Specialised Testing

Capabilities Lab-Testing Macquarie-Geotech-Oct-2024-WEB-49

We are equipped with the latest in advanced testing equipment to perform specialised soil mechanics testing, offering advanced analyses such as one-dimensional consolidation tests, UU, CU and CD triaxial tests. We also analyse swell-collapse properties, permeability and direct shear strength to evaluate soil behaviour under varying conditions. These tests provide critical insights into soil strength, stability, and drainage properties, essential for effective geotechnical engineering and project design.

Our Expertise

Capabilities Lab-Testing Macquarie-Geotech-Oct-2024-WEB-71

Soil Consolidation

To predict potential ground movement and facilitate foundation design we undertake soil consolidation by oedometer analysis, enabling the analyses of soil behaviour and one-dimensional consolidation properties (Cv, Cc, C, Mv and Ca) under different loadings.

Soil Triaxial Strength

Our fully automated GDS-advanced triaxial testing systems precisely analyse soil mechanical properties, crucial for predicting material behaviour and shear strength parameters (c’ and Ф') under varying stress conditions (UU, CU, CD and UCS). Our standard pressure volume controllers can apply pressures of up to 2 MPa.

Soil Permeability

Tailored to meet the unique demands of each project, our advanced permeability systems can precisely measure hydraulic conductivity/permeability (k) in the range of 10-5 to 10-12 m/s with volumetric accuracies up to 1mm³. For fine grained, materials of low permeability we utilize the constant head triaxial flexible wall permeameter method. For materials such as DGB20 or other well graded Sandy Gravels with little or no fines, we utilise the falling head method for a measurement range of 10-7 to 10-9 m/s.

Soil Shear Strength

Direct shear testing is undertaken on cohesive or non-cohesive samples of an undisturbed or disturbed nature to determine the drained shear strength under normal stress conditions (peak & residual). The data points obtained can be utilised to determine internal angle of shearing resistance and cohesion values.
