Concrete Slab Scanning London
GPR Concrete Slab Scanning, Rebar Detection & Reinforcement Mapping Across London
Magnitude Geo provides professional concrete slab scanning services throughout London, the Home Counties and South East England. Using specialist Ground Penetrating Radar (GPR) and reinforcement scanning technology, we investigate reinforced concrete slabs to identify rebar, reinforcement patterns and other embedded features before drilling, coring, cutting and structural alterations.
Our surveys can be undertaken from the top surface of a concrete slab or, where access permits, from the underside or soffit. This allows contractors, structural engineers and developers to obtain practical information about the internal construction of existing concrete slabs before intrusive works commence.
Whether you require a small targeted slab scan or a larger reinforcement investigation, Magnitude Geo can provide on-site mark-ups, survey photographs, GPR data, technical reports and CAD deliverables where required.

Professional Concrete Slab Scanning in London
Concrete slabs can contain several layers of reinforcement together with conduits, services, post-tensioning systems and other embedded features. Understanding what is present before intrusive works begin can reduce the risk of damaging important structural reinforcement or concealed elements.
Magnitude Geo undertakes targeted concrete slab surveys using specialist non-destructive scanning equipment. Survey areas can be focused directly around proposed drilling, coring, fixing, cutting or structural alteration locations.

Concrete Slab Scanning Before Drilling & Coring
Drilling or coring into an existing reinforced concrete slab without understanding the internal reinforcement arrangement can create unnecessary risk.
Magnitude Geo provides targeted slab scanning around proposed drilling and coring positions to help identify reinforcement and other detectable embedded features before intrusive work takes place.
Detected reinforcement can be marked directly onto the accessible concrete surface, allowing contractors to consider suitable drilling or coring positions before work begins.
For projects requiring dedicated reinforcement investigation, visit our Rebar Detection London service.
Reinforcement Mapping Within Concrete Slabs
Concrete slab scanning can provide useful information regarding the arrangement of reinforcement within an existing structure.
By scanning systematically across selected areas, repeating reinforcement responses can be identified and used to assess reinforcement direction, approximate spacing and indicative depth.
This information is particularly useful where original structural drawings are unavailable, incomplete or where additional verification of the existing slab construction is required.
Magnitude Geo can provide representative reinforcement mapping for structural engineers investigating existing slabs before refurbishment, extensions, new openings, strengthening works and other structural alterations.
For more detailed structural reinforcement investigations, visit our Reinforcement Survey London page.
Magnitude Geo undertakes reinforcement surveys of reinforced concrete slabs, walls, beams, columns, soffits and accessible foundations throughout London and the Home Counties.GPR Concrete Slab Scanning
Ground Penetrating Radar is widely used for non-destructive investigation of reinforced concrete structures. Radar signals are transmitted into the slab and reflections from reinforcement and other changes within the concrete are recorded and interpreted.
GPR can be particularly useful where information is required beyond the first visible reinforcement layer. Depending on the slab construction and survey conditions, responses may be obtained from multiple reinforcement layers and other embedded features.
Survey results can be reviewed during the site investigation and processed further where technical reporting or more detailed interpretation is required.
Learn more about our dedicated GPR Survey London service.
Concrete Soffit & Underside Slab Scanning
Where the upper surface of a concrete slab is inaccessible, covered or occupied, it may be possible to undertake the survey from the underside of the slab.
Magnitude Geo can scan accessible concrete soffits and ceilings to investigate reinforcement from below. Depth measurements are referenced from the surface being scanned, allowing reinforcement positions to be interpreted relative to the underside of the slab.
This method can be useful in basements, commercial buildings, car parks and refurbishment projects where investigation is required without disturbing the floor finishes above.
Ferroscan & GPR for Concrete Slab Surveys
Different concrete investigations can require different scanning technologies. Ferroscan equipment is particularly useful for locating ferrous reinforcement and assessing reinforcement arrangement close to the concrete surface.
Ground Penetrating Radar can provide additional information through a greater investigated depth and may respond to a wider range of embedded features.
Magnitude Geo can select the appropriate survey method based on the slab construction, access conditions and information required by the client or structural engineer.
Visit our Ferroscan Surveys London page for further information.
Slab Scanning Before Structural Alterations
Concrete slab surveys are frequently required before modifications to existing reinforced concrete structures.
Typical applications include new floor openings, service penetrations, stair openings, structural connections, strengthening works, drilling, resin anchors, saw cutting and refurbishment projects.
The survey can be focused around the proposed alteration area so that the structural engineer and contractor have additional information regarding the existing reinforcement arrangement before work begins.
Concrete Slab Survey Deliverables
The level of survey documentation can be tailored to the requirements of each project.
For smaller targeted slab scans, findings may be marked directly onto the concrete surface and supported by site photographs. Larger or more detailed investigations can include processed GPR information, reinforcement mapping, technical reports and CAD drawings.
- On-site reinforcement mark-ups
- Annotated photographs
- Reinforcement depth information
- Recorded reinforcement spacing and direction
- Processed GPR survey outputs
- Technical survey reports
- CAD and PDF drawings where required

