What is Rebar Detection?
Rebar detection is the process of locating steel reinforcement hidden within concrete structures before drilling, coring, cutting or demolition works. Using advanced Ground Penetrating Radar (GPR) and Ferroscan technology, surveyors can accurately identify the position and approximate depth of reinforcing steel without damaging the concrete.
Professional rebar detection surveys help contractors, structural engineers and property professionals understand what lies beneath the concrete surface before work begins. By locating reinforcement, post-tension cables, conduits and embedded services, construction teams can plan works safely while reducing the risk of striking critical structural elements.
Magnitude Geo provides professional rebar detection services throughout London, the Home Counties and South East England, delivering accurate on-site mark-ups, detailed survey reports and rebar mapping to support safe construction, refurbishment and structural alteration projects.
Why is Rebar Detection Important?
Accurate rebar detection is essential before drilling, coring, cutting or carrying out structural alterations to concrete. Reinforcing steel forms part of a building's structural integrity, and accidentally striking rebar or post-tension cables can lead to costly repairs, project delays and serious safety risks.
Using advanced Ground Penetrating Radar (GPR) and Ferroscan technology, Magnitude Geo identifies the location of reinforcement, post-tension cables, conduits and embedded services before work begins. This allows contractors, structural engineers and construction teams to plan works with confidence while reducing the risk of damaging hidden structural elements.
Professional rebar detection surveys also improve project efficiency by providing accurate information before drilling, coring or demolition. With clear on-site mark-ups, survey reports and rebar mapping where required, contractors can complete works more safely, minimise unexpected delays and avoid unnecessary repair costs.
GPR Rebar Detection
Magnitude Geo uses advanced Ground Penetrating Radar (GPR) technology to accurately detect rebar and steel reinforcement within concrete structures. GPR is a fast, non-destructive scanning method that uses high-frequency electromagnetic waves to identify hidden objects beneath the concrete surface without causing any damage.
Our GPR rebar detection surveys accurately locate reinforcing steel, post-tension cables, conduits, embedded services and other subsurface features within concrete slabs, walls, beams and structural elements. The information gathered allows contractors and structural engineers to plan drilling, coring, cutting and refurbishment works safely while reducing the risk of damaging critical structural components.
Unlike destructive investigation methods, Ground Penetrating Radar provides real-time results, allowing our surveyors to mark out reinforcement directly on site. Where required, we also provide detailed survey reports, CAD drawings and rebar mapping to support construction, engineering and structural alteration projects across London.
Ferroscan Surveys for Rebar Detection
Ferroscan surveys are used to locate steel reinforcement within concrete structures before drilling, coring, cutting or structural alterations. This non-destructive surveying method helps identify the position and cover depth of reinforcing steel, allowing contractors and structural engineers to work safely while protecting the integrity of the structure.
Magnitude Geo uses Ferroscan technology alongside advanced Ground Penetrating Radar (GPR) surveys where appropriate to provide accurate reinforcement detection. Combining multiple surveying methods allows us to identify rebar, reinforcement, post-tension cables and other embedded features within concrete, providing reliable information before construction or refurbishment works begin.
Our experienced surveyors assess each project individually to determine the most suitable scanning method. Whether using GPR, Ferroscan or a combination of both technologies, our surveys deliver accurate on-site mark-ups, detailed reports and rebar mapping to help contractors, engineers and property professionals complete projects safely and efficiently.
Rebar Mapping & Survey Drawings
In addition to locating reinforcement within concrete, Magnitude Geo provides professional rebar mapping and survey drawings to support contractors, structural engineers and project managers. Our detailed surveys accurately record the location of reinforcing steel, post-tension cables and embedded services, providing clear information before structural alterations, drilling, coring or demolition works begin.
Where required, our survey findings can be supplied as marked-up site plans, annotated survey reports and CAD drawings, allowing project teams to identify reinforcement locations with confidence. Accurate rebar mapping helps improve construction planning, reduce the risk of damaging hidden structural elements and provides valuable information for engineering and refurbishment projects.
Whether you require a simple rebar scan before drilling or comprehensive reinforcement mapping for a structural engineering project, Magnitude Geo delivers clear, accurate and reliable survey data to support safe decision-making throughout every stage of construction.
Rebar Detection Before Drilling, Coring & Cutting
Before carrying out any drilling, coring or concrete cutting works, it is essential to identify hidden reinforcement and embedded services within the structure. Professional rebar detection helps prevent damage to reinforcing steel, post-tension cables and other critical structural elements, reducing safety risks, costly repairs and unnecessary project delays.
Rebar Detection Before Drilling
Drilling into reinforced concrete without first locating rebar can damage structural reinforcement and hidden services. Our Ground Penetrating Radar (GPR) and Ferroscan surveys accurately identify reinforcement before drilling begins, allowing contractors and engineers to select safe drilling locations with confidence.
Rebar Detection Before Coring
Concrete coring is commonly carried out for new pipework, electrical services and mechanical installations. Rebar detection surveys accurately locate reinforcement, post-tension cables and embedded services before coring, helping prevent structural damage while ensuring works can be completed safely and efficiently.
Rebar Detection Before Concrete Cutting
Whether removing walls, forming new openings or carrying out structural alterations, identifying reinforcement before concrete cutting is essential. Our surveys provide accurate on-site mark-ups, rebar mapping and detailed survey information, allowing contractors and structural engineers to plan works safely while protecting the integrity of the structure.
