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 can handle groundwater. It has 40 times the drainage capacity of standard waterproof sheets, significantly reducing clogging caused by free lime and flowing sediment, and is excellent in preventing concrete cracks. 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 paths. 【Features】 ■ The waterproof sheet has a three-layer structure with a three-dimensional mesh body installed. ■ Achieves 40 times the drainage capacity of standard waterproof sheets. ■ Clogging due to free lime and flowing sediment is less likely to occur. ■ Rich in compressive strength, impact resistance, and flexibility, it demonstrates excellent drainage function under harsh conditions. ■ Effective in preventing cracks and is more economical compared to using drainage materials in combination. *For more details, please refer to the PDF document or feel free to contact us.
