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.

GPR Concrete Scanning — Know What's Inside Before You Drill

One unscanned slab can end a project. Delco's GPR concrete scanning locates rebar, post-tension cables, conduits, and voids with millimetre accuracy — so your drill crew can work confidently, quickly, and safely.

Without a GPR scan, you risk:

Severing a live post-tension cable — causing catastrophic structural failure
Cutting through high-voltage electrical conduits — electrocution risk
Damaging pressurised water or gas lines — emergency site shutdown
Triggering slab collapse — project delays worth tens of thousands

What's Included in Every GPR Scan

GPR scan of your entire work zone
On-site rebar, conduit & post-tension cable marking
Same-day digital report with depth data
Engineer-signed clearance certificate

What Brisbane & Gold Coast Builders Say

"Delco had our entire slab scanned and marked by 9am. Drill crew was in by lunch. Zero issues. Will always use them."

James R. · Site Manager — Brisbane CBD

"The report quality is exceptional. Engineer-certified with depth data I can trust and hand straight to my client."

Sarah M. · Structural Engineer — Gold Coast

"Two hours from call to being on site. That kind of response time is unheard of in this industry."
