Need an existing concrete floor or structural slab investigated? Magnitude Geo provides targeted GPR concrete floor scanning throughout London, the Home Counties and South East England.
Our surveys can investigate reinforcement within concrete floors before drilling, core drilling, service penetrations, saw cutting, structural alterations and new openings.
Whether you require a small targeted scan or reinforcement mapping across a larger floor area, we can develop a survey approach appropriate to your project.
Send us your drawings, photographs and marked-up survey locations where available. Our team can review the requirements and provide a free, no-obligation quotation.
Why Scan a Concrete Floor?
Reinforced concrete floors can contain multiple layers of reinforcement, conduits and other embedded features that are not visible from the surface.
Concrete floor scanning can provide additional information about the internal reinforcement arrangement before intrusive works commence, helping contractors and engineers assess proposed drilling, cutting and penetration locations.
Targeted scanning around proposed floor penetrations.
Reinforcement investigation before saw cutting and new openings.
Scanning around proposed mechanical and electrical penetrations.
Investigation of existing floors before refurbishment and modifications.
GPR Concrete Floor Scanning
Ground Penetrating Radar is a non-destructive investigation method used to assess reinforced concrete floors and structural slabs.
Radar responses can provide information regarding reinforcement position, direction, approximate spacing and indicative depth within the surveyed floor area.
Depending on the slab construction and survey conditions, GPR may also identify responses from deeper reinforcement layers and other detectable embedded features.
Learn more about our GPR Survey London service.
Rebar Detection in Concrete Floors
Reinforcing steel is one of the principal features investigated during concrete floor scanning.
Where reinforcement responses can be clearly identified, their positions can be marked directly onto the accessible floor surface, providing contractors and engineers with a practical reference for subsequent works.
More detailed investigations can assess reinforcement direction, approximate spacing and indicative depth across selected floor areas.

Concrete Floor Scanning Before Drilling & Coring
Concrete floor scanning is commonly required before drilling, core drilling and forming new penetrations through existing reinforced concrete slabs.
Magnitude Geo can undertake targeted scans around individual drilling locations or survey larger floor areas where multiple penetrations or alterations are proposed.
Detected reinforcement can be marked directly onto the concrete surface where required so that proposed work locations can be compared with the survey findings.
- Core drilling locations
- Diamond drilling
- Service penetrations
- Drainage penetrations
- Mechanical and electrical routes
- New structural openings
Reinforced Concrete Floor Investigation
Concrete floor scanning can also support structural investigations where information regarding the existing reinforcement arrangement is unavailable or requires further verification.
Systematic GPR scanning across selected floor areas can help establish reinforcement direction, approximate spacing and indicative depth for use alongside structural drawings and other available project information.
These investigations can support refurbishment, strengthening, change-of-use and structural alteration projects involving existing reinforced concrete floors.
Concrete Floor & Slab Scanning Applications
Magnitude Geo undertakes floor scanning across a range of commercial, residential and structural environments.
Structural Floor Slabs
Reinforcement mapping before drilling, cutting and structural modifications.
Basement Floors
GPR investigation before service installations, drainage and refurbishment works.
Commercial Floors
Targeted scanning during fit-out, alterations and building-services works.
Existing Concrete Slabs
Investigation of reinforcement where existing structural information is limited.
For wider slab investigations, visit our Concrete Slab Scanning London page.
Scanning Concrete Floors From the Underside
Where the upper floor surface cannot be accessed, it may be possible to investigate the slab from the underside or soffit.
This approach can be useful within basements, commercial buildings and occupied properties where access to the upper surface is restricted.
When scanning from underneath, interpreted depth information is referenced from the soffit surface being scanned.
Survey grids and reinforcement positions can also be marked onto the accessible ceiling surface where required.
Concrete Floor Survey Deliverables
Survey outputs can be tailored to the size of the floor area and the level of information required by the project team.

Concrete Floor Scanning FAQs
Can you scan reinforcement in a concrete floor?
Yes. GPR and reinforcement detection equipment can be used to investigate reinforcing steel within accessible concrete floors.
Can you scan a floor before drilling?
Yes. Targeted concrete floor scanning can be undertaken around proposed drilling, coring and fixing locations.
Can you scan before cutting a concrete floor?
Yes. Survey areas can be established around proposed cutting zones and structural openings before intrusive works commence.
Can GPR identify reinforcement depth?
GPR can provide indicative depth information. Accuracy depends on the concrete properties, survey conditions and dielectric value used for interpretation.
Can you scan from underneath a floor slab?
Yes. Where suitable access is available, scanning can be undertaken from the underside or soffit of the slab.
Can detected reinforcement be marked on the floor?
Yes. Where appropriate, detected reinforcement can be marked directly onto the accessible concrete surface.
Can you provide a concrete floor scanning report?
Yes. Depending on project requirements, Magnitude Geo can provide annotated photographs, processed GPR outputs, reinforcement information and technical survey reports.
