The Service
Accurate Data for
Confident Design
Accurate soil characterisation is the foundation of every reliable geotechnical assessment. Without precise, site-specific soil parameters, structural and civil engineers are left to estimate — and in geotechnically complex North Queensland, estimation carries real risk. PGI Geotechnical Group conducts a comprehensive range of in-situ field tests and laboratory analyses to precisely quantify the strength, compressibility, plasticity and permeability characteristics of soils on your site.
Our field testing capability includes Standard Penetration Testing (SPT), Dynamic Cone Penetrometer (DCP) testing, vane shear testing for soft cohesive soils, falling-head and constant-head permeability testing, and California Bearing Ratio (CBR) testing for pavement and earthworks projects. All field work is conducted by qualified technicians under the direct supervision of experienced geotechnical engineers.
Laboratory testing is carried out through NATA-accredited facilities, ensuring your results meet the quality and traceability requirements of Australian Standards and engineering design practice. Our engineers interpret every test result in context — providing not just data, but actionable geotechnical parameters your design team can rely on.

When You Need It
Soil Testing Drives
Better Outcomes
Foundation & Structural Engineering
Your structural engineer needs quantified soil bearing capacity and stiffness parameters to design footings that perform safely under load — not conservative assumptions that drive unnecessary construction cost.
Pavement & Earthworks Design
You're designing a road, car park or hardstand and need CBR values and compaction characteristics to specify an appropriate pavement structure without over-designing for unknown ground.
Fill Placement & Compaction Verification
Your contractor has placed fill on site and you need independent testing to verify compaction meets specification — protecting the project owner from the consequences of premature settlement.
