EVA PVC Plastic Foundation Waterproofing Membrane , PCM Single Side Membrane

EVA PVC Plastic Foundation Waterproofing Membrane , PCM Single Side Membrane

PCM is made from the copolymer resin polymer (HDPE, LDPE, EVA, PVC, the ECB, TPO) homogeneous sheet as the main body of the waterproof layer, with the coating which has creep function rubber asphalt adhesive materials on the layer, and cover polymer self-adhesive waterproofing materials which made of silicone oil anti-sticking isolation membrane, according to the need of polymer composite fabric sheet on strengthening enhanced polymer waterproofing materials.

Product features

1. Single layer membrane, the double line of defense. PMC membrane is compounded with polymer sheet and self-adhesive membrane, combining two kinds of waterproof material’s advantages. Greatly improving the puncture resistance, weather resistance, self-healing, high and low temperature resistance and other properties. Physical properties are more excellent, chemical performance are more stable
2. Paving in advance and pasting versa technology. Self-adhesive layer and concrete have good adhesive power, solve the basement floor, side wall, tunnel’s waterproof and pasting problems.
3. Lap joint is reliable, it can solve tunnel’s construction problems in winter. PMC membrane’s lap joint not only can self-adhesive but also can be all-welded. Although viscous material is bad when the temperature is very low in the winter, you can adopt all-welded lap way, thus it does not affect the integrity and quality of coiled material waterproof layer.?
4. The construction method are varied. You can choose according to site conditions: wet laid method, wet laid method, hang way, mechanical fixed or other construction method; Construction is flexible and effect is optimal.
5. Good self-healing capability. PCM membrane with rubber resilience and strong self-adhesive, the nails and other sharp objects with good wrapped function, the membrane can heal itself after puncture by nails or sands when construction. Especially suitable for planting roof.

6. Super \"water lock\" function. The power of the PCM membrane and the base plane is strong, the leakage caused by membrane’s breakage can be limited in the local scope, avoid causing membrane failure as a whole.
7. The requirements of the base plane is low, convenient and quick. PCM membrane’s construction is not affected by the flatness of base plane, no need to do the leveling layer, also can construction on damp base surface. It is not affected by the weather and it can greatly shorten the construction period, saving the cost
8. Safety and environmental protection. PCM membrane and supporting products do not contain organic solvents, use flame homework phenomenon does not exist in the construction site, the whole construction process to eliminate the potential hazard to the environment, also save the energy.
9. The membrane can be up to 2.2 m wide, reducing lap construction time, to speed up the construction progress.

Scope of application

Suitable for all kinds of industrial and civil architecture roofing, basement, tunnels, Bridges, tunnels, reservoirs, civil air defense projects, subway, planting roofing, etc. Especially suitable for high construction railway, high construction tunnel waterproof engineering.

Construction technology process

PCM polymer composite adhesive membrane construction technology has the following several kinds of methods:
Dry laid method:
Base plane treatment→Brushing treatment agent at the base plane →Node details treatment (attached layer)→Laid PCM membrane→half header treatment→The waterproof layer inspection→protective layer’s construction(Due to the site condition is complex, this process is not recommended)
Wet laid method:
Base plane treatment→Scraping coat and preparation polymer cement slurry (sand) →Node details treatment (attached layer) →Laid PCM membrane→half header treatment →The waterproof layer inspection→protective layer’s construction
Paving in advance and versa pasting method:
Base plane treatment→Node details treatment (attached layer)→Reference plane elasticity positioning→Laid PCM membrane →Remove the isolation membrane→ pouring concrete

Hang and versa pasting method(Commonly used in tunnel construction):

To install, drilling and hang the door→Ready the membrane→Hang and fixed the membrane→Construction the next piece membrane→Membrane and membrane welding→Pasting double-sided self-adhesive sealing strip→Remove isolating membrane from membrane’s surface→ Acceptance checks
Mechanical fixed method
Clean up base plane→Ready the membrane→Shoot nails to fix the membrane→Sealing the nails’ part→Paste and lap the membrane’s long and short side →The node enhance processing→Acceptance
