Overview

Chesham Bois is inside NDTScan's home territory. Working from Oxford, Neil Smuts covers Buckinghamshire, Buckinghamshire, Berkshire and Oxfordshire as a single patch, and Chesham Bois projects are scanned and interpreted by the same named specialist. There is no subcontracted operator and no anonymous report.

Chesham Bois sits within Buckinghamshire, and the work here follows the pattern of the wider county: 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 Chesham Bois, 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 Chesham Bois 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 Chesham Bois client, and the reason NDTScan reports what the concrete contains before anyone specifies what to do about it.

Services Available in Chesham Bois

  • 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 Chesham Bois 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 Chesham Bois structures.

Typical Chesham Bois Projects

In and around Chesham Bois, NDTScan is most often asked for pre-drill and pre-coring surveys, post-tension detection in suspended slabs, RAAC identification in education and community buildings, rebar and cover mapping to support engineering assessments, and interpreted investigation of existing concrete before any repair is designed.

NDTScan also covers Amersham, Chesham and Little Chalfont and the rest of Buckinghamshire. Every one of these areas is reached from the Oxford base without a subcontractor in the chain.

Why Choose NDTScan

Chesham Bois Concrete Scanning FAQs

Frequently Asked Questions.

What Buckinghamshire clients ask before instructing a concrete scan in Chesham Bois, and how NDTScan answers.

Is Chesham Bois within NDTScan's normal working area?

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

What will a concrete scan tell me about a Chesham Bois 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 Chesham Bois 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.

How is RAAC identified in Chesham Bois 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 a Chesham Bois building are reported in line with IStructE guidance, so the owner has a record that supports the decisions that follow.

What happens if a Chesham Bois contractor drills without scanning?

Usually nothing, until it does. Post-tensioned tendons, live services and undocumented reinforcement are routinely found where nobody expected them, and striking one turns a fixing into a structural incident. A pre-drill scan in Chesham Bois replaces guesswork with evidence, and NDTScan's interpreted report sets out what the data indicates, at what estimated depth, and with what confidence.

What do I receive after a concrete scan in Chesham Bois?

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 Chesham Bois, and it stands up to design, dispute and audit scrutiny.
