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.

Do you scan before cutting?

Always. Every cut location requires to be GPR-scanned before any coring / cutting works begin. This is non-negotiable — it protects post-tension cables, rebar, and embedded services.

What's the maximum cutting depth?

Our wall saws cut up to 300mm deep. For thicker elements, we use stitching techniques (overlapping cuts). Floor saws handle depths up to 500mm. Most residential and commercial slabs and walls fall well within these capacities.

Can you cut post-tension concrete slabs?

Yes — but only after comprehensive GPR scanning to map all PT cable positions. We never cut a PT slab without a full scan. Our team has extensive experience safely cutting post-tension structures and can advise on the safest cut routing.

Concrete Cutting Brisbane & Gold Coast

Service Overview

Our precision concrete cutting services utilise industrial-grade diamond blade technology to deliver clean, accurate cuts in floors, walls, and structural concrete elements. Combined with our GPR scanning capabilities, every cut is informed by subsurface data—eliminating the risk of hitting rebar, post-tension cables, or embedded services and ensuring structural integrity is maintained.

Delco Industries operates across Gold Coast, Brisbane, and all of South East Queensland, providing concrete cutting 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.
