Waterproof Sheet for Tunnels

Waterproof Sheet for Tunnels is a dedicated polymer impermeable material designed for tunnel anti-seepage construction, equipped with comprehensive advantages to meet strict underground engineering standards. It delivers outstanding waterproof and impermeable effects. Its compact polymer structure has low porosity and zero water-permeable gaps. With a low permeability coefficient, it reliably blocks all forms of water and avoids leakage even under long-term high hydraulic pressure. The sheet maintains stable chemical properties to withstand erosion from acid, alkali and salt solutions. Specially modified versions can resist damage from organic solvents while retaining intact structure and anti-seepage capacity over decades. Blended with anti-aging additives, it gains great weather resistance, showing slow performance decline during long-term outdoor exposure. It possesses excellent mechanical indicators including high tensile strength, tear resistance and elongation at break. Variou…
