GPR Concrete Scanning, Concrete Radar & Slab Scanning

No. GPR is not X-ray. Ground Penetrating Radar uses low-power electromagnetic radio waves and receives reflected signals to map subsurface features from one accessible surface. It does not use ionising radiation, does not require radiation exclusion zones, and is generally suitable for occupied environments. X-ray (radiography) is a different method that uses ionising radiation and stricter safety controls.

A standard package includes site capture methodology, marked-up plans, identified reinforcement and post-tension risk zones, mapped service corridors where detectable, confidence zoning, and recommended verification hold points. For projects requiring model-based coordination, SiteOps can also provide CAD/BIM-ready overlays and data extracts aligned to the project grid and level set-out.

Yes. If the slab may contain reinforcement, post-tension tendons, conduits, or embedded services, GPR scanning should be completed before any core, saw-cut, anchor, or penetration work. SiteOps marks likely risk zones and provides notes on scan confidence so the engineer and site team can choose safer penetration locations and decide where extra verification is needed.

Yes. SiteOps regularly scans post-tension slabs in Brisbane commercial, residential, and mixed-use buildings. GPR is used to identify likely tendon alignments, reinforcement zones, and slab features before fit-out works, anchor installation, or structural changes. Results are issued as practical markups and report notes for consultant and contractor review.

Yes, by scheduled deployment. SiteOps supports Gympie and northern Sunshine Coast projects where concrete x-ray alternatives, slab scanning, GPR, rebar mapping or pre-core checks are needed. We usually plan these visits with a defined test list so the mobilisation is efficient and the report answers the contractor or engineer question.

Yes. As-built detailing is specifically designed for that situation. We establish a measured baseline directly from site conditions, then highlight discrepancies between observed conditions and any available legacy documentation. This allows design and construction teams to make decisions on current reality instead of assumptions.

Accuracy depends on access, element type, and capture method; accordingly, SiteOps reports confidence by zone rather than claiming a single blanket tolerance. High-confidence zones can be used for immediate coordination, while medium-confidence areas are flagged for controlled verification prior to irreversible works such as drilling, cutting, or fixing.

The highest value is early - during concept or developed design, before procurement and definitely before site cutting starts. Early as-built capture reduces redesign cycles, prevents latent-condition surprises, and allows contractors to plan methodology and sequencing with fewer variations during delivery.
