Cast walls – there are two types: reinforced concrete cast walls made with Stein heavy-duty or Trech Cutter system (with structural role) and plastic walls (with protection against water infiltration)
Small diameter category – the following types of special foundations: micropiles, anchors and injection techniques such as jet-grouting, compaction or compensation injection.
Microtunnels – tunnels drilled horizontally with diameters ranging from 600mm to 3500mm in difficult ground conditions using TBM equipment.
Ground improvement – columns of granular material (crushed stone or ballast) realized in GEOPIER® system (RAP, GCC) and vertical drainage (wick drains).
Environmental work – aims to address a wide range of issues such as bioremediation, soil remediation and groundwater control.
