Ground penetrating radar (GPR) only needs access to one side of the concrete. X-ray needs access to both sides, which rules it out for slab-on-grade.
GPR uses no radiation. Nobody needs to leave the area, so other trades can keep working nearby.
GPR results are available on site. Findings are marked on the slab as we scan, so you can core or cut once the marks are down.
On cost, GPR is generally the cheaper option. There is no evacuation, no film processing and less disruption to the rest of the site. Each job is different, so ask us which method fits your slab.
Our Proceq GP8000 and GP8800 handheld units can scan through 24+ inches of concrete.
Real results depend on the slab. Dense rebar can hide what sits below it, and moisture in the concrete reduces how deep the signal travels. We will tell you on site if conditions are limiting what we can see.
GPR can locate rebar, post-tension cables, conduits, heat pipes and voids, and it can measure slab thickness. No scanning method can promise to find everything, which is why good drawings and site information help.
Yes, you get results the same day. Findings are marked on the concrete during the scan, and on-site data processing and real-time reporting are available.
For basic services, a jobsheet is sent the same day.
Written reports have a default turnaround of one week. Smaller reports may be faster and larger ones may take longer. We agree on the timeline with you before work starts.
