NDTScan carries out RAAC surveys in Pontardawe 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 Neath Port Talbot. NDTScan is the UK's specialist in identifying it, assessing it and telling an owner plainly what to do next.
The published RAAC lists cover education and NHS estates, and none of them names a Pontardawe building. NDTScan treats that as an absence of surveys rather than an absence of RAAC. Planks of this kind were installed across Neath Port Talbot from the late 1950s to the mid 1990s in public buildings, housing, leisure centres and commercial units, and the owner of a flat-roofed building of that age has no way of knowing without an identification survey.
NDTScan surveys RAAC in Pontardawe 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 Pontardawe, 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 Pontardawe client, and the reason NDTScan reports what the concrete contains before anyone specifies what to do about it.
Services Available in Pontardawe
- RAAC Identification Survey GPR based, plank by plank identification of reinforced autoclaved aerated concrete in roofs, floors and walls across Pontardawe. Confirms what the element is made of without opening it up, and records plank widths, reinforcement and bearing details as evidence.
- RAAC Condition Assessment Plank level inspection of confirmed RAAC for cracking, deflection, bearing length, water ingress, corrosion and previous repairs, classified in line with IStructE guidance. Reported so a Neath Port Talbot engineer or estates team can act on it directly.
- RAAC Management and Reinspection Monitoring regimes, reinspection intervals and management plans for RAAC that is being kept in service, plus expert input where a Pontardawe owner needs an independent second opinion on a survey or a remediation proposal.
RAAC in and around Pontardawe
Instructions in and around Pontardawe follow the RAAC lifecycle. Identification surveys where the construction of a flat or shallow roof is uncertain. Condition assessment of planks already known to be RAAC. Risk classification to IStructE guidance to support closure, propping or continued use decisions. Management plans and reinspection for planks kept in service. Independent review where a Neath Port Talbot owner has been given a survey or a remediation quote and wants a second opinion before spending. NDTScan works for the Welsh Government and NHS Wales funded bodies as well as private owners, and attends Pontardawe from its Oxford base.
