We perform a wide range of tests on soil and groundwater samples. A list of routine tests performed can be found below. Please contact us for specific requirements and a price list.

Classification Tests

• Moisture Content
• Atterberg Limits (Liquid and Plastic Limits)
• Particle Size Distribution (Wet & Dry Sieves, Hydrometer Tests)
• Bulk Density
• Specific Gravity (set of two tests)
• Laboratory Permeability

Shear Strength Tests

• Undrained triaxial test - single 30mm or set of three 38mm diameter
• Undrained triaxial test - single or multi-stage 100mm diameter
• Functional triaxial test - set of 3 38mm diameter specimens
• Effective Shear Strength
• Shear Box

Consolidation Tests

The oedometer consolidation test is used for the determination of the consolidation characteristics of soils of low permeability. It invloves applying a sequence of loading to a specimen and measurements made over a period of time. The results can give an indication of the amount of settlement, typically of a low permeability clay soil, which is likely to occur over time.

• Oedometer Consolidation
• Consolidation/Dissipation in triaxial cell

Compaction Tests

• BS 2.5kg Compaction
• BS 4.5kg Compaction
• BS Vibrating Hammer Compaction
• California Bearing Ratio

Chemical Tests

• pH in soil and groundwater
• Water soluble Sulphate content in soil and groundwater
• Organic Content
