RAAC Scanning in Woodley
Structured Carbon provides non-destructive RAAC scanning in Woodley and throughout Berkshire. The work is led by Neil Smuts (MCIOB, MInstNDT, FRCSP), President of the UK Concrete Scanning Standard and a Fellow of the Register of Concrete Scanning Professionals, the person who leads the national standard for concrete scanning. The scan confirms RAAC, maps the reinforcement, and gives John Staves (CEng FIStructE, MIoD), a chartered structural engineer and one of the UK's leading specialists in RAAC, the evidence his assessment needs.
- Led by Neil Smuts, President of the UK Concrete Scanning Standard and Fellow of the Register of Concrete Scanning Professionals
- Confirms RAAC and locates its reinforcement without opening up the structure
- Building stays in use; quiet, room-by-room work
- Results feed straight to a chartered RAAC engineer, John Staves CEng FIStructE MIoD
Based in Finchampstead, Wokingham. Woodley is local to us.
How scanning identifies RAAC
Two things cannot be seen from below a ceiling: whether a panel is RAAC at all, and where its reinforcement is. Scanning answers both. It separates RAAC from dense concrete by its internal structure, and it maps the reinforcement in each plank, including whether the bars reach the bearings, which is where RAAC planks are most likely to fail. The results are logged to a location plan for every panel scanned, ready for structural assessment.
Scanning led by the national standard
Our scanning is led by Neil Smuts (MCIOB, MInstNDT, FRCSP), President of the UK Concrete Scanning Standard and a Fellow of the Register of Concrete Scanning Professionals. The UK Concrete Scanning Standard is the national standard for concrete scanning, and Neil leads it. That matters because scanning is only as good as the person interpreting it: RAAC, voids, dense concrete and previous repairs can all look alike to an untrained operator. Every scan we carry out in Woodley is read by the person who owns the Assess stage of our RAACSafe™ Protocol, and the results go directly to John Staves (CEng FIStructE, MIoD), a chartered structural engineer and one of the UK's leading specialists in RAAC, for assessment.
GPR and ultrasonic RAAC scanning for schools, hospitals and councils in Woodley
We scan with ground penetrating radar (GSSI Flex NX, GSSI StructureScan Mini, Proceq GP8800 and GP8100) and ultrasonic tomography (Proceq Pundit PD8050), read by Neil Smuts (MCIOB, MInstNDT, FRCSP), President of the UK Concrete Scanning Standard and a Fellow of the Register of Concrete Scanning Professionals. For a school or academy in Woodley that means a quiet visit around the timetable; for an NHS estate or council building it means the building stays open. The scan confirms the material, maps the reinforcement and records bearing length for the engineering inspection. Scanning is part of the visual survey, from £395, and of every engineering inspection, which is priced per building.
RAAC in Woodley
Woodley sits in the Wokingham Borough Council area, close to Earley, Reading and Twyford. It is a large post-war residential town east of Reading built on the former Woodley aerodrome, with the Headley Road business area, and it holds a town built almost entirely in the post-war decades, so its schools, halls and shopping precinct are of the RAAC period. That is the building stock the RAAC scanning question applies to: anything with a flat or shallow roof from the 1950s to the mid 1990s, whether school, clinic, hall, leisure centre or office.
A practical starting point in Woodley
If you are responsible for buildings in Woodley, start with a list. Which of them have flat or low-pitched roofs, and which were built or extended between the 1950s and the mid 1990s? In the Wokingham Borough Council area that will usually take in a town built almost entirely in the post-war decades, so its schools, halls and shopping precinct are of the RAAC period. Anything on that list that has never had RAAC ruled in or out is a candidate for a RAAC scanning. Send us the list and we will tell you which buildings justify a visit, and which can be cleared from the desk with drawings alone.
Scan, survey, assess
Two routes are common in Woodley. Where nobody knows what the roof is made of, scanning is the first step and usually happens inside a full RAAC survey. Where a visual survey has already said "probably RAAC", scanning is the confirmation, and it often adds the one fact the visual survey could not: whether the reinforcement reaches the bearings. In both cases the results go to John Staves (CEng FIStructE, MIoD), a chartered structural engineer and one of the UK's leading specialists in RAAC, for a RAAC assessment that answers the strengthen-or-replace question. Across the RAAC tenders we cost, a bespoke CFRP scheme engineered for that exact roof frequently comes in at well below 15 per cent of the cost of full replacement. On one tender, a roof costed at around £40 million to replace was priced for strengthening at under £4 million.
What we bring to Woodley
We have surveyed thousands of square metres of RAAC, using GSSI Flex NX and GSSI StructureScan Mini ground penetrating radar, Proceq GP8800 and GP8100 radar, the Proceq Pundit PD8050 ultrasonic tomograph, and other electromagnetic and ultrasonic NDT instruments. We can usually be on site in Berkshire within one to two days, evening, weekend and holiday visits are no problem, and the report follows within five working days of the site visit, depending on the size of the survey and the level of detail required. Professional indemnity insurance is held to a maximum of £10 million, with public and employers' liability arranged on a per-site basis.

RAAC scanning FAQs
Do you scan the whole roof?
We scan every accessible panel that could be RAAC, recorded to a location plan. For a large estate in Woodley we agree the scope with you first, but the principle is that unscanned panels are unknown panels.
Who interprets the results?
Neil Smuts (MCIOB, MInstNDT, FRCSP), President of the UK Concrete Scanning Standard and a Fellow of the Register of Concrete Scanning Professionals, leads and reads every scan. The results go to John Staves (CEng FIStructE, MIoD), a chartered structural engineer and one of the UK's leading specialists in RAAC, for structural assessment.
Can you scan a school in Woodley during term?
Yes. Scanning is quiet, room-by-room work. We plan it around the timetable or use holidays and out-of-hours periods where a school prefers.
Is scanning enough on its own?
It confirms the material and maps the reinforcement. To know what condition the panels are in and what to do, you need the condition survey and a structural assessment as well. We offer all three together as a RAAC survey in Woodley.
What areas do you cover?
We are based in Finchampstead, Wokingham, so Woodley is on our doorstep. Berkshire, Hampshire, Surrey, Oxfordshire and Buckinghamshire are local to us, and we scan RAAC across the UK.
What scanning equipment do you use?
GSSI Flex NX and GSSI StructureScan Mini ground penetrating radar, Proceq GP8800 and GP8100 radar, the Proceq Pundit PD8050 ultrasonic tomograph, and other electromagnetic and ultrasonic NDT instruments. We have surveyed thousands of square metres of RAAC with them.
How soon can you scan a building in Woodley?
We can usually be on site in Berkshire within one to two days, and evening, weekend and holiday visits are no problem. The report follows within five working days of the site visit, depending on the size of the survey and the level of detail required.
