Statewide Geotechnical (Aust) Pty Ltd

Statewide Geotechnical (Aust) Pty Ltd, established in 1987 through a merger of Vic Drill and Statewide Geotechnical Services, is a leading Australian engineering and geotechnical testing laboratory with over 30,000 site investigations completed. Operating from their primary facility at 17-20 Summer Lane, Ringwood, Victoria, the company provides comprehensive soil and rock testing services across the eastern seaboard including Victoria, New South Wales, Queensland, and South Australia. The laboratory is NATA-accredited under ISO/IEC 17025:2017 (Accreditation #20648, Site #24753, certified 28 June 2023) and employs over 20 personnel including certified engineering geologists, soil technicians, and geotechnical engineers.

The company's testing services encompass a comprehensive range of geotechnical analyses essential for construction, mining, and infrastructure projects. Soil classification and analysis services include moisture content determination, particle density measurement, sieve analysis, and Atterberg limits testing (liquid and plastic limits). Compaction testing covers both standard and modified effort procedures, whilst bearing capacity assessments and soil stabilization evaluations support foundation design and earthwork specifications. Advanced testing includes rock strength evaluation, point load analysis, soil resistivity testing for corrosion assessment, and hydrometer analysis for fine-grained soil characterization. All testing methodologies conform to Australian Standards (AS 1289 series for soil testing, AS 4133 for rock testing) and ASTM protocols, ensuring alignment with internationally recognized quality standards.

In addition to laboratory testing, Statewide Geotechnical operates a specialized drilling division providing integrated site investigation capabilities. Diamond drilling services include PQ, HQ, NQ, and Triple Tube configurations for core sample recovery in mineral exploration and geotechnical applications. The drilling fleet encompasses reverse circulation, aircore, and hammercore drilling systems, supplemented by excavator-mounted test pitting for shallow foundation investigations. In-situ testing methodologies deployed during drilling operations include Standard Penetration Testing (SPT), pressuremeter testing, Dynamic Cone Penetrometer (DCP) testing, and vane shear testing. Monitoring bore installation and instrumentation setup support long-term groundwater and settlement monitoring programs for major infrastructure projects.

Groundwater assessment and management form a critical service component, encompassing groundwater monitoring bore construction, pumping tests for aquifer characterization, permeability testing, and hydrogeological assessment. The company specializes in tight-access and sensitive site drilling, utilizing compact, track-mounted, and multipurpose drilling rigs suitable for urban environments and restricted access locations. Pre-purchase assessments and desktop studies provide clients with preliminary site characterization before detailed investigation programs commence. These integrated capabilities position Statewide Geotechnical as a trusted partner for consulting engineers, architects, utility companies, government authorities, and national utility operators requiring comprehensive site investigation and testing services.

The company serves diverse industries including construction (residential and commercial), mineral exploration and mining operations, infrastructure and utility development, and environmental assessment and remediation projects. Statewide holds CMPA (Construction Material Processors Association) Preferred Supplier status, reflecting industry recognition of quality and reliability. The laboratory's experienced technical team and state-of-the-art equipment enable delivery of testing and investigation services meeting rigorous Australian and international standards. With operations spanning multiple eastern Australian states, the company provides accessible testing and drilling services to major construction and infrastructure clients, government bodies, and the mining and exploration sector.
