FAQs
What is concrete scanning and why is it important?
Concrete scanning is the process of using advanced radar technology to locate reinforcement, post-tension cables, conduits, and other objects within concrete. It is important because it prevents costly damage, improves safety, and ensures drilling or cutting can be done with confidence.
How does concrete scanning work?
We use ground penetrating radar (GPR) technology to send signals into the concrete slab. These signals bounce back from objects like rebar or conduits, allowing us to create a clear image of what’s inside before any work begins.
What types of objects can be detected?
Concrete scanning can detect steel reinforcement, post-tension cables, conduits, pipes, and even voids within the slab. This helps reduce the risk during drilling, coring, or cutting.
Do you service all areas of Sydney and NSW?
Yes. ConcreteX provides concrete scanning and investigation services across Sydney and throughout NSW. We regularly attend sites in the CBD, suburbs, and regional areas.
How much does concrete scanning cost?
Pricing depends on site location, the size of the areas, and reporting requirements. As a guide, scans are typically charged by the hour, with day rates available for larger projects. Contact us for a tailored quote.
Can scanning be done on walls, soffits/ceilings, and slabs?
Yes. Our scanners work on horizontal slabs, vertical walls, and overhead soffits/ceilings. We can locate reinforcement and conduits in a wide range of structures.
Is concrete scanning safe for workers and the structure?
Absolutely. The scanning process is non-destructive, meaning it causes no damage to the structure. It also improves site safety by preventing accidental hits on reinforcement, live conduits, or PT cables.
What technology or equipment do you use?
We use the IDS C-Thrue ground penetrating radar system, one of the most advanced concrete scanning tools available. It provides accurate results in real time, even in challenging conditions. We also use other tools to assist us such as Hilti PX10 Transpointers.
Do you provide reports after scanning?
Yes. We deliver clear, image-rich PDF reports that show exactly what was found during the scan. Reports can be provided same day or within 24–48 hours depending on project requirements.
What is anchor pull-out testing?
Anchor pull-out testing measures the strength and reliability of installed fixings in concrete. This ensures anchors meet required load capacities and provides confidence for safety and compliance.
What is concrete strength testing and when is it needed?
Concrete strength testing determines the compressive strength of a slab or structure. It is often required for structural assessments, refurbishments, or when documentation on the original concrete mix is missing.
Do you offer testing for existing buildings or only new projects?
We provide investigation and testing for both new construction and existing buildings. Whether it’s a major infrastructure project or a small commercial fit-out, we can assist.
Do you work with electricians, plumbers, and builders?
Yes. Our services are commonly used by electricians, plumbers, builders, engineers, and asset managers who need safe drilling, coring, or fixing in concrete.
Do you have insurance and qualifications?
Yes. ConcreteX is fully insured with public liability and professional indemnity, ensuring both safety and professional expertise on every project. Our scanning technicians also have nationally recognised training (VU23068 - Scan Concrete) and have all the permits to work on any site in NSW.
