Our fleet of brand-new machines and equipment is at your disposal.
The civil engineering workforce in our Networks Division put their proven expertise into use on all kinds of work, trenchless or otherwise, including network dismantling, laying and maintenance in new, existing and utility tunnels, shafts, and accessible sewer installations.
Our teams specialize in a wide range of complex techniques including shaft sinking, rocket and percussion drilling, the auger drilling technique (with or without preguidance) and micro and mini TBMs. We design and manufacture our own tools and develop our operational processes in compliance with budget, deadlines and environmental standards. These network operations can be carried out as part of any type of civil engineering project.
We carried out earthworks and civil engineering operations to link up Vitry to the MIN incineration plant in Rungis.
We bored two 1,200-diameter shafts in a 230 m curve, using the mircotunnelling technique, under SNCF tracks and a departmental road.
3.3 km of cast-iron pipelines involving 230 m of microtunnelling.
