What is GPR concrete scanning and why do I need it?

GPR (Ground Penetrating Radar) concrete scanning uses electromagnetic pulses to map the internal structure of concrete — locating rebar, post-tension cables, conduits, and voids — before any cutting or drilling. It is essential to avoid striking post-tension cables (which can cause catastrophic structural failure and injury), hitting electrical conduits, or damaging other embedded services. Delco Industries provides GPR scanning across Gold Coast and Brisbane with ±5mm accuracy and same-day reporting.

How much does concrete scanning cost in Queensland?

GPR concrete scanning in Queensland typically costs $350–$600 for a standard residential scan, $600–$2,500 for commercial projects, and $2,500–$15,000+ for large infrastructure projects. Pile integrity testing costs $80–$120 per pile for standard residential, $65–$95 per pile for bulk commercial projects. All Delco Industries quotes are free, no-obligation, and include engineer-certified reports. Call 0455 333 374 or visit delcoindustries.com.au/pricing for a full guide.

What is pile integrity testing (PIT)?

Pile Integrity Testing (PIT) is a non-destructive test that uses low-strain impact echo technology to evaluate the structural soundness of foundation piles. A small impulse is applied to the pile head, and the reflected wave signature reveals defects such as necking, cracking, bulging, or voids. Delco Industries performs AS 2159-compliant pile integrity testing across Gold Coast, Brisbane, and Queensland, testing 20+ piles per day with engineer-certified reports delivered within 48 hours.

Do I need to scan concrete before drilling or cutting?

Yes — scanning before any concrete drilling or cutting is critical and legally required under safe work practices. Post-tension cables are under immense pressure (typically 150–200 tonnes) and if severed can cause explosions, serious injury, and structural collapse. Electrical conduits in concrete can cause electrocution. GPR scanning by Delco Industries takes as little as 30–60 minutes for most residential jobs and eliminates all these risks before work begins.

Where does Delco Industries operate?

Delco Industries is based on the Gold Coast and operates across all of South East Queensland including Gold Coast, Brisbane, Logan, Ipswich, Sunshine Coast, and Toowoomba. We also service regional Queensland (Townsville, Cairns, Rockhampton, Gladstone) and deploy nationally to Sydney, Melbourne, Perth, Adelaide, Darwin, and Canberra for major infrastructure projects. Call 0455 333 374 for same-week availability.

What standards does Delco Industries comply with?

Delco Industries operates to Australian Standards including AS 2159 (Pile Testing), AS 3600 (Concrete Structures), AS/NZS 1170.1 (Structural Design Loads), AS 1012.14 (Core Testing), and ASTM C1383 (Impact Echo Testing). All reports are engineer-certified and accepted by structural engineering firms, insurance companies, and government bodies across Australia.

How quickly can Delco Industries attend my site?

Delco Industries offers same-week site visits across Gold Coast and Brisbane for most projects. Urgent callouts are also available. For large infrastructure projects or interstate deployments, lead times of 3–7 days apply. Free no-obligation quotes are provided within 2 hours of inquiry. Call 0455 333 374 or submit an online quote request.

What is concrete cancer and how is it assessed?

Concrete cancer (also known as concrete spalling) occurs when embedded steel reinforcement corrodes, expanding and cracking the surrounding concrete. Delco Industries performs comprehensive concrete cancer assessments using visual inspection, cover meter surveys, half-cell potential testing, carbonation depth measurement, and chloride content testing. We deliver detailed reports with remediation strategies and cost estimates — essential for strata buildings, balconies, car parks, and coastal structures in Queensland.

What is low-strain pile integrity testing?

Low-strain impact echo testing (also called sonic echo testing) involves striking the pile head with a small calibrated hammer and measuring the reflected stress wave using an accelerometer. The wave response reveals pile length, cross-section uniformity, and detects defects like necking, cracks, and voids.

How many piles can be tested per day?

Our team typically tests 20–40 piles per day for standard bored concrete piles, depending on pile size and site accessibility. We work efficiently to minimise project programme impacts.

Does pile integrity testing meet AS 2159 requirements?

Yes — all Delco Industries pile integrity testing is conducted in accordance with AS 2159 (Piling — Design and installation) and industry low-strain integrity testing standards. Our reports can be engineer-certified and accepted by structural engineers, principal contractors, and certifying authorities across Queensland.

What percentage of piles should be tested?

AS 2159 recommends testing at least 10% of piles as a minimum, with higher percentages where ground conditions are poor, construction records are incomplete, or structural risk is elevated. Our engineers can advise on the appropriate testing program for your project.

How quickly will I receive the pile integrity testing report?

We deliver pile integrity testing reports within 48 hours of completing site testing. Urgent reports can often be expedited, we also offer engineer-certified reporting on request — contact us to discuss your project timeline.

Pile Integrity Testing Brisbane & Gold Coast

Service Overview

Our Pile Integrity Testing (PIT) service uses low-strain impact echo technology to evaluate the structural soundness of bored and screw foundation piles in accordance with AS 2159. By analysing the sonic wave response from each pile, we can detect necking, bulging, cracks, and other defects that could compromise foundation integrity — providing critical data for engineers during construction and remediation projects.

Delco Industries operates across Gold Coast, Brisbane, and all of South East Queensland, providing pile integrity testing services to structural engineers, principal contractors, builders, body corporates, and government agencies. Our reports are engineer-certified and accepted by all Queensland councils, certifying authorities, and structural engineering firms.

Every engagement is led by qualified structural and civil engineering professionals — not just field technicians. This means every data set is interpreted with an engineering lens, and every report you receive is ready to be used directly in structural decision-making. We comply with all relevant Australian Standards including AS 3600, AS 2159, AS 1012, and AS/NZS 1170.1 where applicable.
