Rebar Survey Services
Locate reinforcing steel before you drill or cut. Non-destructive GPR rebar scanning gives your team exact positions and depths, on-site, often the same day.

What Is a Rebar Survey?
See where the steel is before you cut the slab
A rebar survey – also known as GPR scanning or rebar detection – is a non-destructive testing (NDT) method that uses radar pulses to detect and map reinforcing steel embedded within concrete structures. It gives engineers, contractors and project managers accurate data on the exact position and depth of rebar before core drilling commences.
Essential for
- Core drilling and concrete cutting projects
- Pre-construction slab inspections
- Structural assessments and load-bearing evaluations
- Determining safe drill point locations in reinforced concrete
- Renovation and retrofitting projects on existing structures
- Any project where rebar location and depth must be confirmed before penetration

Why Rebar Surveys Matter
Eliminate the guesswork before the first hole
Striking reinforcing steel during a core drilling job damages your diamond bit, can compromise the structural integrity of the concrete element, and creates costly rework. A rebar survey eliminates the guesswork – telling your operator exactly where the steel is and how deep, so drill points can be positioned safely and precisely.
At Vus Core Drilling, we recommend every core drilling job begins with a rebar survey. Our GPR surveys are fast, non-invasive, and deliver results on-site so your team can proceed with confidence – the same principle applies before stitch core drilling, floor sawing or controlled demolition on structural elements.
Frequently Asked Questions
Rebar surveys, answered
What is a rebar survey?
A non-destructive method using radar pulses (GPR) to detect and map reinforcing steel inside concrete, giving exact position and depth before drilling.
Why do I need a rebar survey before core drilling?
Striking rebar damages your bit, can compromise structural integrity, and creates costly rework. A survey removes the guesswork.
How fast is a rebar survey?
Fast and non-invasive, with results delivered on-site – same-day options are available.
What does a rebar survey include?
GPR scanning, rebar location/depth/spacing mapping, on-site marking, a detailed survey report, and coverage across Gauteng and national sites.
