Rough-Surface Geomembrane for Tunnel Waterproofing
Our tunnel-specific rough-surface geomembrane utilizes advanced spray-roughening technology to create a textured surface that significantly enhances adhesion with tunnel concrete linings. Manufactured from high-elastic HDPE material, it effectively adapts to tunnel structure deformation while preventing cracks and water seepage.
Application Scenarios
Specifically engineered for waterproofing applications in highway tunnels, railway tunnels, and underground utility tunnels. Installed between the tunnel primary support (such as shotcrete) and the secondary concrete lining, this geomembrane serves as a reliable waterproof barrier to prevent groundwater infiltration.
The textured surface ensures secure adhesion with concrete, preventing separation caused by tunnel deformation. The material's durability provides excellent resistance to damage from construction machinery and rock fragments, making it ideal for demanding tunnel construction environments.
