Cracked aerated concrete plank removed from a roof, NDTScan RAAC survey

Overview

RAAC surveys in Garelochhead are carried out by NDTScan, the UK's specialist in the identification and analysis of reinforced autoclaved aerated concrete. The planks were installed in Argyll and Bute buildings for nearly forty years, mainly in flat and shallow-pitched roofs, and they are now well beyond the design life their manufacturers assumed. Identifying them is the first step; understanding their condition is the one that matters.

The published RAAC lists cover education and NHS estates, and none of them names a Garelochhead building. NDTScan treats that as an absence of surveys rather than an absence of RAAC. Planks of this kind were installed across Argyll and Bute 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 Garelochhead 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.

NDTScan's advice to Garelochhead owners is consistent: survey before you decide. A RAAC roof that has been identified and assessed plank by plank can be managed, propped, strengthened or replaced on evidence. One that has only been glanced at will be closed, propped or replaced on fear, and that is where budgets go. The survey is the smallest cost in the chain.

Scan before you repair. That is the standing advice for every Garelochhead client, and the reason NDTScan reports what the concrete contains before anyone specifies what to do about it.

Services Available in Garelochhead

  • RAAC Identification Survey GPR based, plank by plank identification of reinforced autoclaved aerated concrete in roofs, floors and walls across Garelochhead. 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 Argyll and Bute 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 Garelochhead owner needs an independent second opinion on a survey or a remediation proposal.

Yes. NDTScan attends Garelochhead and the rest of Argyll and Bute from its Oxford base, and works across the whole of the UK. RAAC identification and condition assessment is a core service, delivered by the company's own specialists and reported in line with IStructE guidance.
That is the normal situation. Most RAAC in the UK was installed without the word appearing on a drawing, and many buildings have lost their drawings altogether. NDTScan identifies the construction directly, plank by plank, using ground penetrating radar and the plank's physical signature, so the Garelochhead owner does not have to rely on records that were never kept.
Each confirmed plank is inspected for cracking, deflection, bearing length, water ingress and staining, corrosion of the reinforcement, previous repairs and any signs of overloading or cutting. The findings are classified in line with IStructE guidance so the Garelochhead owner can see which planks need immediate action, which need monitoring and which are sound.
Anything with a flat or shallow-pitched roof built between the late 1950s and the mid 1990s: schools, colleges, hospitals, clinics, council offices, leisure centres, community halls, housing blocks, retail units and industrial sheds. Across Argyll and Bute the education and NHS estates have been counted; the rest of the stock has not, and that is where most uninspected RAAC now sits.
Plank by plank, not as a general opinion. Each element is identified, its condition recorded and classified in line with IStructE guidance, and every significant defect is photographed and located on a plan. The report says what was found, what was not found and how confident each reading is, so the Argyll and Bute owner can act on it directly.
