Subsurface Investigation

QST Geotechnical delivers comprehensive subsurface exploration services to accurately characterize soil, rock, and groundwater conditions, providing the technical foundation required for industrial-grade engineering design.

Soil Borings

High-precision exploratory drilling to retrieve continuous soil samples and define subsurface stratigraphy with absolute accuracy.

Groundwater Observations

Strategic installation of monitoring wells and piezometers to track critical water table fluctuations and flow dynamics.

Test Pits

Direct visual inspection of shallow subsurface conditions with bulk sample collection for comprehensive laboratory validation.

In-situ Testing

Advanced field measurements including SPT, CPT, and vane shear to assess real-time soil strength and engineering properties.

SITE EVALUATION

Comprehensive evaluation of soil and subsurface conditions to support site development, foundation design, and permitting requirements.

Laboratory Testing

Rigorous analytical testing of recovered samples to establish precise index properties, shear strength, and settlement behavior.

Field Testing & Analysis

Precision on-site diagnostics and material evaluation to ensure structural integrity and compliance with rigorous engineering standards.

Soil Compaction Testing

Nuclear gauge density testing and sand cone methods to verify optimal moisture-density relationships.

Concrete Sampling

Fresh concrete testing including slump, air content, and casting of cylinders for compressive strength verification.

Asphalt Core Extraction

Precision coring to determine pavement thickness, density, and composition for quality assurance.

Bearing Capacity

Dynamic cone penetrometer (DCP) and plate load testing to assess subgrade strength and foundation suitability.

Environmental Sampling

Soil and groundwater extraction for contamination analysis and environmental site assessments.
