Australia's largest independently owned Construction Materials Testing company. NATA accredited labs across the Eastern Seaboard — soil, concrete, aggregate, geotechnical.
Australian Soil & Concrete Testing is the largest independently owned Construction Materials Testing company on Australia's Eastern Seaboard. For over three decades we've backed some of the country's most demanding infrastructure, residential, and energy projects.
Our network of NATA accredited laboratories extends from Townsville in North Queensland through New South Wales and into Victoria — with mobile lab capability for remote and large-scale projects anywhere on the continent.
All testing conducted to Australian Standards in our accredited labs. Results your certifier and council will accept first time.
Standard reports within 2–3 business days of site visit. Express next-business-day service available for time-critical projects.

From a single residential slab classification to ongoing CMT support for major infrastructure corridors — we have the capability and capacity.
AS 2870 compliant site classification reports for residential slabs and footings. Council-ready, QBCC licensed classifiers.
Comprehensive laboratory and field soil testing to Australian Standards. Covering CBR, compaction, particle size, and more.
Field and laboratory concrete testing including compressive strength, slump, density, and structural core testing.
Aggregate quality testing for quarries, road projects, and construction. Los Angeles Abrasion, grading, and durability.
In-situ and laboratory pavement testing for roads and highways. FWD deflection, nuclear density, and layer sampling.
Geotechnical investigation and consultancy for commercial, civil, and infrastructure projects. RPEQ signed reports.
Acid Sulfate Soils (ASS) are a serious environmental and structural risk in coastal and low-lying Queensland. Many development sites require ASS assessment as a condition of Development Approval — and getting it wrong can cause irreversible damage and costly remediation.
ASCT provides the full spectrum: sampling, laboratory testing, risk classification, and complete ASS Management Plans that satisfy council and DESI requirements.
Field investigation including borehole drilling, soil sampling, and field screening using hydrogen peroxide tests.
Chromium reducible sulfur (CRS), pH testing, and net acid generation (NAG) testing in our accredited labs.
Formal report classifying actual ASS (AASS) and potential ASS (PASS) risk levels to Queensland state planning requirements.
A full ASS Management Plan detailing treatment, neutralisation, and handling procedures — ready for your DA submission.
ASS testing is required under Queensland's State Planning Policy for any development that involves soil disturbance below 5m AHD, or within designated ASS risk areas identified by council mapping.
Speed, accuracy, and reliability aren't optional extras — they're the baseline your project depends on. We've built our business around delivering exactly that, at every scale.
All testing conducted in our NATA accredited laboratories. Reports accepted by councils, certifiers, and engineers across QLD, NSW, and VIC — first time, every time.
