Asphalt waterproof membrane

Bituminous Waterproof Sheet

The waterproof sheet material, which is rollable, is manufactured by dipping and coating the body materials such as original paper and fibrous felt with asphalt, and then spreading powdered, granular, or sheet-like materials on the surface.

Roofing membrane, referring to both fibrous and non-fibrous membranes. Membranes made by impregnating thick paper or materials like glass fiber cloth, asbestos cloth, and cotton-linen fabrics with petroleum asphalt are known as fibrous membranes; while those mixed with materials like asbestos and rubber powder, then pressed into roll form, are called rolled membranes, also known as non-fibrous membranes.

Rolled materials with a rubberized coating, including oil paper and asphalt felt.

PVC Waterproof Membrane – Polyester Fiber Reinforced Polyvinyl Chloride (PVC) Waterproofing Rolls

Polyester-reinforced PVC (PVC) waterproof membrane is a thermoplastic PVC sheet material, which is made by integrating the double-sided PVC plastic layers with a polyester fiber reinforcing rod through a special extrusion coating process, forming a polymer sheet. The advanced formula of the PVC plastic layer combined with the mesh structure of the polyester fiber fabric provides the sheet with dimensional stability and a low thermal expansion coefficient. This enhances the long-term performance of the sheet when directly exposed to the natural environment. Product specifications: Width: 2-2.1m, Thickness: 1.2mm-2.0mm, Length: Over 20m. Installation method: Hot air welding to ensure the quality of the seams.
