CALCIS is a contractor in engineering geophysics and offers engineering geological consultancy. These services are used to understand ground for projects. For more details : http://www.calcis.eu

Projects carried out in Europe, Middle East and Africa. Using geophysics and engineering geology in different stages of projects: desk study, design, planning, site investigation, supervision of works. Main activities include:• Geophysical investigations to map geological conditions of the site of future tunnel and natural dam, to assess rippability along future highway or dynamics soil properties prior to building construction• Data synthesis of site investigation along a High Speed Train route• Landslide: soil investigation of the slope instability• Quarries: reserve estimation, overburden thickness, compacity of deposit, karstic area, exploration for extension• Engineering geological supervision of site investigations prior to the construction of quay wall• Coordination and supervision of several borehole campaigns and geotechnical tests prior to harbour extension, dredging, civil engineering projects• Offshore magnetic survey to localize UXO’s, pipes and shipwrecks prior to dredging works • Site investigation for dredgeability assessment (Harbour development projects)

Main activities, carried out in Europe, include: • Acquisition and interpretation of magnetic surveys to localize UXO’s, pipes, wrecks prior to dredging (Harbour development projects) • Pollution and rippability assessment of an old industrial waste depository for a drainage network• Borehole geophysics for detection of water bearing cracks ahead a tunnel face• Foundation study in karstic area for different bridges, detection and localisation of old mines galleries along a High Speed Train route

LGIH service at University of Liège. More than 50 projects in Europe in the following main activities:• Acquisition, Processing, Interpretation, integration of geological, geophysical and geotechnical data for engineering projects• Boreholes and in situ geotechnical tests supervision• Groundwater exploration and supervision of well drillings, pumping and tracer tests; Mathematical models for flow and pollution problems;• Site investigation of waste disposal sites and planning of remedial works
