Geotechnical Laboratory Testing

California bearing ratio 

• California bearing ratio testing determines the strength of soil in relation to pavement design and construction.

Particle size distribution 

• Particle size distribution testing determines the distribution of soil particles, which is important for geotechnical engineering and soil science.

Atterberg limits 

• Atterberg limits testing determines the water content at which fine-grained soils transition from a plastic to a liquid state.

Standard compaction 

• Standard compaction testing measures the maximum dry density and optimum moisture content of a soil sample.

Modified compaction 

• Modified compaction testing is used for soils with larger particle sizes and provides a higher level of compaction.

Nuclear density 

• Nuclear density testing determines the density and moisture content of soils, which is important for quality control during construction.

Set-up and maintenance of a quality testing regime to assist the quarry industry 

• Establishes a reliable and effective testing system to ensure high-quality materials for various construction purposes.  

Degradation tests

• Determines the durability of aggregates under various environmental and stress conditions.  

Strength/crushing tests

• Measures the compressive strength and crushing resistance of rock and aggregates to ensure they meet industry standards.  

Index tests 

• Evaluates the properties of aggregates, such as particle size, shape, and density, to ensure they meet specified requirements.

Foreign materials 

• Detects and quantifies the presence of contaminants, such as clay, organic matter, and other materials that could affect the quality of aggregates.

Flakiness  

• Evaluates the proportion of flat and elongated particles in aggregates to ensure they meet industry standards.

Unsound stone 

• Determines the soundness of aggregates by identifying the presence of any cracks or weaknesses that could impact their durability and longevity.

Thermal resistivity testing 

• Measuring the rate of heat flow through soil, rock and other materials.

Permeability – falling head, constant head and flexible wall 

• Determining the ability of a material to transmit fluids.

Total and effective stress testing 

• Determining the strength and deformation characteristics of soil under different stress conditions.

Point load index testing 

• Measuring the strength of rock and core samples.

Oedometer consolidation testing 

• Measuring the rate and magnitude of compression in clay soils.

Shrink swell testing 

• Measuring the volume changes in soil due to moisture content variations.
