NDTScan carries out RAAC surveys in New Stevenston 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 North Lanarkshire. NDTScan is the UK's specialist in identifying it, assessing it and telling an owner plainly what to do next.
Motherwell Concert Hall and Theatre has also been publicly reported as containing RAAC. 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 North Lanarkshire, not as NDTScan projects. Around New Stevenston the same roof and floor planks are in council buildings, housing, leisure centres, retail units and industrial sheds that nobody has counted.
The method NDTScan uses in New Stevenston is the one it uses everywhere: identify first, then assess. Ground penetrating radar reads the plank's internal structure without cutting into it, distinguishing RAAC from the dense precast, hollowcore and timber it is often mistaken for. Every confirmed plank is then inspected for the defects that matter, cracking, deflection, short bearing, water damage, corrosion and earlier repairs, and classified in line with IStructE guidance. The New Stevenston owner receives a plank-level record, not a general opinion.
NDTScan's advice to New Stevenston 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 New Stevenston client, and the reason NDTScan reports what the concrete contains before anyone specifies what to do about it.
Services Available in New Stevenston
- RAAC Identification Survey GPR based, plank by plank identification of reinforced autoclaved aerated concrete in roofs, floors and walls across New Stevenston. 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 North Lanarkshire engineer or estates team can act on it directly.
