Polymer Self-Adhesive Film Waterproof Membrane (Pre-applied)

Polymer Self-Adhesive Film Waterproof Membrane It takes polymer sheet (HDPE) as the substrate, with a single-sided high-performance self-adhesive film layer covered by granular anti-sticking coating. It is installed by the pre-laid and reverse-bonding method. Before the post-cast concrete sets, under gravity, the concrete gradually cross-links with the adhesive layer of the membrane. During cement curing, stronger physical adsorption is formed, so that the membrane is firmly bonded to the post-cast concrete and resists delamination.

PVC Polyvinyl Chloride Waterproof Membrane

PVC Polyvinyl Chloride Waterproof Membrane PVC waterproof membrane is a thermoplastic PVC sheet with advanced formulation suitable for hot welding, engineered for long-term weather resistance and stable performance. Its physical properties are reinforced by a tough weft-inserted polyester fabric, encapsulated within a thick PVC substrate. The smooth surface of the PVC sheet enables full-surface fusion and permanent welding, forming a monolithic, watertight roof assembly. PVC membranes can be used for both adhered and mechanical fastening systems.

Plastic Corrugated Pipes

Prestressed plastic corrugated pipes are manufactured from HDPE. They are mainly used for duct forming of tension bars in post-tensioned prestressed concrete structures. Featuring good sealing performance, no slurry leakage, high ring stiffness, low friction coefficient, ageing resistance, electrolytic corrosion resistance, good flexibility, and resistance to damage by vibrating pokers. Their innovative connection design facilitates easier on-site jointing. These pipes are widely applied in long-span tension projects such as highways, railways, bridges, slopes and high-rise buildings.
