Geotechnical Engineering

Geotechnical engineering combines various engineering activities related to soil and rock mechanics. Encompassing the study of mechanical and physicochemical properties of coil and their interaction with surrounding structures, geotechnical engineering is primarily based on geology. All aspects of civil engineering structures call for a supporting soil or bedrock adaptation system, which can be assessed by WSP’s geotechnical design experts.


WSP’s geotechnical design engineers have gained valuable experience in geotechnical engineering easily applicable to the design and construction of earthworks (cofferdams, embankments, breakwaters, dykes and dams) and the design of shallow or deep foundations for civil engineering structures (dams, buildings, bridge infrastructures, wind turbines, wharves, electrical substations and power transmission lines, road and railway structures, etc.). Our team offers solutions in excavation, backfilling, drainage, in situ soil improvement and slope stability.

Thanks to the projects carried out by our multidisciplinary teams, WSP has been able to acquire an outstanding know-how of the latest technologies leveraged to increase project success. The geotechnical team is highly skilled and possesses all required expertise to carry out our client’s projects with efficiency.

Our geotechnical experts provide support to designers in the following areas of civil engineering:

  • Building foundations (shallow foundations, raft foundations, caissons and piles) (at static or dynamic conditions) for the industrial, road (bridges, etc), commercial or institutional sectors;
  • Road, railway, and airport infrastructures;
  • High structures foundations (communications towers, transmission towers, and wind turbines);
  • Electrical substations;
  • Slope stability;
  • Earthfill structures (roads, dykes and dams);
  • Tailings sites, waste disposal sites;
  • Marine structures;
  • Excavation, retaining structures and shorings;
  • Soil drainage and dewatering systems;
  • Soil in situ improvement (dynamic compaction, vibratory compaction, etc);
  • Dam safety evaluations;
  • Soil liquefaction analyses.
