This flexible structure is made of corrugated steel, which is composed of sheets that allow away arming from the inside.

The Tunnel Liner is made of hot-dipped Galvanized materials.

It offers the best solution when it is not possible to excavate or interrupt traffic on the surface. This solution generates significant savings in terms of time, manual labor and land movement and also reduces noise and air contamination on the work site.

Applications and uses

• Coatings for damaged reinforced concrete structures.

• Coatings for highway and railway tunnels.

• Coatings for shafts and wells.

• Access wells.

• Conduits or mains to protect interior pipes.

• Tubular Conduits under highways, streets and railways.

• Tunnels for conveyor belts.

• Sewers, rain drains and wastewater collectors.

• Walkways for pedestrians, cattle, material transportation and public service networks.

Advantages

Require less excavation and filling.

Prevent damage to pavement and public service networks.

Do not produce settling on roads or highways.

Eliminates the need to build under an open ditch, which reduces land movement costs.

The galvanized steel sheets are highly durable in aggressive environments and require limited maintenance.

Formats

Tunnel Liners are circular and come in a wide range of sizes to suit the needs of different projects. Their thicknesses vary between 2.5 mm to 6.5 mm. The minimum diameter is 1.200 mm while the maximum diameter is 5 to 6 meters.
