Our commitment

The result of various analyses reveals a scenario in which a series of quick interventions is required. Multiple damages impacting both the economy and the social base of countries: this is the reason why we aim to implement projects with high social and economic impact value. One project currently being developed offers a solution for the final lining of tunnels. Our ETLR technology – Extruded Tunnel Lining Regeneration – features a method (patented by HINFRA) based on horizontal slip-forming of special concretes, thanks to which caps are regenerated by extrusion. This process includes the design of a fully automated processing train that is able to deliver a final product with a guaranteed long service life.
