Tunnel Liner is a corrugated steel solution used for the construction of tunnels without the need for digging ditches or earthworks. This avoids interrupting the activities on the surface, while the work is being carried out, reducing costs and inconveniences, whether in urban or rural areas.

Its installation is done by digging manually or mechanically, and then reinforced with the Tunnel Liner plates which are installed from the inside thanks to its folded wings. This system is ideal for works such as drinking water networks, sewers, vehicular or pedestrian crossings. Likewise, the mining field, it is highly competitive for tunnels beneath stockpiles, ventilation tunnels, and rainwater conduction tunnels.

  • Structural resistance: Its structural resistance allows it to support important loads for use in bridges and underpasses. Whereas, it is flexible and elastic which provides high resistance to earthquakes
  • Economic: It is highly competitive - regardless of its diameter, shape or required load type.
  • Durable: Steel is a high strength material which can be complemented with a Magnelis finish, and other coatings such as galvanized and epoxy.
  • Efficient Transport: Because it is composed of snack plates, it can be transported to remote and difficult to access areas.
  • Easy assembly: The installation of the structure does not require specialized personnel or equipment.
  • Ecological and reusable : The structures can be easily disassembled and transported in case of relocation. Meanwhile, steel is 100% recyclable which makes it an environmentally friendly solution.
