For concrete scanning in Stone, NDTScan offers something most scanning contractors do not: a named specialist who does the site work and the interpretation. Neil Smuts leads every Buckinghamshire survey from NDTScan's Oxford base, and the report you receive is his reading of the data, not a set of marks left on a slab.
Stone lies in Buckinghamshire, and what NDTScan is asked to look at here reflects Buckinghamshire as a whole: Chiltern market towns, post-war new town estates and a large stock of mid-century schools, hospitals and council housing. 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.
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 Stone, 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 Stone 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 Stone client, and the reason NDTScan reports what the concrete contains before anyone specifies what to do about it.
Services Available in Stone
- 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 measurement and RAAC identification. Method and antenna selected for the Stone 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 Stone structures.
Typical Stone Projects
The work NDTScan is instructed for around Stone follows the shape of Buckinghamshire: pre-drill and pre-coring scans in occupied houses and commercial units, post-tensioned slab checks before fixings or penetrations, RAAC identification in schools, halls and public buildings, cover and rebar surveys ahead of structural alterations, and investigation of existing slabs and frames before repair or redesign.
NDTScan also covers Aylesbury, Haddenham and Waddesdon and the rest of Buckinghamshire. Every one of these areas is reached from the Oxford base without a subcontractor in the chain.
