Overview

For a RAAC survey in East Leake, NDTScan brings something no general scanning contractor can: hands-on experience of identifying and analysing reinforced autoclaved aerated concrete across the UK, in schools, hospitals, housing, public buildings and commercial estates. Nottinghamshire has its share of the roofs and floors built with these planks between the late 1950s and the mid 1990s, and most have never been properly surveyed.

The Department for Education's list of education settings with confirmed RAAC, published in February 2024, includes one setting in Nottinghamshire, among them Holy Trinity Catholic Voluntary Academy. The Department of Health and Social Care's list of hospital sites with confirmed RAAC includes Bassetlaw District General Hospital in Nottinghamshire. NDTScan cites the published lists as evidence that RAAC is in the Nottinghamshire building stock, and for no other reason. Education and health estates were counted because government asked for them to be counted. The equivalent stock in East Leake's council, housing, leisure, retail and commercial buildings has not been, and that is where most uninspected RAAC now sits.

The method NDTScan uses in East Leake 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 East Leake owner receives a plank-level record, not a general opinion.

NDTScan's advice to East Leake 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 East Leake client, and the reason NDTScan reports what the concrete contains before anyone specifies what to do about it.

Services Available in East Leake

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

RAAC in and around East Leake

Around East Leake the work divides into four kinds. Owners who do not know what their roof is made of and need it identified. Owners who know it is RAAC and need every plank assessed and classified in line with IStructE guidance. Estates teams who need a management plan and a reinspection regime for planks staying in service. And Nottinghamshire clients who have a survey or a remediation proposal in front of them and want NDTScan's independent view before committing money. Public bodies, housing providers, insurers and private owners all instruct on the same basis.

NDTScan also provides RAAC surveys in Nottingham, Mansfield, Carlton, Beeston, Worksop and Arnold and the rest of Nottinghamshire. The rest of the region is covered from the East Midlands RAAC surveys page, and the service itself is described on the RAAC surveys page.

Yes. NDTScan attends East Leake and the rest of Nottinghamshire 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.
With ground penetrating radar and the plank's own signature. RAAC planks return a distinctly different radar response from dense concrete, hollowcore and timber, and their widths, transverse bars and bearing details confirm the reading. NDTScan checks every plank rather than sampling one corner, so a East Leake owner gets a complete picture without opening the roof.
It will give the owner's engineer the evidence needed to make that decision. NDTScan records the condition of every plank, classifies the findings in line with IStructE guidance and states plainly where immediate action is needed. The decision on occupation rests with the responsible engineer, and the report is written so that decision can be taken on evidence rather than on fear.
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 Nottinghamshire the education and NHS estates have been counted; the rest of the stock has not, and that is where most uninspected RAAC now sits.
NDTScan's own specialists, not a subcontractor. The company is the UK's specialist in RAAC identification and analysis, and the person who reads the radar data and classifies the planks is a specialist in this material. The East Leake report is the interpretation, not a set of marks on a ceiling.
