The "FILM Method" is a construction technique that smooths the waterproof sheet installation surface and utilizes wide sheets, offering many advantages. With two types of lineups, 6.36m and 10.52m in full width, it meets a wide range of needs. In addition to reducing the amount of welding work on-site and minimizing the risk of welding defects, the waterproof sheet becomes smooth, which improves the workability of rebar assembly and concrete placement for the lining, among various other features. 【Features】 ■ Improved quality of lining concrete ■ Enhanced water-stopping ability ■ Improved workability ■ Wide range of needs met with two types of lineups *For more details, please refer to the PDF materials or feel free to contact us.

The "F-S Bolt" is a long steel pipe injection mirror bolt that can be constructed at a low cost compared to non-steel materials. Since the steel pipe has slits, it can be easily cut and removed as the face advances, allowing for construction with a hydraulic tunnel boring machine. It has a high shear strength compared to other materials, providing tensile resistance against face collapse, as well as expected shear resistance. 【Features】 ■ Can be constructed at a low cost compared to non-steel materials ■ The slits in the steel pipe make cutting and removal easy as the face progresses ■ Being made of steel, it allows for easy separation from spoil during cutting and removal ■ Injection of polyurethane and cement-based materials is possible, and it can also be used as a drainage hole ■ By adjusting the presence of slits, it can also be constructed as a small-diameter long-length advance support *For more details, please refer to the PDF document or feel free to contact us.
