TX sheet method [Water leakage prevention work (drainage work) using polyethylene sheets]

Excellent drainage function and easy installation due to the rib effect on the back of the sheet.

The "TX Sheet Method" uses a rigid polyethylene sheet (TX Sheet) to cover areas of water leakage in the lining concrete, allowing for linear or surface drainage. Due to its thin thickness of 4mm, including ribs, it can be installed without affecting tunnel accessories. Additionally, the rib effect on the back of the sheet forms a drainage layer, providing excellent drainage functionality. Anchoring can be performed over non-anchored materials, ensuring excellent workability, and it can be applied across differences in elevation such as corners and edges depending on the shape of the tunnel. 【Features】 ■ Excellent drainage effect The rib effect on the back of the sheet forms a drainage layer, resulting in superior drainage functionality. ■ No aging deterioration The sheet is highly resistant to chemicals, unaffected by acids, alkalis, or organic solvents, and has good weather resistance with no aging changes. ■ Installation possible after inspection and repair Depending on the deformation of the tunnel, the TX Sheet Method can be applied after inspection and reinforcement. ■ Excellent workability and cost-effective Using Hawk and KB anchors allows for anchoring over the secured materials, making it a highly workable and economical method.
