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
- 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
