Tunnel Lining Anti-Seepage Waterproof Sheet

Product Overview: Tunnel Lining Anti-Seepage Waterproof Sheet The Tunnel Lining Anti-Seepage Waterproof Sheet is a high-performance polymer membrane specially customized for tunnel lining anti-leakage construction. It can be matched with Bentonite GCL, Drainage Board and Erosion Control Mat to form complete multi-layer geotechnical systems with waterproofing, drainage and slope protection capabilities. Core Advantages This sheet features ultra-low water permeability to thoroughly block underground seepage water and prevent tunnel water leakage. It possesses high tensile elongation and excellent low-temperature flexibility, which can adapt to lining deformation without cracking. When laid together with Drainage Board, it quickly diverts accumulated groundwater to reduce hydrostatic pressure on the membrane. Combined with Bentonite GCL, it forms dual anti-seepage barriers to enhance long-term anti-leakage reliability. Erosion Control Mat covered on tunnel portal slopes protects the…
