Materials Testing
In-house laboratory and field testing across the project lifecycle, determining geotechnical parameters for design and verifying that ground conditions and construction materials meet design requirements.
Laboratory Testing
Test Pit ExcavationASTM D2487
Test pits allow direct soil logging and recovery of disturbed samples for classification, supporting site characterization and assessment of fills, reclamation and shallow foundation conditions.
Index TestingASTM D6913 · D4318 · D2216 · D7928
Sieve analysis, Atterberg limits, moisture content and hydrometer testing classify soils and establish key index properties used in geotechnical assessment and design.
Compaction & Density TestingASTM D698 / D1557
Laboratory compaction testing establishes moisture-density relationships and target densities for earthworks, pavement subgrades and engineered fills.
Rock Strength TestingASTM D7012
Recovered rock samples are tested for unconfined compressive and, where required, triaxial strength to support rock characterization and foundation design.
Sampling From CPT Rigs
Disturbed and undisturbed samples can be recovered beyond practical test-pit depths using our CPT rigs. DS-44 samples support classification and chemical testing, while Shelby tube samples support consolidation and strength testing.
Field QA/QC Testing
In-Situ CBR Testing (DCP)ASTM D6951/D6951M
Our Vertek Smart DCP provides real-time CBR estimates for rapid assessment of pavement subgrades, compacted fills and earthworks performance.
Sand Cone Density TestingASTM D1556/D1556M
Sand cone testing verifies in-place density and compaction against specified requirements for engineered fills, subgrades and earthworks.
Construction Supervision & Documentation
Geotechnical supervision during critical earthworks provides documented verification of ground conditions, material placement and compliance with design requirements, reducing rework and construction-stage uncertainty.
