Waterproof sheets for tunnels with a water-tight structure! Heat welding is also possible, adapting to various conditions.
"Fitliner" is a chemically adhesive waterproof sheet developed for water-tight (non-drainage type) tunnels using the New Austrian Tunneling Method (NATM). By chemically bonding the surface of the waterproof sheet to the lining concrete, it prevents water leakage from damaged areas of the waterproof sheet from spreading. Additionally, made from flexible and highly stretchable EVA resin, it conforms well to uneven sprayed surfaces. With a thickness of 2.0 mm, it withstands high water pressure and excels in thermal welding on-site. 【Features】 ■ The special surface EVA resin chemically bonds with concrete ■ Prevents water leakage from spreading widely without meandering at the interface between the waterproof sheet and the lining concrete ■ Compatible with thermal welding to standard tunnel waterproof sheets ■ The signal layer is laminated, making it easy to detect damaged areas during construction *For more details, please refer to the PDF document or feel free to contact us.
