Our experienced Geotechnical Engineers and Engineering Geologists perform Geotechnical Investigations to obtain information on physical properties of soil and rock in order to design earthworks and foundations for proposed structures. A geotechnical investigation usually includes surface and subsurface exploration of a site.

Surface exploration can include geologic mapping and geophysical methods or it can be as simple as a geotechnical professional walk around the site to observe the physical conditions.

Subsurface exploration usually involves soil sampling by boring or excavating of trial pits. The investigation might include in-situ tests or laboratory tests of the soil samples retrieved.

Some of the in-situ tests that can be performed by our experienced engineers are:

  • Standard Penetration Test – SPT
  • Cone Penetration Test – CPT
  • Permeability Test
  • DCP Test
  • CBR
  • Plate Bearing Test

Some of the laboratory tests are:

  • Particle Size Distribution (dry, wet, hydrometer)
  • Atterberg Limits
  • Moisture Content
  • Specific Gravity
  • Particle Density
  • Triaxial Tests
  • Shear Box Test
  • Shear Vane test
  • Penetration test
  • Oedometer tests (Consolidation, swelling pressure, swelling measurement, permeability)
  • Permeability tests
  • Proctor and California bearing ratio
  • Point Load Test
  • Chemical Test
