Reinforced PVC Waterproofing Membrane, Built to Outlast the Roof It Covers

Xiaolong: A Seasoned Reinforced PVC Fabricator for Global Waterproofing Projects

Water can seep in through any cracks in the roof, basement walls, or water storage facilities. Poor-quality membranes or poorly welded seams are usually the root cause of this type of damage.

Xiaolong manufactures reinforced PVC waterproofing membranes designed to provide a long-term seal against these gaps. Each roll of waterproofing membrane consists of a PVC polymer matrix, a polyester reinforcement layer, and an adhered polyester non-woven backing. This construction ensures that the membrane not only maintains its performance on the day of installation but also withstands the test of time, even when subjected to cracks, deformation, and prolonged exposure to water.

Every batch undergoes factory testing before shipment, and all orders are packaged in standard export packaging. As a result, distributors and construction contractors receive not just samples, but products that fully comply with the specifications outlined in the technical data sheet. For buyers with project-specific requirements, Xiaolong offers custom thicknesses, widths, and colors, as well as OEM/ODM packaging services.

Core Advantages of Xiaolong Reinforced PVC Membrane

Fleece-Back Non-Woven Backing

· Polyester nonwoven fleece is integrally bonded to the membrane, giving adhesive and mechanical fastening a stronger surface to grip.

· Spreads structural stress evenly across the sheet, reducing the risk of local tearing at fixing points.

Optional Root-Resistant Grade

· A root-resistant formulation is available for green roof and planted terrace projects, blocking penetration from plant roots.

· Suited to long-term landscaped roof systems where the membrane cannot be re-accessed easily.

Robust Hot-Air Welded Seams

· Sheets are joined by hot-air welding, forming a continuous, watertight bond between rolls.

· Weld strength is matched to the base membrane, so the seam is not the weak point of the installed system.

High Elongation, Cold-Weather Flexibility

· High elongation lets the membrane absorb structural movement and thermal expansion without cracking.

· Stays flexible at low temperatures, so installation is not limited to warm-season weather windows.
