As a result of simplifying materials and processes... shortened construction period! Reduced waterproofing costs!

Easy construction ensures quality while shortening construction time, reducing costs, and increasing profits! The advancements in workability, environmental performance, and economic efficiency have been recognized, and it has been registered in NETIS.

In the typical modified asphalt waterproofing torch method, the process begins with the installation of a ventilation sheet, followed by the application of a sand-coated sheet, where the entire back surface is heated and melted using a torch burner. This process requires a high level of skill and places a significant burden on the workers. OS-sheets have mechanized the entire torch sheet heating process at the construction site in a factory setting, which has improved quality and reduced the burden on workers, while also eliminating one step in the construction process. The torch work at the construction site is now limited to the sheet joint areas, allowing for approximately a 90% reduction in the use of open flames compared to the typical modified asphalt waterproofing torch method, significantly lowering CO2 emissions and the burden on workers. As a result, the speed of waterproofing construction has increased, and stable quality improvements have been achieved while considering the natural and working environments. OS-sheets enhance productivity with a smaller workforce, shorten construction periods, and enable more waterproofing projects to be completed. Additionally, the OS-sheets waterproofing system has a simple material composition, making inventory management easier and reducing transportation costs. By simplifying materials and processes, various costs can be reduced, allowing for the generation of additional profits.
