Overview

For concrete scanning in Caversham, NDTScan offers something most scanning contractors do not: a named specialist who does the site work and the interpretation. Neil Smuts leads every Berkshire 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.

Caversham has its own character for this work: the north bank of Reading, with Victorian and Edwardian housing, Caversham Bridge and Reading Bridge and hillside 1930s estates. That mix of ages and construction types is why Caversham 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 Caversham, 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.

One caveat applies to every Caversham 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 Caversham client, and the reason NDTScan reports what the concrete contains before anyone specifies what to do about it.

Services Available in Caversham

  • 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 Caversham 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 Caversham structures.

Typical Caversham Projects

Around Caversham the instructions NDTScan receives are shaped by post-war housing where non-standard construction has to be identified before any works and bridge decks, river walls and flood defence structures. 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 Reading, Sonning and Emmer Green and the rest of Reading Borough. 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. Caversham 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

Caversham Concrete Scanning FAQs

Frequently Asked Questions.

Common questions about GPR concrete scanning, ultrasonic testing and compressive strength assessment in Caversham and across Berkshire. NDTScan works from its Oxford base with fully interpreted reporting.

Is Caversham within NDTScan's normal working area?

It is. NDTScan works from Oxford across Berkshire and the two neighbouring counties, and Caversham sits comfortably inside that patch. Every survey is carried out and interpreted by Neil Smuts, so the specialist on site in Caversham is the one who writes the report.

What will a concrete scan tell me about a Caversham 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 Caversham 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 Caversham 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 Caversham is no exception.

Why should I scan before drilling or repairing concrete in Caversham?

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 Caversham and everywhere else is scan first, interpret properly, then design.

What equipment does NDTScan use on Caversham 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 Caversham element is made by the method the element needs, and the interpretation of the data matters more than any single instrument.
