SPECIALIST TECHNIQUES

TRENCHLESS TECHNIQUES

SADE possesses all the skills, know-how and high-performance equipment required touse the technique best suited to the features of the projects. The techniques andmethods are defined after studies, in accordance with soil types, undergroundcongestion and the immediate surroundings of the work site.

SADE has determined that all its business lines should be committed to sustainable development.

The group’s environmental undertaking is evidenced in its day-to-day action, with a “clean site charter”, themeasurement of the carbon footprint of its worksites via the group’s certified Carbon 6 software, and prio-rity given to recycling (road surfacing materials, excavated materials), either on-site or nearby.

Prevention and safety are two of SADE’s absolute require-ments: protection of staff, users and local residents, and pre-vention of risks relating to the presence of other networks.This determination has borne fruit: the group’s industrial acci-dent frequency and severity rates are well below the averagefor the profession.
