Need a reinforced concrete wall scanned in London? Magnitude Geo provides targeted GPR wall scanning for contractors, structural engineers, developers and construction professionals.
Our surveys can support drilling, coring, wall openings, structural alterations, fit-out works and reinforcement investigations where information about the existing concrete wall is required.
Send us photographs, drawings and marked-up wall locations where available. For proposed openings or penetrations, include the approximate size and position of the works if known.
Our team can review the information and provide a free, no-obligation quotation.
Why Scan a Concrete Wall?
Reinforced concrete walls can contain vertical and horizontal reinforcement, multiple layers of steel and other embedded features that are not visible from the finished wall surface.
Concrete wall scanning provides non-destructive information about the selected survey area before intrusive works begin and can help project teams better understand the structure around proposed drilling, cutting or opening locations.
Reinforcement investigation around proposed doorways, service openings and structural penetrations.
Targeted scanning around proposed drilling, anchor and fixing positions.
Investigation of existing reinforced concrete walls before modification.
Representative reinforcement information for structural assessment and refurbishment projects.
GPR Concrete Wall Scanning
Ground Penetrating Radar is a non-destructive method used to investigate reinforced concrete from an accessible surface.
Radar data can be collected across controlled survey grids positioned on the wall. Reflections within the data are interpreted to investigate reinforcement and other detectable features within the selected area.
Where survey conditions permit, GPR can provide information regarding reinforcement position, direction, approximate spacing and indicative depth from the scanned surface.

Rebar Detection in Concrete Walls
Reinforcing steel within concrete walls is commonly arranged vertically and horizontally, with reinforcement layouts varying according to the structural design.
Where reinforcement responses can be clearly interpreted, their positions can be mapped within the surveyed area and marked directly onto the wall surface where required.
This information can assist structural engineers and contractors when reviewing proposed penetrations, wall openings, new fixings and structural alterations.

Scanning Before Cutting Openings in Concrete Walls
Proposed openings through reinforced concrete walls may intersect reinforcement or other embedded features within the structure.
Magnitude Geo can undertake GPR scanning across and around the proposed opening to provide additional information about the reinforcement arrangement before cutting or breakout works commence.
Typical applications include:
- Door openings
- Service penetrations
- Duct openings
- Mechanical and electrical routes
- Structural alterations
- New access openings
- Core drilling
- Diamond cutting
Concrete Wall Scanning Before Drilling & Fixings
Concrete wall scanning can also be undertaken around smaller proposed drilling and fixing locations.
This may include structural connections, resin anchors, mechanical fixings, brackets, building services and other installations where drilling into reinforced concrete is required.
Survey coverage can be concentrated around individual fixing zones or extended across larger wall areas containing multiple proposed drilling locations.
Where required, interpreted reinforcement positions can be marked directly onto the accessible wall surface.
Reinforced Concrete Walls We Can Investigate
Magnitude Geo can undertake wall scanning across a range of accessible reinforced concrete structures depending on the project requirements and site conditions.
Structural Walls
Reinforcement investigation before alterations, penetrations and structural works.
Basement Walls
Scanning of accessible basement wall areas for refurbishment and structural investigation projects.
Shear Walls
Targeted reinforcement investigations where information regarding existing wall construction is required.
Retaining Walls
Representative scanning of accessible concrete surfaces subject to project conditions and survey requirements.
Concrete Wall Reinforcement Surveys for Structural Engineers
Structural engineers may require reinforcement information within existing concrete walls before refurbishment, redevelopment, change of use or proposed structural alterations.
Magnitude Geo can undertake representative GPR survey grids across engineer-specified locations to investigate reinforcement arrangement, direction, approximate spacing and indicative depth.
Available structural drawings, marked-up investigation locations and other project information can be reviewed alongside the site findings.
For wider reinforcement investigations, visit our Reinforcement Survey London service.
Scanning from One or Both Sides of a Concrete Wall
Many concrete wall surveys can be undertaken from one accessible face of the structure.
Where both sides of the wall are accessible and the project requires a more detailed investigation, survey data may be collected from both faces to provide additional information about the reinforcement arrangement.
The most appropriate survey approach depends on wall thickness, reinforcement congestion, access, surface condition and the information required by the project team.
Concrete Wall Scanning Survey Deliverables
Survey outputs can be tailored to the project. Small targeted scans may require physical mark-ups and photographs, while engineering investigations can require processed information and formal reporting.

Concrete Wall Scanning FAQs
What is concrete wall scanning?
Concrete wall scanning is a non-destructive survey used to investigate reinforcement and other detectable embedded features within an accessible reinforced concrete wall.
Can GPR locate rebar in concrete walls?
Yes. GPR can be used to investigate reinforcement position, direction and approximate spacing within reinforced concrete walls where survey conditions permit.
Can you scan a wall before cutting an opening?
Yes. GPR survey grids can be positioned across and around a proposed wall opening to investigate the reinforcement arrangement before intrusive works commence.
Can you scan before drilling into a concrete wall?
Yes. Targeted surveys can be undertaken around proposed drilling, core, anchor and fixing locations.
Can you determine rebar depth in a wall?
Indicative depth information may be obtained where the radar data, concrete conditions and reinforcement arrangement allow reliable interpretation.
Can you scan both sides of a concrete wall?
Yes. Where both wall faces are accessible, scanning can be undertaken from both sides if this is beneficial to the required investigation.
Can detected reinforcement be marked on the wall?
Yes. Where appropriate, interpreted reinforcement positions can be marked directly onto the accessible concrete surface.
Do you provide concrete wall scanning reports?
Yes. Depending on the agreed scope, Magnitude Geo can provide annotated photographs, processed GPR information, technical reports and CAD or PDF drawings.
How much does concrete wall scanning cost?
The cost depends on the number and size of survey areas, wall access, project location, structural complexity and reporting requirements. Send us drawings or photographs for a project-specific quotation.
