High drainage sheet for FILM construction method

Over 50 times the drainage capacity of general-purpose waterproof sheets! Capable of responding to the increase and changes in future groundwater emergence locations.

The "FILM Method High Drainage Sheet" is a waterproof sheet designed for tunnels that respond to groundwater. It has more than 50 times the drainage capacity of general-purpose waterproof sheets, significantly reducing clogging caused by free lime and flowing sediment, and providing excellent crack prevention for concrete. By achieving water diversion treatment across the entire surface and perimeter of the back 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】 ■ More than 50 times the drainage capacity of general-purpose waterproof sheets ■ Achieves water diversion treatment across the entire surface and perimeter of the back of the lining concrete ■ Can respond to the increase and changes in future groundwater emergence points due to rainfall and changes in water flow ■ Excellent in reducing clogging caused by free lime and flowing sediment, and in preventing concrete cracks *For more details, please refer to the PDF document or feel free to contact us.
