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, GPR surveys 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.

What is concrete imaging?

Concrete imaging is another term used to describe advanced concrete scanning techniques. Using Ground Penetrating Radar (GPR), we can identify reinforcement, rebar, post-tension cables, conduits, voids and embedded services within concrete before drilling, coring or cutting.

Do you provide concrete X-ray services?

Concrete X-ray is a term commonly used to describe concrete scanning. Magnitude Geo uses advanced Ground Penetrating Radar (GPR) technology to locate reinforcement, rebar, post-tension cables, conduits and embedded services within concrete quickly, accurately and without damaging the structure.

What is slab scanning?

Slab scanning uses Ground Penetrating Radar (GPR) to inspect concrete slabs before drilling, coring or cutting. Our surveys accurately identify reinforcement, post-tension cables, conduits, voids and other hidden features to help contractors work safely.

Can you provide rebar mapping?

Yes. Our concrete scanning surveys provide accurate rebar mapping and reinforcement detection, allowing contractors and structural engineers to identify steel reinforcement before structural alterations, drilling or demolition works.

Do you provide GPR scanning services in London?

Yes. Magnitude Geo provides professional GPR scanning services throughout London, the Home Counties and South East England. Our Ground Penetrating Radar surveys support construction, refurbishment and structural investigation projects by accurately locating hidden features within concrete.
