Polymer waterproof materials are one of the chemical building materials, with environmental protection and excellent physical and chemical properties, widely used in residential buildings, industrial and commercial buildings, water conservancy projects and underground engineering and other building waterproof engineering. Beixin waterproof polymer waterproof roll is made of synthetic rubber, synthetic resin or the blend of the two as the base material, adding the right amount of chemical additives and filler, using the processing technology of rubber or plastics such as mixing, extrusion or calendering can be rolled into sheets of waterproof material.

Product Specification:


The product adopts PVC resin as the main raw material, adding plasticizer, stabilizer, antioxidant, anti - aging agent and other additives made of waterproof materials. The material has the characteristics of high strength, large elongation, but also has the advantages of good flexibility, can be used naked, at the same time has the ability of root resistance waterproof material.



Cold sticking method:The use of special supporting glue, the membrane paste on the base of the construction method, divided into full bonding or local bonding method. Finally, the membrane lap edge welding can be compacted.
Mechanical fixation method:The construction method of connecting the membrane with the base by mechanical fasteners. The membrane lap edge welding can be compact.

Construction Method

Machinery welding joint:The use of climbing welder for welding, suitable for large area construction, quick construction.
Hand welding joint:Hand-held welder is used for welding, suitable for detail construction and small area construction.Manual welding can be divided into three steps: "spot welding", "pre-welding" and "solid welding" to ensure the welding effect.Spot welding: used to fix the membrane and prevent the membrane from shifting. When spot welding, gently press the membrane surface with the tip of the gun.Pre-welding: it can seal, prevent hot air from blowing away, and can't reach the welding temperature.Solid welding: weld the two rolls of membrane into a whole.
