Overview
NDTScan provides concrete scanning in Calcot as part of its core Berkshire coverage. The company is based in Oxford and led by Neil Smuts, who carries out and interprets the surveys himself rather than passing the data to a back office. For Calcot clients that means one accountable specialist from the first call to the final report.
In Calcot the local context is clear enough: junction 12 of the M4 with the Sainsbury's Calcot district centre, IKEA and large 1980s estates. Across West Berkshire the recurring need is the same: to know exactly what is inside a concrete element before anyone drills, cores, cuts or specifies a repair.
Most scanning companies stop at marks on the surface. NDTScan does not. Every Calcot survey goes through careful office post-processing, where reflections are analysed, ambiguities resolved and the interpretation checked against the drawings and the element's history. The result is a record the client can design from, defend in a dispute and hand to an auditor.
One caveat applies to every Calcot project. No structural repair to a concrete element should be specified or carried out until the structure has been properly scanned and the data expertly interpreted. Repairing what has not been correctly understood risks repeating the fault, and the scan is the cheapest part of getting it right.
Scan before you repair. That is the standing advice for every Calcot client, and the reason NDTScan reports what the concrete contains before anyone specifies what to do about it.
Services Available in Calcot
- GPR Concrete Scanning Pre-drill and pre-coring surveys, rebar and mesh mapping, post-tensioned tendon detection, void and honeycombing detection, slab thickness and cover estimation and RAAC identification. Method and antenna selected for the Calcot element in question, with the full interpreted record supplied.
- Ultrasonic Testing of Concrete Ultrasonic pulse velocity testing for uniformity and quality assessment, pulse echo for thickness and delamination where only one face is accessible, and the combined SONREB method for compressive strength estimation. Used across Berkshire where GPR alone cannot answer the question.
- Concrete Compressive Strength Assessment Rebound hammer surveys, UPV combined method and managed core extraction with laboratory testing to BS EN 13791. Independent reporting suitable for engineering acceptance, building control and dispute work on Calcot structures.
Typical Calcot Projects
Around Calcot the instructions NDTScan receives are shaped by highway structures and the logistics sheds that cluster around the junctions and post-war housing where non-standard construction has to be identified before any works. Alongside those sit the constants of every Berkshire town: pre-drill and pre-coring scans on occupied buildings, post-tensioned slab investigation before any fixing or penetration, RAAC identification in schools and public buildings, and structural investigation before repair.
NDTScan also covers Tilehurst, Theale and Reading and the rest of West Berkshire. Every one of these areas is reached from the Oxford base without a subcontractor in the chain.
About NDTScan
NDTScan is a specialist non-destructive testing company based in Oxford and led by Neil Smuts. Its core disciplines are GPR concrete scanning, ultrasonic testing and in-situ compressive strength assessment, brought together in its concrete scanning and structural condition survey service. NDTScan is a Level 4 UKCSS Operator, the first in the UK to achieve that certification. Calcot and the whole of Berkshire are within the company's everyday working area, and all work is reported to a standard suitable for engineering acceptance. RAAC identification is covered on the RAAC surveys page, and steel on the ultrasonic thickness and corrosion mapping page.

Why Choose NDTScan
Calcot Concrete Scanning FAQs
Frequently Asked Questions.
What Berkshire clients ask before instructing a concrete scan in Calcot, and how NDTScan answers.
Is Calcot within NDTScan's normal working area?
It is. NDTScan works from Oxford across Berkshire and the two neighbouring counties, and Calcot sits comfortably inside that patch. Every survey is carried out and interpreted by Neil Smuts, so the specialist on site in Calcot is the one who writes the report.
What will a concrete scan tell me about a Calcot building?
What the data indicates is inside the concrete and how far each reading can be trusted. A survey indicates the position and estimated depth of reinforcement, post-tensioned tendons, embedded services and voids, and estimates slab thickness and cover. For a Calcot building that is the difference between a decision made on evidence and one made on the drawings, and between a repair designed for the structure that exists and one designed for the structure someone assumed.
Can you identify RAAC in Calcot buildings?
Yes. NDTScan uses GPR to distinguish reinforced autoclaved aerated concrete planks from conventional reinforced concrete, and reports the findings in a form that supports the building owner's duties under IStructE guidance. RAAC identification is a regular instruction across Berkshire schools, halls, housing and healthcare stock, and Calcot is no exception.
Is a scan really necessary before concrete repairs in Calcot?
Yes. A repair specified without a proper scan and an expert interpretation is a repair to a guess, and it risks repeating the fault that caused the damage. The survey establishes what the Calcot element actually contains and how it is behaving, so the engineer designs for the structure that exists. The scan is the cheapest part of getting the repair right.
What do I receive after a concrete scan in Calcot?
A fully interpreted report, not a photograph of marks on a slab. The data is post-processed in the office, cross-checked and written up with clear statements of what was found, what was not found and the confidence attached to each. It is written for the engineer or contractor who has to act on it in Calcot, and it stands up to design, dispute and audit scrutiny.
