Overview
Great Missenden is inside NDTScan's home territory. Working from Oxford, Neil Smuts covers Buckinghamshire, Buckinghamshire, Berkshire and Oxfordshire as a single patch, and Great Missenden projects are scanned and interpreted by the same named specialist. There is no subcontracted operator and no anonymous report.
Great Missenden has its own character for this work: a Chiltern line village with the Roald Dahl museum and HS2 tunnel portal works nearby. That mix of ages and construction types is why Great Missenden work has to start with a survey that is planned for the element in question, not a generic pass with one antenna.
The on-site capture is only the first step. NDTScan's value is in the post-processing: analysing reflections, cross-checking traces against each other, resolving ambiguous returns and producing a fully interpreted result. In Great Missenden, as everywhere else, the data is worked up in the office before a single conclusion is drawn, and the report says plainly what was found, what was not found and how confident the reading is.
Where Great Missenden clients are heading towards concrete repair, NDTScan's position is firm: the element must be scanned and the data interpreted by a reputable specialist before any repair is designed. Anything else risks treating the symptom and leaving the cause in place. The findings feed straight into the repair specification.
Scan before you repair. That is the standing advice for every Great Missenden client, and the reason NDTScan reports what the concrete contains before anyone specifies what to do about it.

Method and antenna selected for the Great Missenden 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.

Typical Great Missenden Projects
Around Great Missenden the instructions NDTScan receives are shaped by railway structures and station buildings and former industrial and institutional buildings being brought back into use. 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 Prestwood, Wendover and Amersham 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. Great Missenden 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
Great Missenden Concrete Scanning FAQs
Frequently Asked Questions.
What Buckinghamshire clients ask before instructing a concrete scan in Great Missenden, and how NDTScan answers.
Do you provide concrete scanning in Great Missenden?
Yes. Great Missenden is in Buckinghamshire, which NDTScan covers from its Oxford base along with Buckinghamshire, Berkshire and Oxfordshire. Neil Smuts carries out and interprets the survey personally, so the person on site in Great Missenden is the person who writes the report.
Which problems does concrete scanning in Great Missenden solve?
Three above all. What a Great Missenden slab or wall contains before it is drilled, cored or cut. Where the data indicates the reinforcement and any post-tensioning sit before a structural alteration. And what an existing structure contains before anyone specifies a repair. GPR answers most of these; Ferroscan and ultrasonic methods are added where the element demands them.
Do you carry out RAAC surveys in Great Missenden and the rest of Buckinghamshire?
Yes, regularly. RAAC identification surveys are a standing part of NDTScan's Buckinghamshire work, in schools, halls, housing and healthcare buildings. GPR is used to separate RAAC planks from conventional reinforced concrete, and the findings are reported in line with IStructE guidance so the building owner can act on them.
Why should I scan before drilling or repairing concrete in Great Missenden?
Because the drawings are not the structure. Post-tensioned tendons, live services and undocumented reinforcement are all commonly found where nobody expected them, and striking any of them is expensive at best. On repairs the argument is stronger still: a repair specified without a proper survey and interpretation is a repair to a guess. NDTScan's rule for Great Missenden and everywhere else is scan first, interpret properly, then design.
What equipment does NDTScan use on Great Missenden concrete scanning projects?
GSSI SIR 4000 and Mala ground penetrating radar systems for the scanning itself, the Hilti PS Ferroscan for high resolution rebar mapping in tight spaces, and the Proceq Pundit PL-200 for ultrasonic pulse velocity and pulse echo work. The choice for a Great Missenden element is made by the method the element needs, and the interpretation of the data matters more than any single instrument.
