                               PVC waterproofing membrane

Product Overview:

PVC waterproofing membrane is  made by putting antioxidant, antiager, plastizer, ultraviolet light absorber into polyvinyl chloride. Tecchniques kneading, mixing, extrusion and calendering.

Classification:

1. 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).

Features:

1. With superb resistance to aging and chemical corrosion.

2. With great tensile strength and elongation.

3. With good performance in temperature and weather resistance.

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

5. Simply applied in construction.

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

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




Scope Of Application:

The product is applied in waterproof, anti-permeability, anti-pollution engineering in fileds of civil buildings, roads, railway, caves, tunnels, water conservancy projects, chemical industry, environmental protection, and landfill etc.

Performance Index:

Product Performance Conforms to Polyvinyl Chloride Waterproof Sheet (GB12952-2011)

Construction method:

According to features of different projects,different methods are applied, such as mechanical fastening, gasket fastening, border adhibiting and full adhesion method. The joint is welded by hot-air welding machines.

★ Mechanical fastening

This method applies to roofing projects, especially waterproofing treatment on metal roofs. The number of fastening components and distance between each other is calculated on practical circumstances to resist uplift pressure from wind. Specially designed metal gasket and tapping screw are used for fastening, which is applicable to different base courses, fast, safe and reliable.

★ Gasket fastening

This method applies to side walls of underground engineering, caves, tunnels and vault. The application is not affected by degree of smoothness, humidity of the base course. PVC gasket is used to strengthen sheets' adaptability to deformation of the base course, which makes construction easy and convenient.

★ Border adhibiting

This method applies to floors and roofs of basement and buildings, and also roofs for vehicles and human travelling. Adhesive and fastening are not applicable. After pavement is finished, hot-air welding machine is used to weld joints of sheets. Geotextile can be added as protective layer. Free from influence of environment, the cost of construction will be reduced.

★ Full adhesion

It's applied to side wall of basement, basement roofing. The non-woven of PVC sheet (Type L) can be bonded tight by special adhesive with the base course, playing the role of insulation, protection and buffer.

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 counts form production date.


Attention:

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.
