PVC waterproofing membrane

PVC waterproofing membrane

Products Description

PVC waterproofing membrane with polyester fibers is a kind of high performance polymer waterproof material. The main raw material is PVC and the enhanced PVC membranes are with the incorporation of special additives, anti-aging components, and the inner layer of polyester fabric. It is made by the advanced equipment and advanced production.

Advantage

1. Long life, anti-aging,   roofing materials can be used more than *0 years, underground up to *0 years.

2. Tensile strength, high elongation, heat treatment of small size changes.

3. A good low temperature flexibility and adapt to environmental temperature change is good.

4. Resistance to root penetration, and can be made into green roofs.

5. Anti-perforation is good.

6. Convenient for construction, welding, solid and reliable and environmentally friendly non-polluting.

7. Resistance to chemical corrosion resistance, applicable to special occasions.

8. Has good plasticity, corner detail treatment convenient.

9. Easy maintenance and low cost.

 

Scope of application

PVC waterproofing membrane is widely used in building roof, metro, culvert, tunnel, planted roof, waterproofing and drainage systems, ponds, reservoirs, irrigation systems, light steel roof and other fields.

1. Large-scale underground structures.

2. Surface of concrete slabs for planting.

3. For roads, rails, subway tunnels projects.

4. For reservoirs, canals, dams and other water conservancy projects.

Construction technology

1. Tunnels, bridges should use polymer sheet welding lap joints. Firstly, pre-paved polymer sheet side of polymer self-adhesive composite waterproof membrane toward the base, and fix it with dedicated pieces of machine, double lap weld seam welding machine should be used for lap joints. Tear off insulation paper, band reinforced concrete directly, self-adhesive waterproof membrane will adhere to the main body of concrete structure closely to achieve full adhesion.

2. General building underground projects should use self-adhesive overlap method. Basement bottom: prepaying the membrane on cushion firstly(polymer sheet face down), tear off isolation paper of self-adhesive waterproof layer, structural concrete, the membrane will anti-stick to the concrete structure to form dense waterproof system.

3. Basement side wall, surface of concrete slabs for planting: attach the self-adhesive material side to the base surface directly, tear off reserved isolation paper of lap joints self-adhesive side. Side wall shall be fixed with dedicated pieces of machine.

4. Half header treatment: weather horizontal half header or vertical half header, which should be sealed with sealant, membrane in the elevation without groove half header, it shall be fixed with metal straps firstly, then seal the top hole of metal straps and fixed screw with sealant.
