Siphon Drainage Waterproof Board

Siphon Drainage Waterproof Board is a multifunctional polymer geotechnical material integrating active siphon drainage, waterproofing and anti-seepage functions, widely used in tunnel, basement, municipal and water conservancy engineering. It has comprehensive reliable performance for long-term on-site application. It boasts outstanding waterproof and anti-seepage performance. Its compact polymer structure has low porosity and no water permeable gaps, featuring a low permeability coefficient to stably block various water bodies, with no water leakage under long-term high water pressure. It owns excellent chemical stability to resist acid, alkali and salt corrosion, and modified types can withstand organic solvent erosion. Added anti-aging additives endow it with great weather resistance, keeping intact structure and stable impermeable performance outdoors with slow performance attenuation. It has superior mechanical properties including high tensile strength, tear strength and elong…