Concrete Slab Scanning FAQs
What is concrete slab scanning?
Concrete slab scanning is a non-destructive investigation used to identify reinforcement and other detectable embedded features within an existing concrete slab.
Can you locate rebar inside a concrete slab?
Yes. Magnitude Geo uses specialist GPR and reinforcement scanning equipment to investigate reinforcing steel within concrete slabs.
Can you scan a slab before drilling?
Yes. Targeted concrete scanning can be undertaken around proposed drilling, fixing or coring positions before intrusive works commence.
Can you scan the underside of a concrete slab?
Yes. Where there is suitable access, concrete slabs can be scanned from the soffit or underside. Reported depths are then referenced from the underside surface being scanned.
Can GPR identify reinforcement depth?
GPR can provide indicative reinforcement depth information. Accuracy depends on the electromagnetic properties of the concrete, the dielectric value used during processing and site conditions.
Can you determine rebar diameter?
Rebar diameter cannot always be reliably confirmed using GPR alone. Where exact reinforcement diameter is critical, additional investigation may be required.
Can you provide a report after the survey?
Yes. Magnitude Geo can provide annotated photographs, processed GPR outputs, reinforcement information, technical reports and CAD drawings depending on the project requirements.
How much does concrete slab scanning cost?
Survey cost depends on the number and size of areas, site access, project location and the level of reporting required. Contact Magnitude Geo for a free project-specific quotation.
Concrete Floor, Ceiling & Soffit Scanning London
Magnitude Geo provides concrete scanning for reinforced concrete floors, structural slabs, ceilings and soffits throughout London. Surveys can be undertaken from the top surface of a slab or, where suitable access is available, from the underside of the concrete structure.
Our concrete slab surveys are used before core drilling, diamond drilling, saw cutting, service penetrations, resin anchors, structural openings and refurbishment works where the position of reinforcement and other detectable embedded features needs to be investigated before intrusive works begin.
Concrete Floor Scanning Before Drilling
Where drilling or coring is proposed through an existing concrete floor, targeted GPR scanning can be carried out around the proposed penetration locations. The survey can help identify reinforcement patterns and other detectable embedded features within the scanned area before drilling begins.
Concrete Ceiling & Soffit Scanning
Concrete slabs can also be investigated from below where the soffit or ceiling surface is accessible. This can be particularly useful within basements, commercial buildings, car parks and refurbishment projects where access to the upper surface of the slab is restricted.
Reinforced Concrete Slab Investigation
For structural investigations, GPR and reinforcement scanning can be used to build a clearer understanding of existing slab construction. Surveys can investigate reinforcement direction, approximate spacing and indicative depth across selected areas of reinforced concrete.
Concrete slab scanning can support structural engineers, contractors and developers working on refurbishment, change-of-use, structural alterations, new openings and modifications to existing reinforced concrete structures.
