GPR Concrete Slab Surveys
Subvision Surveys carries out GPR concrete slab surveys, using ground-penetrating radar to non-destructively scan and map the interior of a concrete slab. This identifies embedded objects, rebar, post-tension cables, voids and slab thickness, without any drilling, cutting or damage to the structure being surveyed.
What a GPR Concrete Slab Survey Reveals
Our surveyors scan the slab on a regular grid, recording variations in the radar signal as it passes through the concrete. This builds an accurate picture of what’s inside the slab, rebar position and cover depth, the presence of post-tension cables, any voids or delamination, and the overall thickness of the concrete itself. Having this information before drilling, cutting or coring work begins reduces the risk of striking reinforcement or embedded services, and helps catch structural issues, such as voiding, before they develop into a more serious problem.
The Role of GPR Concrete Slab Surveyors
GPR Concrete Slab Surveyors are trained professionals who operate advanced GPR equipment to conduct these surveys. They analyse the radar data to provide accurate and comprehensive insights into the slab’s condition.
Different Surveys for Different Needs
Not every project needs the same level of detail. A GPR concrete floor slab survey focuses specifically on the internal structure of a floor, useful ahead of general construction or renovation work. Where the concern is specifically about whether a slab meets its design specification, our Slab Thickness Measurement Surveys offer a more targeted check, measuring concrete thickness across a surveyed area rather than covering rebar, voids and services all at once. We help clients choose the right scope for their project, rather than defaulting to the same survey regardless of what’s actually needed.
Why Choose Subvision for GPR Concrete Slab Surveys
Subvision Surveys is SSIP and ISO accredited, with a team of over 25 surveying professionals delivering GPR concrete slab surveys for contractors, developers and building owners across London, the South East and nationwide. We’re Essex-based but work across the UK, using specialised techniques and cutting-edge equipment to deliver accurate results at competitive rates for Tier 1 contractors, developers, planners and private individuals alike. Where a project specifically needs reinforcement located ahead of drilling or coring, we also offer dedicated Ferro Scanning, using the same GPR-based approach tailored to rebar detection.
