PVC Waterproofing Membrane

What is PVC waterproofing membrane?

Polyvinyl chloride (PVC) waterproofing membrane is a high-performance polymer waterproofing sheet. PVC resin as the main raw material is added with plasticizer, anti ultraviolet agent, anti-aging agent and stabilizing agent Processing aids such as additives are used to produce polymer waterproofing membranes through extrusion molding. Product amplitude Width of 2 meters, thickness of 1.2,1.5,1.8,2.0mm, 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 product lifespan far exceeds that of ordinary waterproof materials, and the entire waterproof system has a long lifespan.

Divided by the product composition: homogeneous non-composite membranes (code H), with fiber composite backing sheet (code L), fabric reinforced sheet (code P), Sheets of single-layer and laminated sheets with fibre felt or fibre as reinforced layers are supplied in our company.

What are the basic features of PVC waterproofing membrane?

▪ 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, leaving moisture on the base layer,Moisture is easily expelled

▪ 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.

What is PVC waterproofing membrane used for?

• Roof waterproofing,such as industry and civil roof.
• Underground waterproofing,example:reserior,dam,channel and cellar.
• Tunnel,expressway,bridge,landfill and artificial lake.

Technical Data Sheet

PVC waterproofing membrane meets the GB12952-2011 standard, with its main physical and mechanical properties

​

Construction technology

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 area 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.
