PRODUCT DESCRIPTION         
Polyvinyl chloride (PVC) waterproof roll is a kind of polymer waterproof sheet with excellent performance. PVC resin is used as the main raw material to add processing aids such as plasticizer, anti ultraviolet agent, anti-aging agent and stabilizer to produce polymer waterproof roll by extrusion. The product has a width of 2 meters, a thickness of 1.2,1.5,1.8,2.0mm, and a standard length of 20m (special specifications can be customized). The product quality is reliable and the construction is convenient. Due to the use of a unique product formula, the lifespan of this product far exceeds that of ordinary waterproof materials, and the entire waterproof system has a long lifespan.

BASE TREATMENT

Roofing Engineering (GB50207-2002)
▪ The strength, thickness, moisture content and other indicators of the construction base layer should meet the design requirements of national standards before PVC waterproofing membrane construction can be carried out.
▪ Determine the direction and sequence of laying the planned roll material, and arrange it naturally on the base layer according to the outline of the waterproof layer. Smooth and straight, without bending, overlap according to the required overlap width specified in the specifications.
▪ Fix according to the selected fixing method, such as mechanical fixing method, full adhesion method, strip adhesion method, etc.
▪ The overlapping parts of waterproof membrane welding should be wiped clean and dry, and hot air welding should be used. During welding, the welding nozzle should be at a 45 ° angle to the welding direction, and the pressure roller should be parallel to the welding nozzle and maintain a distance of about 5mm. The welding edge should have a bright colored molten paste seeping out, and there should be no burning phenomenon.
▪ The end of the coil is fixed with a pressure strip, sealed with sealant, and tightly sealed with cement mortar.
▪ The entire waterproof part of the project has been fully inspected and treated for quality.
Underground Engineering (GB50208-2002)
▪ The strength, thickness, moisture content and other indicators of the construction base layer should meet the design requirements of national standards before PVC waterproofing membrane construction can be carried out.
▪ Reasonably select the construction method according to the different waterproof parts, and specifically implement the GB50208-2002 standard.
▪ The overlap width of the coil should be 100mm, and the lower coil should press down on the upper coil.
▪ Multiple welds should be used for lap joints, and the welding width of a single weld should not be less than 100mm.
▪ The laying of PVC waterproofing membrane should be smooth and firmly fixed to the foundation, without sagging, tension, or damage. After inspection and confirmation, the construction of the next process can proceed.

PRODUCT FEATURES

▪ Strong chemical corrosion resistance and suitable for special occasions.
▪ Has good plasticity and convenient and fast processing of corner details.
▪ Easy maintenance and low cost.
▪ The light colored surface reflects ultraviolet radiation, and the surface of the coil absorbs less heat and has a low temperature.
▪ The roll material has good water vapor diffusion, and the condensate is easy to release. The moisture and humidity left at the base layer are easy to discharge.
▪ Long service life and aging resistance.
▪ High tensile strength, high elongation, and small size change after heat treatment.
▪ Good low-temperature flexibility and adaptability to changes in environmental temperature differences.
▪ Good root penetration resistance, can be made into a planting roof.
▪ Good perforation resistance and impact resistance.
▪ Easy to construct, with minimal overlap in width and width, weldable, and sturdy and reliable.
