Tunnel liner is a system for tunnel construction based on corrugated steel sheets, whose design allows for reinforcement from the inside, minimizing impact on the surface.

Tunnel Liner allows for the rapid, safe, and cost-effective construction of sewers, ventilation tunnels, chimneys, shafts, and other utility services, such as gas and electricity networks. Tunnel Liner structures are bolted together and can be adjusted to suit project requirements.

It is a versatile system for tunnel construction that integrates large sizes, rapid installation, easy transportation, and minimal impact on the surface.
