Non-Destructive Structural Investigation
HCS has the ability to test structures using non-destructive technologies including Schmidt Hammer testing. This provides clients with an alternative to destructive methods of assessing structural integrity, producing immediate insights into the strength of the concrete structure. We give structural engineers, building contractors, forensic experts and concrete specialists the essential information they require, and service multi-national companies, engineering and construction specialists, local and state government bodies, as well as residential and small business clients.
Structural investigation is a cost-effective way to assess a structure's condition without the delay or disruption of destructive testing. Our technicians combine Schmidt Hammer testing with the same GPR concrete scanning technology used in our concrete scanning services to build a complete picture of reinforcement, strength and condition, whether you're assessing an ageing structure, verifying compliance, or investigating damage.
Much of the information produced by our technicians is acquired in real time, we are often able to provide on the spot MPA values for the structural elements being investigated.
Structural Investigation Applications
- Non-destructive testing of concrete and structural components.
- Relative concrete strength and quality
- Bridge Deck Analysis
- Quality Assurance Reporting
- Facade and building condition assessments
- Pre-purchase and insurance structural assessments
Structural Investigation Experience
HCS has significant structural investigation experience across infrastructure, commercial and residential projects. Our technicians have been engaged for facade investigations, bridge deck analysis and structural integrity assessments across Melbourne, Newcastle and Brisbane. This work often complements our underground service locating services on the same site, and you can learn more about our qualifications and industry associations on our About page.

What Affects Schmidt Hammer Reading Accuracy
Schmidt Hammer results are only as reliable as the surface and technique behind them. Surface texture, carbonation, moisture content, and the angle and consistency of each impact all influence the rebound value – which is why HCS takes multiple readings per test area and averages them rather than relying on a single strike. Results are indicative of relative concrete strength rather than a certified compressive strength figure; where a project needs certified data for compliance sign-off, HCS can arrange core extraction and NATA-accredited lab testing alongside the Schmidt Hammer survey.
Frequently Asked Questions
What is structural investigation and when do I need it?
Structural investigation assesses the condition, strength and integrity of concrete and structural elements using non-destructive testing methods like Schmidt Hammer testing. It's used to evaluate ageing structures, verify load capacity, investigate damage, or support pre-purchase and insurance assessments.
What is Schmidt Hammer testing?
Schmidt Hammer testing is a non-destructive method that measures the surface hardness of concrete to estimate its compressive strength (MPA value). It provides immediate, on-the-spot results without damaging the structure being tested.
Is structural investigation non-destructive?
Yes. Our structural investigation methods, including Schmidt Hammer testing, assess structural integrity without drilling, coring or otherwise damaging the structure, making them a cost-effective alternative to destructive testing.
What areas do you service?
HCS provides structural investigation services across Melbourne and Victoria, with additional offices in Newcastle, NSW and Brisbane, QLD.
What structures can be tested?
We test a wide range of structures including bridge decks, building facades, slabs, columns and other concrete and structural elements across commercial, infrastructure and residential projects.
How long does a structural investigation take?
Most structural investigations are completed on site with results available in real time. Project duration depends on the size and complexity of the structure, and we'll provide a clear timeframe before work begins.
Are your technicians qualified and insured?
Yes. Our structural investigation technicians are experienced and qualified, and HCS carries professional indemnity, public liability and workers compensation insurance for your peace of mind.
How do I book a structural investigation?
Call 1300 859 027 or submit an enquiry through the form below, and the team will confirm scope and scheduling for your site
How much does a structural investigation cost?
Cost depends on the size of the structure, number of test locations, and whether follow-up core testing is required. Call 1300 859 027 or submit an enquiry and the team will scope a quote for your project.
How is Schmidt Hammer testing different from core testing?
Schmidt Hammer testing is non-destructive and gives an immediate, indicative read of relative concrete strength on site. Core testing physically extracts a sample for NATA-accredited lab testing, giving a certified compressive strength figure but taking longer and requiring a small amount of drilling. Many projects use Schmidt Hammer testing first and escalate to core testing only where certified data is required.
How many test points does a structural investigation need?
This depends on the size and condition of the structure and what the assessment is for. HCS scopes the number of test locations with you before the job starts, based on the specific structure and purpose of the assessment.
