GPR Survey London
Magnitude Geo provides professional GPR survey and concrete scanning services across London using advanced Ground Penetrating Radar (GPR) technology
Our GPR surveys help locate rebar, reinforcement, post-tension cables, conduits, voids and embedded services within concrete. We also provide rebar detection surveys and drawings to support structural engineers, contractors and project teams before drilling, coring or cutting works begin.
Ground Penetrating Radar is a non-destructive scanning method used to identify hidden objects and structural features without damaging the concrete. It is ideal for safe construction planning, structural investigations, and pre-drilling surveys across London.
Rebar Detection London
Magnitude Geo uses advanced GPR technology to locate reinforcement and rebar within concrete slabs, walls and structural elements. Accurate rebar detection helps prevent costly damage during drilling, coring and cutting operations while providing contractors and engineers with confidence before work begins.
Post-Tension Cable Detection London
Post-tension cables can present significant risks if struck during construction works. Our concrete scanning surveys accurately identify post-tension cables before drilling, cutting or demolition activities, helping contractors work safely and avoid structural damage.

Frequently Asked Questions
What is concrete scanning?
Concrete scanning is a non-destructive surveying method used to identify hidden objects and structural elements within concrete before drilling, coring, cutting or refurbishment works. Using Ground Penetrating Radar (GPR), surveyors can accurately locate reinforcement, post-tension cables, conduits, voids and embedded services without damaging the structure.
What can a GPR survey detect?
A GPR survey can detect rebar, reinforcement mesh, post-tension cables, conduits, embedded services, voids and other hidden features within concrete. Ground Penetrating Radar provides accurate information that helps contractors and engineers plan work safely and avoid costly damage.
Can concrete scanning and Ferroscan surveys locate rebar?
Can concrete scanning and Ferroscan surveys locate rebar?
Yes. Concrete scanning is one of the most effective methods for locating rebar and reinforcement within concrete slabs, walls, columns and structural elements. Identifying rebar before drilling or cutting helps prevent structural damage and ensures safe construction practices.
Do I need concrete scanning before drilling?
Concrete scanning is strongly recommended before drilling, coring or cutting concrete. Hidden reinforcement, post-tension cables and embedded services can present serious safety risks if struck. A professional concrete scan helps reduce risk, prevent delays and avoid expensive repairs.
How much does concrete scanning cost in London?
The cost of concrete scanning depends on the size of the area being surveyed, site conditions and project requirements. Magnitude Geo provides competitive pricing for concrete scanning and GPR survey services throughout London. Contact us for a free quotation tailored to your project.
What is Ground Penetrating Radar (GPR)?
Ground Penetrating Radar (GPR) is an advanced non-destructive scanning technology that uses electromagnetic signals to detect and map hidden features within concrete and below the surface.
Can GPR detect post-tension cables?
Yes. GPR technology is commonly used to locate post-tension cables within concrete slabs and structures. Identifying post-tension cables before drilling or cutting is essential to avoid structural damage and ensure safe construction practices.
What is a Ferroscan survey?
A Ferroscan survey is used to locate reinforcement and rebar within concrete structures. Ferroscan technology can be used alongside Ground Penetrating Radar (GPR) surveys to identify steel reinforcement before drilling, coring or cutting concrete, helping improve safety and reduce the risk of costly damage.
Do you provide concrete scanning services throughout London?
Yes. Magnitude Geo provides professional concrete scanning, slab scanning, rebar detection and GPR survey services across Greater London, Central London, the Home Counties and South East England.
