Laboratory Testing
From Sampling to Results - You're Covered at Every Stage
Earthworks & Compaction
Earthworks and compaction testing confirms that construction materials and placement methods meet design and specification requirements. Geotest Services undertakes field and laboratory testing during construction to verify compliance with relevant Australian Standards and TfNSW requirements, providing confidence that earthworks are performing as intended.
Our Earth Works and Compaction Services Include:
• AS3798 Level 1 – Testing & Certification
• Bulk Earthworks Conformance
• Pavement Compaction Testing
• TfNSW (RMS) Projects
• Dynamic Cone Penetrometer (DCP) testing
Soil & Rock Mechanics
Soil and rock mechanics testing provides information on the strength, deformation and durability of soils and rock to support design and construction decisions. Geotest Services undertakes laboratory testing using appropriate methods and equipment tailored to project requirements. Results support informed assessment of material performance and engineering decision-making.
Our Soil & Rock Mechanics Services Include:
• Strength & Mechanical Testing
• Hydraulic Testing
• Point Load Strength Index
• Unconfined Compressive Strength
Materials Conformance
Materials conformance testing provides assurance that concrete, soil, rock and aggregate meet project specifications and relevant standards. Geotest Services undertakes testing through a NATA-accredited laboratory, using Australian Standards, TfNSW/RMS, ASTM, and ISRM methods, to support confidence in material performance and compliance across construction works.
Our Material Conformance Services Include:
• Concrete Compressive Strength
• California Bearing Ratio (CBR)
• Plastic Index & Linear Shrinkage
• Particle Size Distribution (Grading)
• Shrink Swell Index
• Atterberg Limits
• Linear Shrinkage
• Emerson Class Number
• Aggregate Conformance
• Hydrometer testing
Thermal Resistivity Testing
Thermal resistivity testing is essential for understanding how soils, backfills, and construction materials transfer heat, directly impacting the performance of underground infrastructure such as power cables, pipelines, and geothermal systems. Geotest Services delivers accurate laboratory and in-situ testing to support design, compliance, and quality assurance across civil, electrical, and energy projects, helping optimise material selection and ensure long-term asset performance.
Our Thermal Resistivity Testing Services Include:
• In-Situ Thermal Resistivity Testing
• Thermal Resistivity Testing
• Thermal Dry-Out Curve Analysis
• Backfill and Bedding Material Testing
• Concrete and Grout Thermal Testing
• Quality Assurance (QA) Testing During Construction
• Material Suitability and Compliance Assessment
Clear, reliable laboratory testing supporting design, compliance and construction quality
Providing confidence in materials performance at every stage of development.
