Effective for areas with a high risk of water leakage! Chemical adhesive waterproof sheet for tunnels.
The "Fit Liner Type-S" is a waterproof sheet for tunnels that has been specially processed on the surface of an EVA sheet (thickness 0.8mm) to chemically bond with fresh concrete. It was developed for drainage-type tunnels to prevent water pathways at the interface between the waterproof sheet and the lining concrete, thereby preventing water leakage from the lining. The surface of the black sheet has a white layer that acts as an interlayer, allowing any damage to the waterproof sheet during construction to reveal the black color of the damaged area within the white surface, providing a signal layer function that makes it easy to visually detect damage. 【Features】 ■ Developed for drainage-type tunnels to prevent water leakage from the lining ■ Signal layer function that makes it easy to visually detect damage ■ Effective in areas where manual welding with hot air is frequently used, increasing the risk of water leakage *For more details, please refer to the PDF document or feel free to contact us.

basic information
【Water Stop Mechanism】 To firmly adhere to concrete, even in the event of partial damage, high water tightness is achieved. This prevents water from splashing at the interface between the sheet and the concrete cover, and even if the sheet is damaged, it will maintain high waterproof performance as long as the damaged area does not align with the concrete crack. 【Signal Layer】 The white layer (signal layer) that is completely molded into the black waterproof sheet makes it easy to detect damage to the sheet by exposing the internal black color in the event that the sheet is scratched. *For more details, please refer to the PDF document or feel free to contact us.*
