Rose Testing Pty Ltd

Rose Testing Pty Ltd is a Sydney-based geotechnical engineering consultancy and materials testing laboratory headquartered at Unit 25/29 Sunblest Crescent, Mount Druitt NSW 2770. Founded by a multidisciplinary team of engineers and professionals with over a decade of combined experience in both the United States and Australia, the company delivers practical, reliable ground engineering solutions and accredited laboratory testing services for residential, commercial, and infrastructure projects across New South Wales. Rose Testing holds ABN 86 646 802 173 and operates with a clear mission to meet and exceed client expectations while delivering projects on time and within budget.

The laboratory's core materials testing capability covers a comprehensive range of soil and aggregate characterisation services. These include Maximum Dry Density testing, California Bearing Ratio (CBR) determination, Grading and Particle Size Distribution (PSD) analysis, Plasticity Index (PI) and Linear Shrinkage measurement, and Emerson Class testing for soil dispersion behaviour. For rock materials, Rose Testing performs Point Load Testing of rock core and Uniaxial Compressive Strength (UCS) testing, providing essential mechanical property data for foundation design, slope stability analyses, and tunnelling or excavation projects. These tests are conducted to Australian Standards and industry protocols, supporting geotechnical engineers, civil contractors, and project managers in making informed design decisions.

Rose Testing provides a full suite of concrete and asphalt testing services critical to quality assurance on construction and civil infrastructure projects. Concrete services include compressive strength testing of hardened specimens, concrete core testing from in-situ structures, sampling of fresh concrete, and slump testing to verify workability. For asphalt materials, the laboratory conducts density testing, air voids determination, and core testing, enabling contractors and project supervisors to verify pavement layer compliance with project specifications and Australian road authority requirements. These services support both new construction quality control and post-construction forensic investigations.

The laboratory extends its scope into environmental and analytical testing, addressing the increasingly important regulatory requirements around hazardous materials and contaminated land. Rose Testing offers asbestos identification for hazardous materials assessments, contaminated land site investigations, and acid sulfate soil (ASS) assessments. The team is also experienced in material classification for waste and fill materials, including verification and classification of Virgin Excavated Natural Material (VENM), Excavated Natural Material (ENM), and General Solid Waste (GSW) — classifications that are mandated under NSW Environment Protection Authority guidelines for the beneficial reuse of excavated materials on construction sites. These services serve developers, principal contractors, and environmental consultants navigating NSW Planning and EPA compliance.

Geotechnical site inspection is a significant service stream at Rose Testing, covering the full lifecycle of earthworks and pavement construction. The team conducts Level 1 Conformance inspections for earthworks, in-situ compaction testing of earthworks and pavement layers, excavation stability inspections, subgrade assessments, test roll inspections, and pile inspections. Field testing methods include Plate Load Testing to determine subgrade bearing capacity and Benkelman Beam Testing for pavement deflection measurement under load — techniques widely used by road authorities and civil contractors to assess pavement structural performance. These inspection services are provided by qualified geotechnical engineers and technicians with direct project-site experience.

Beyond laboratory and field testing, Rose Testing offers geotechnical investigations and construction engineering services. Subsurface exploration programs are designed and executed to support lot classification (AS 2870 residential footing classification), pavement investigations, and field testing for a range of project scales. Engineering assessment services encompass working platform design for heavy plant, bearing capacity assessments, excavation stability assessments (including temporary works), and pavement design. Certification services are also available, making Rose Testing a single-source provider for both investigation data and the engineering sign-off that clients often require before construction can proceed.

Rose Testing has achieved NATA (National Association of Testing Authorities, Australia) accreditation for 30 tests spanning aggregates, rocks, soil, concrete, and asphalt — a milestone that demonstrates conformance with the international ISO/IEC 17025 standard for testing laboratory competence. NATA accreditation is recognised by regulators, local councils, Roads and Maritime Services (now Transport for NSW), and private project owners as the benchmark for laboratory quality in Australia. The accreditation covers the full range of the laboratory's core geotechnical and construction materials testing, giving clients confidence that results are technically rigorous, traceable, and defensible.

Serving the construction, infrastructure, roads, energy, and sustainability sectors across New South Wales, Rose Testing is positioned as a growth-oriented laboratory that combines the technical rigour expected of a NATA-accredited facility with the responsiveness of a specialist consultancy. The company's vision is to become the leading soil testing solution provider in NSW, and its client base includes builders, developers, civil contractors, environmental consultants, and government infrastructure programs. With a team grounded in both USA and Australian engineering practice and a commitment to raising industry standards, Rose Testing offers clients a credible, professional partner for geotechnical and materials testing needs from investigation through to construction completion.
