Australia's largest independently owned Construction Materials Testing company. 30+ years, 15 NATA accredited labs, and a full range of CMT services across the Eastern Seaboard.
Australian Soil & Concrete Testing is the largest independently owned Construction Materials Testing (CMT) company on Australia's Eastern Seaboard.
For over 30 years, ASCT has provided our clients with the confidence to deliver some of Australia's largest infrastructure, development, energy and construction projects. Our network of NATA accredited laboratories extends from the northern reaches of Queensland through New South Wales and into Victoria.
Full-spectrum construction materials testing — from a single residential slab classification to ongoing CMT support for major infrastructure projects.
Comprehensive laboratory and field soil testing. CBR, Proctor compaction, Atterberg limits, shrink-swell, particle size, and moisture content.
Field and laboratory concrete testing including compressive strength, slump, density, air content, and core extraction and testing.
QBCC licensed site classification reports for residential slabs and footings. Council-ready reports for builders, certifiers, and developers across QLD, NSW, and VIC.
Aggregate quality testing for quarries, road construction, and concrete. Los Angeles Abrasion, wet/dry strength, grading, flakiness, and soundness testing.
In-situ and laboratory pavement testing for roads and highways. Nuclear density, DCP, FWD, layer sampling, lime stabilisation, and foamed bitumen.
Geotechnical investigation and consultancy for commercial, civil, and infrastructure projects. RPEQ signed reports for foundation design, earthworks, and retaining structures.
Full NATA testing capability brought to remote sites, large infrastructure corridors, and projects beyond fixed lab range — anywhere on the Eastern Seaboard.
Acid Sulfate Soils (ASS) are a serious environmental and structural risk in coastal and low-lying Queensland. Many development sites require a formal ASS assessment as a condition of Development Approval — and getting it wrong can trigger costly remediation and project delays.
ASCT provides the full ASS scope: site sampling, NATA lab testing, risk classification, and complete ASS Management Plans that satisfy council and DESI requirements.
Borehole drilling and soil sampling with field screening using hydrogen peroxide tests to identify ASS presence.
Chromium reducible sulfur (CRS), pH testing, and net acid generation (NAG) analysis in our accredited labs.
Formal classification of Actual ASS (AASS) and Potential ASS (PASS) risk levels to Queensland state planning requirements.
A complete management plan detailing treatment, neutralisation, and soil handling procedures — DA-submission ready.
Required under Queensland's State Planning Policy for any development involving soil disturbance below 5m AHD, or within ASS risk areas identified by council mapping.
Speed, accuracy, and reliability aren't optional extras in construction — a delayed or rejected report can hold up an entire project. We've built our business around the disciplines that matter most to builders and developers.
From a single residential lot to a 10,000-lot master-planned estate, our capacity and commitment to quality remain the same.
All testing in our NATA accredited labs. Reports accepted by councils, certifiers, and engineers across QLD, NSW, and VIC — first time, every time.
Standard site classification in 2–3 business days. Express next-business-day service available. We publish our times and we meet them.
From initial site classification through to ongoing compaction monitoring and concrete testing — ASCT delivers the full CMT scope on a single account.
Proud to be heavily involved in engagement programs for Aboriginal, Torres Strait Islander, and Mature-Age workers as we grow to be Australia's number one CMT company.
The ASCT client portal gives builders and developers a single dashboard to manage all their testing across every active project. No chasing reports by email.
Multi-phase pavement and geotechnical testing across four upgrade stages — NSW North Coast.
Full geotechnical investigation and CMT for 120-turbine renewable energy facility — foundation design and ongoing testing.
Ongoing CMT partner for 17,000-lot residential development — site classification, concrete, and compaction testing.
Construction materials testing and geotechnical support for major bridge replacement — concrete, aggregate, and soil.
Geotechnical investigation and ongoing monitoring for ash dam management at major QLD power station.
Full construction materials testing scope for major QLD motorway upgrade — pavement, soil, and concrete throughout construction.
