation

Remove all protrusions and clean up the substrate 

2. Install membrane(loosely laid)
Loosely lay the membranes onto the substrate (ensure the adhesive side to face upward) 

3. Rolls Overlapping
3.1 Cut edges
Tear down the selvedge release film, adhere adjacent membranes together, then using tools to press overlapping area to insure firm bonding (if necessary, heat the overlapping area, then proceed with overlapping) 

3.2 Roll end laps
Position special tape strip of appropriate sizes over the lap of beneath membrane, then melt the strip using hot-air welding gun and immediately overlap the adjacent membranes together. Press firmly over lapping area to achieve seamless joints.
