Dezhou Rongchuang Environmental Protection Materials Co., Ltd. - PVC Anchor Discs (PVC Anchors) are geomembrane fixing accessories specially designed for tunnel waterproofing projects. They are professionally welded from high-strength PVC discs and screws, and are mainly used for fixing and installing PVC geomembranes in tunnels and underground projects. They are firmly bonded to the geomembrane through hot-melt welding to form a stable seepage-proof fixing system, ensuring the long-term reliability of the waterproof structure.

Product Features

• Matching Material, Strong Welding: Utilizing PVC raw materials from the same source as PVC geomembranes, seamless fusion can be achieved through hot air welding, resulting in excellent seepage prevention and eliminating leakage risks.

• Stable Structure, Uniform Stress Distribution: The large-sized disc design increases the stress-bearing area, dispersing the tension on the geomembrane and effectively preventing membrane detachment and bulging.

• Corrosion and Aging Resistance: Resistant to acids and alkalis, and moisture, adaptable to the complex underground water environment of tunnels, with a service life synchronized with the geomembrane.

• Convenient Construction, High Efficiency: Can be directly hot-melt welded to the geomembrane, eliminating the need for complex accessories and significantly improving tunnel construction efficiency.

• Strong Adaptability: Customizable disc size and screw length to adapt to different thicknesses of PVC geomembranes and tunnel construction requirements.

Application Areas

• Tunnel Engineering: Waterproofing systems for highway tunnels, railway tunnels, and subway tunnels

• Underground Engineering: Underground parking garages, integrated utility tunnels, and civil defense projects

• Water Conservancy Engineering: Seepage prevention for reservoirs, culverts, and sewage treatment plants

• Others: Geomembrane seepage prevention projects for landfills, tailings ponds, etc.
