Our core service
GPR surveys
Non-destructive scanning of ground, concrete and structures. Rebar and post-tension cables, slab thickness, voids, obstructions, graves and archaeology.

GPR surveys and utility mapping
See what's under the surface before you dig, drill or cut
KB GPR Surveys locates buried services, rebar, post-tension cables, voids and obstructions using ground penetrating radar and electromagnetic location. You get clear CAD drawings and a plain-English report.

What we survey
Three core services
PAS 128 quality levels D to B
Utility surveys
Buried services located with electromagnetic location and GPR, then drawn to PAS 128 so designers and groundworkers know what is there and how sure we are.
Utility survey servicesOften combined with utilities
Topographical surveys
Levels, features and boundaries surveyed to the same grid as your utility survey, delivered as one CAD drawing.

What we scan for
Each application has its own method, antenna frequency and deliverable. Choose the one closest to your job.

How a job runs
From enquiry to drawing
Send us the site
Address, a marked-up plan and what you need to know. Photos help.
Fixed quotation
We price the site time, processing and drawings, and confirm what the survey can and can't tell you.
Site survey
GPR and EML scanning, marking out on the ground where needed, with RAMS issued before we arrive.
Drawings and report
CAD drawings in PDF and DWG with a report, normally within 15 working days of the survey.
Who we work for
Contractors, consultants and councils
We work as a subcontractor to surveying firms and main contractors, and directly for engineers, councils and property owners.

“We trust KB to complete our PAS 128 utility mapping surveys with GPR because their experience, high standards and quality control give us confidence the results can be relied upon.”
“Their attention to detail and accuracy made all the difference to avoiding utility strikes, and we won't hesitate to use them again.”
“KB completed our GPR investigations and, in spite of some setbacks, delivered on time. Their ingenuity kept the difficulties from affecting the overall programme.”
Coverage
Based in Southampton, working across England and Wales
Our office is in West End, Southampton, so most of our work is across the south: Hampshire, Dorset, Wiltshire, Sussex, Surrey and London. We regularly travel further for larger jobs and for repeat clients.
The team comes from geophysics, geology and archaeology, and GPR has been the core of the business since we started. That matters most on difficult sites: congested services, heavily reinforced slabs, and ground where radar struggles. We will tell you when GPR is the wrong tool before you pay for it.
