Our Services

Our in-situ testing services offer essential information on soil composition, strength, and stability, assessing the suitability of sites for design and construction. We provide Standard Penetration Tests (SPT), dynamic cone penetrometer (DCP) testing, hand shear vane (HSV) testing, cone penetration testing (CPT), and undisturbed push tubes (<75mm) for high-quality soil samples.

Using specialised instruments, we monitor groundwater behaviour, soil pressure, and structural movement. This includes packer testing, groundwater standpipe and vibrating wire piezometer installations, inclinometers, and extensometers.

Our testing capabilities include Light Weight Falling Weight Deflectometer (LWFD) testing, plate load testing, and Benkelman Beam testing to assess soil and pavement strength.

Seismic surveys are fundamental to subsurface mapping and can determine bedrock depth, identify faults and assess soil properties, while also enabling the calculation of engineering parameters such as Young’s Modulus, Shear Modulus, and Poisson’s Ratio.

Electrical techniques are employed to assess the conductivity properties of the subsurface. These methods provide insights into soil composition, groundwater presence, and geological structures.

Magnetic surveys help map variations in the Earth’s magnetic field, aiding in identifying subsurface anomalies, such as different rock types, mineral deposits, or buried structures. These surveys are crucial for mineral exploration and environmental studies.

Ground Penetrating Radar(GPR) is a non-invasive and high-resolution method used to image subsurface structures and detect anomalies. It provides detailed two-dimensional and three-dimensional images of the subsurface, aiding in structural investigations, pavement assessments, and void detection.

Downhole imaging involves capturing images of the borehole walls and subsurface structures using Optical and Acoustic Televiewers (OTV & ATV) to assess geological characteristics, identify fractures, evaluate lithology, and provide a detailed understanding of the subsurface environment.

Wireline logging is the use of advanced technologies within the borehole to extract as much data as possible. This includes Gamma readings, in-situ P&S wave logging, fluid temperature and conductivity and more.

Electromagnetic techniques are a quick, cost-effective way of extensively mapping a site’s near surface conductivity. This provides information on soil profile, depth to bedrock, and buried features.  

Macquarie Geotechnical offer a comprehensive range of geotechnical drilling methods for both land and overwater-based applications. Combining cutting-edge technology with highly experienced and trained operators, we deliver efficient and cost-effective drilling solutions that can be tailored to the project's requirements.

Not only does Macquarie Geotechnical offer industry-leading operators, but we also offer class leading Sonic Drills that are at the forefront of the industry in innovation, safety and technology. Providing low impact, high capacity, small footprint rigs and truck and tracked support equipment.

Macquarie Geotechnical are experts in commercial, production, mining, construction, rural and domestic water bores.

Our experienced operators hold currency of accredited water well licenses ranging from class 1 to 3.

Macquarie Geotechnical team members are experts in geotechnical data management and contribute to the AGS 4 AU working group. We’ve developed field logging tools to ensure consistent data collection, meeting AGS 4 AU requirements, including extended component fields in GEOL.

Macquarie Geotechnical has developed robust internal data governance standards that extend the AGS data format. These ensure data is collected in a systematic and consistent manner that is machine interpretable and a foundation for modern digital engineering workflows.

We are creating a network of platforms to manage geotechnical and project data in line with the “single source of truth” (SSOT) concept. This ensures data is stored appropriately and exchanged seamlessly between applications, enabling meaningful interpretation and utilisation.

Our laboratories deliver comprehensive soil testing services, providing detailed analysis and classification of soil types, including moisture content, particle size, and Atterberg limits, while also assessing dispersion, reactivity, and bearing capacity.

Equipped with advanced testing systems, we perform specialised soil mechanics analyses such as triaxial tests, direct shear, and one-dimensional consolidation to evaluate soil strength, stability, and drainage under diverse conditions.

Rock mechanics testing provides critical data on compressive strength, deformability, tensile strength, shear strength, and sound velocity, enabling precise geological and engineering decision-making.

Field density testing and AS 3798-compliant inspections ensure accurate compaction measurements and reliable assessments of subgrade and fill materials for quality control in construction projects.

Concrete testing services encompass sampling, slump tests, and compressive strength analysis to verify durability and workability, supporting the success of construction projects.

By conducting a wide array of aggregate tests, including particle size distribution, wet-dry strength, and crushing value, we ensure materials meet industry standards and are optimised for construction performance.

Through chemical testing of soil and construction materials, we provide essential insights into pH, resistivity, and chloride or sulfate content, ensuring suitability for construction and environmental needs

NATA-accredited onsite laboratories providing essential testing for earthworks, concrete, aggregates, and more — delivered where projects need them most.

Understanding the geology and ground conditions is crucial to an effective exploration campaign. Our expert team can advise on the appropriate exploration method, including the latest imaging, mapping, geophysical and drilling techniques to ensure you get the data you need.

Production of 3D geological models using the latest industry software such as Leapfrog Works that can be shared with the client viewer platforms to help you understand your deposit and communicate geology to external stakeholders, while allowing JORC-compliant reserves and resources assessments to be reported on.

Proper pit design and phasing is essential to optimise the whole-life performance of the operation, maximising reserve recovery while avoiding costly double-handling of overburden or excessive haul distances. Macquarie Geotechnical can provide whole-life phasing and annual mining plans to optimise pit development and comply with regulations, while providing the necessary support to operations teams to ensure designs are realised. 

Drawing on over 20 years of experience undertaking geotechnical investigation and material testing, Macquarie Geotechnical can provide expert advice on rock quality and geological influences on site. Using our in-house testing experts, we can assist in developing and implementing a bespoke quality management system to help optimise your production and maintain consistent product quality.

Macquarie Geotechnical is uniquely positioned to assist with complex challenges where bespoke support and advice is needed on a project or ongoing basis, for example implementing digital geological databases, incorporating geotechnical risks into Safe Work Method Statements or landform designs for remedial plans.
