2 SADE Group SADE was founded in 1918 and is specialised in the design, construction, rehabilitation and maintenance of networks (for water, energy and telecoms) and the structures associated with them (civil engineering) for all public, industrial and private-sector clients. Since 1971, its has been handling atypical works in all types of environments, as well as projects requiring the use of innovative techniques. The expertise of the is based on: its knowledge and mastery of trenchless network construction and rehabilitation techniques, its complementary skills in civil engineering, its made-to-measure solutions, logistics capacities and methods developed by its R&D and Equipment departments, its experienced teams with over 280 specialised staff, its constant search for environmentally-friendly construction solutions. The boasts in-house resources for studies and for developing and designing specific equipment, and devises technical solutions that are tailored to each project in France and abroad, in full synergy with all the SADE Group entities. UNDERGROUND WORKS The is a leading player in the design and construction of underground facilities linked to hydraulic infrastructures and dry networks, and implements a wide range of specific techniques: n Tunnel boring machines with installation of arch liners in diameters from 2,500mm to 5,000mm for technical galleries or collectors n Microtunnel boring machines in diameters of 500mm to 2,500mm, including for distances in excess of 1,000m and along curves, with drilling spoil removal n Excavation and traditional techniques for galleries and wells down to great depths n Pipe jacking and horizontal drilling to cross obstacles and install piping at great depths

3 Services n Design and build n Rehabilitation (renovation, replacement) n Dismantling n Asbestos removal n Work in confined spaces n Coordination of the different participants n Project management n Research and development into techniques tailored to meet specific requirements CIVIL ENGINEERING In the stormwater and wastewater treatment and transport chain, underground or semi-buried civil engineering structures are necessary for storage or to fight against flooding. To build these facilities, the combines its skills in civil engineering and pipe laying. n Stormwater and water treatment basins n Drinking water reservoirs n Containment walls n Lifting and pumping stations n Technical galleries n Sea and river works

4 NON-MAN-ENTRY NETWORKS REHABILITATION For non-man-access facilities, the employs a wide range of rehabilitation processes to provide the right solutions tailored to the pathologies of the hydraulic structures (drinking water, sanitation, industry). n Slip lining, with or without an annular space n Continuous or partial close-fit lining n Manhole rehabilitation n Bursting n Multifunction robot n Winding process MAN-ENTRY NETWORKS REHABILITATION The many underground networks built in the last century are ageing, subject to chemical attack and affected by land subsidence... In the great majority of cases, extending their lifespan is a better investment than rebuilding them. To do so, the uses the following rehabilitation techniques: n Sprayed coatings, carbon fibre n Structural liners n Grout injections for foundation treatment, coating or stonework regeneration n Full and partial-section prefabricated shells
