- Dry Density Moisture Content Relationship (2.5kg, 4.5kg or vibrating hammer)
- Natural Moisture Content
- Particle Size Distribution (wet and dry sieve)
- Particle Size Distribution (sedimentation analysis)
Performance Tests:
- California Bearing Ratio (CBR) Test
- Oedometer Consolidation Test (Mv, Cv &e/log P)
- Permeability Test
Shear Strength Tests:

Our Geotechnical Engineers at Sub Surface will provide a site specific Laboratory Testing Schedule based on the strata encountered, the type of development and the proposed foundation Design for each Ground Investigation to enable a Technical Report to be written.
Contamination Testing can also be included as part of your Laboratory Testing and Ground Investigation.
