Who We Are
Tongliang Waterproof & Leak Sealing Co., Ltd. (brand: Tongliang Waterproofing; Chinese name: 莱州市沙河镇同亮防水材料厂) is located in Heiyangshan Village, Shahe Town, Laizhou City, Shandong Province. We are a specialized enterprise in the field of underground engineering leak sealing, and our mission has always been “to end leakage in underground structures.”
We tackle the common seepage problems found in tunnels, underground parking garages, water reservoirs, basements, underground utility tunnels, metro systems and civil air-defense works. With our proprietary, high-performance sealing materials — AS grout, high-strength specialty grout, specialty epoxy resin and more — together with advanced electro-osmotic and pressure-grouting technology, we provide a diversified system of waterproofing solutions.
From slight dampness to pressurized flowing water, our engineers diagnose the true water path and apply the method that stops the leak at its source — not merely on the surface.
