Overview
NDTScan provides concrete scanning in Iver as part of its core Buckinghamshire 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 Iver clients that means one accountable specialist from the first call to the final report.
In Iver the local context is clear enough: close to the M25 and M4 junction, with the Ridgeway trading estate, rail freight land and Elizabeth line works at Iver station. Wherever the work sits in Buckinghamshire, the question NDTScan is answering is what the concrete actually contains, and how much of it can be trusted.
What separates a dependable concrete scan from a superficial one is the interpretation. NDTScan concentrates most of its effort after the site visit: reviewing every radargram, correlating GPR with Ferroscan and ultrasonic data where the element demands it, and writing a report that an engineer can act on. Iver clients receive that standard of work as a matter of course.
NDTScan will always say this to an Iver client considering repairs: scan first. A repair specified without a proper survey and an expert interpretation is a repair to a guess. The survey establishes what is really there, so the engineer can design for the structure that exists rather than the one on the drawings.
Scan before you repair. That is the standing advice for every Iver client, and the reason NDTScan reports what the concrete contains before anyone specifies what to do about it.
Services Available in Iver

Method and antenna selected for the Iver 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 Buckinghamshire 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 Iver structures.
Typical Iver Projects
Around Iver the instructions NDTScan receives are shaped by railway structures and station buildings, highway structures and the logistics sheds that cluster around the junctions and commercial and laboratory floors where post-tensioned slabs are common. Alongside those sit the constants of every Buckinghamshire 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 Iver Heath, Slough and Langley and the rest of Buckinghamshire. 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. Iver and the whole of Buckinghamshire 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
Iver Concrete Scanning FAQs
Frequently Asked Questions.
Common questions about GPR concrete scanning, ultrasonic testing and compressive strength assessment in Iver and across Buckinghamshire. NDTScan works from its Oxford base with fully interpreted reporting.
Is Iver within NDTScan's normal working area?
It is. NDTScan works from Oxford across Buckinghamshire and the two neighbouring counties, and Iver sits comfortably inside that patch. Every survey is carried out and interpreted by Neil Smuts, so the specialist on site in Iver is the one who writes the report.
What can a GPR concrete scan in Iver actually find?
Ground penetrating radar indicates the position and estimated depth of reinforcing bars and mesh, post-tensioned tendons, conduits and services, voids and honeycombing, and estimates slab thickness and cover. In Iver that most often means establishing what a slab or wall contains before drilling or coring, locating reinforcement before an alteration, or characterising a structure before repair. Where GPR cannot resolve a question, NDTScan adds Ferroscan or ultrasonic methods.
How is RAAC identified in Iver schools and public buildings?
With ground penetrating radar. RAAC planks return a distinctly different signature from conventional reinforced concrete, and NDTScan reads that signature element by element rather than sampling a corner and assuming the rest. The findings for an Iver building are reported in line with IStructE guidance, so the owner has a record that supports the decisions that follow.
Is a scan really necessary before concrete repairs in Iver?
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 Iver 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 Iver?
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 Iver, and it stands up to design, dispute and audit scrutiny.
