At Concrete Scanning, we specialise in non-invasive sub-surface imaging to locate hidden objects within concrete before any drilling, coring, or cutting takes place.

Using advanced scanning technology, we detect rebar, conduits, post-tension cables, voids, and other embedded hazards, helping construction professionals avoid costly mistakes, delays, and safety risks.

Whether you’re working on a high-rise, hospital, or infrastructure site across the UK, our precision scanning supports smarter, safer decisions on every project.

Why Is Concrete Scanning Essential Before Drilling Or Coring?

Concrete scanning protects workers, structural integrity, and critical services before invasive work.

By identifying what’s hidden beneath the surface, we help avoid striking rebar, live electrical conduits, or post-tension cables, which can result in structural failure, safety risks, or service outages.

Concrete scanning also reduces the need for trial-and-error coring, saving time and money while ensuring compliance with project requirements and health and safety regulations.

How Much Does Concrete Scanning Cost?

Costs for concrete scanning start around £250, while complex or multi-zone scans with CAD drawings and reports range from £500 to £1,500+.

Pricing also varies with site access, number of scan locations, and reporting needs such as 3D modelling or slab thickness analysis.

What Can Be Detected With Concrete Scanning Technology?

Concrete scanning technology identifies various embedded components and structural characteristics, including:

• Rebar for structural reinforcement mapping – Accurately locate steel reinforcement to avoid accidental damage.
• Mesh embedded in slab systems – Detect wire mesh used in concrete slabs and walls.
• Post-tension cables under high stress – Identify and trace critical tendons to maintain structural safety.
• Electrical conduits for service layout – Locate metal or plastic conduits to prevent electrical service disruption.
• Water pipes and plumbing lines – Detect active or dormant piping within or beneath concrete surfaces.
• Slab voids and hidden cavities – Identify air pockets or unfilled zones that compromise strength.
• Cracks and internal fractures – Detect subsurface cracking that may affect load-bearing capacity.
• Steel beams embedded in concrete – Locate structural steel elements within composite systems.
• Slab depth and concrete cover measurements – Assess thickness and rebar protection for compliance and planning.

What Technology Is Used In Concrete Scanning?

Concrete scanning requires Ground Penetrating Radar (GPR), electromagnetic sensors, and cover metres to scan through concrete surfaces.

GPR sends radar pulses into the concrete and measures their reflection to map embedded objects.

Cover metres and EM scanners provide additional data on metal depth, spacing, and type. Each tool is selected based on the material, required depth of scan, and level of detail needed.

What Types Of Structures Require Concrete Scanning Services?

Concrete scanning is used on slabs, walls, ceilings, beams, columns, and decks in all types of construction.

We work on residential towers, commercial developments, industrial plants, hospitals, tunnels, car parks, and bridges.

Whether the project is a new build, retrofit, or demolition, scanning helps guide safe, accurate structural modifications.

What Are The Deliverables From A Concrete Scan?

Our concrete scanning services provide real-time on-site markings and digital documentation to support safe construction decisions.

Depending on your requirements, deliverables may include 2D and 3D digital scans, CAD-based drawings, depth reports, object location grids, and photographic evidence.

Our findings are clearly annotated and easy to interpret, giving site teams and designers the confidence to proceed.

Who Uses Concrete Scanning Services?

Concrete scanning services are for the following professionals:

• General contractors managing construction risk – Use scanning to avoid striking embedded elements during site works.
• Engineers conducting structural analysis – Gain precise data on reinforcement and concrete conditions.
• Architects planning refurbishments or retrofits – Assess existing structures for safe design adaptations.
• Building owners maintaining structural assets – Monitor sub-surface conditions for ongoing maintenance and upgrades.
• M&E contractors installing building services – Scan for safe locations to route pipes, conduits, and ducts.
• Demolition firms preparing structural removals – Identify critical reinforcements before cutting or breaking.
• Specialist trades involved in coring or anchoring – Ensure clear zones for precise drilling and fixing.

How Long Does A Typical Concrete Scanning Job Take?

A small concrete scan covering a few square metres might take under an hour, while large floor slabs or multi-surface projects could take a full day or more.

If full reports and CAD drawings are required, reporting may take an additional 24–48 hours depending on complexity.
