Works by trenchless methods are in the origins of our company. We are proud to say we have developed the Tunnel Liner process, with broad application, from the construction of road tunnels to different uses in sanitation works. We are acknowledged as the most traditional company executing works by these processes in Brazil. This experience enables us to execute complex works, such as tunnels in rocks, underground pedestrian and vehicle passages, sewage interceptors and collectors, water ducts, and road access.
