NDTScan carries out RAAC surveys in Wath upon Dearne for schools, hospitals, councils, housing providers, universities and commercial owners. Reinforced autoclaved aerated concrete was used in roofs, floors and walls from the late 1950s to the mid 1990s, and a great deal of it is still in service across South Yorkshire. NDTScan is the UK's specialist in identifying it, assessing it and telling an owner plainly what to do next.
The Department of Health and Social Care's list of hospital sites with confirmed RAAC includes Northern General Hospital and Barnsley Hospital in South Yorkshire. Those are the buildings that made the published lists, which cover schools, colleges and NHS sites. They are named here as evidence that the construction is present in South Yorkshire, not as NDTScan projects. Around Wath upon Dearne the same roof and floor planks are in council buildings, housing, leisure centres, retail units and industrial sheds that nobody has counted.
NDTScan surveys RAAC in Wath upon Dearne in two stages that are usually completed on the same visit. First, identification: GPR and the plank's own signature, its width, its transverse reinforcement and its bearing detail, establish plank by plank whether the element is RAAC at all. Second, condition: each confirmed plank is inspected for cracking, deflection, bearing length, water ingress, corrosion and past repair, and the results are classified in line with IStructE guidance. The report says what was found, what was not found and how confident each reading is.
The most expensive mistake in Wath upon Dearne, as everywhere else, is to act on RAAC before it has been understood. Whole buildings have been closed on the strength of a visual inspection that could not tell RAAC from hollowcore. NDTScan's position is that identification and condition assessment come first, remediation second, and the report has to be good enough to design from.
Scan before you repair. That is the standing advice for every Wath upon Dearne client, and the reason NDTScan reports what the concrete contains before anyone specifies what to do about it.
