Rendel's capability in the geotechnical sector covers a wide variety of expertise and techniques ranging from the identification of ground related risk to the design of heavy foundations and tunnelling and expert witness and forensic engineering services.

We provide services over a range of (on-shore, near-shore and off-shore) project sizes and a variety of aspects.

Our geotechnical experience can be grouped under seven main sectors

  • Site assessment, desk studies and monitoring
  • Heavy engineering (foundations, tunnelling, basements/sub-surface works, retaining structures)
  • Buildings (foundations, basements, gas and waterproofing, monitoring, damage assessment)
  • Slopes and cliffs
  • Ports and maritime geotechnics including land reclamation
  • Earthworks and ground improvement
  • Technical expertise services (technical advice, FEM, value engineering, risk assessments, expert witness and forensic engineering)


  • Desk studies, geomorphologic surveys, site/ground investigations and ground models, monitoring, environmental studies, contaminated ground
  • Ground and groundwater related risks identification, assessment and management
  • Deep and shallow foundations design for major civil infrastructures (e.g. bridges, industrial) and buildings
  • Basements
  • Retaining walls and structures
  • Slope and cliffs assessment, stabilisation, development and management
  • Submerged and bored tunnels
  • Geotechnics for maritime and river engineering and ports
  • Hydraulic reclamation and dredging
  • Ground improvement
  • Highway and railway earthworks
  • Ground movement, settlement prediction and monitoring
  • 2D and 3D FEM numerical modelling
  • Rock engineering (including cliff inspections)
  • Environmental and building monitoring
