High drainage waterproof sheet

Excellent drainage function under harsh conditions, with high compressive strength, impact resistance, and flexibility!

The "High Drainage Waterproof Sheet" is a waterproof sheet designed for tunnels that accommodate groundwater. It has 40 times the drainage capacity of general-purpose waterproof sheets, significantly reducing clogging caused by free lime and flowing sediment, and is excellent at preventing cracks in concrete. By achieving water diversion treatment on the entire back and perimeter of the lining concrete, it can respond to the increase and changes in future groundwater emergence points due to rainfall and changes in water flow. 【Features】 ■ The waterproof sheet is constructed with a three-layer structure and features a three-dimensional mesh body. ■ Achieves 40 times the drainage capacity of general-purpose waterproof sheets. ■ Clogging due to free lime and flowing sediment is less likely to occur. ■ Rich in compressive strength, impact resistance, and flexibility, it exhibits excellent drainage functionality under harsh conditions. ■ Effective in preventing cracks and more economical compared to the use of drainage materials. *For more details, please refer to the PDF document or feel free to contact us.
