GPR Concrete Scanning Marlow | Local Specialist | NDTScan

GPR Concrete Scanning in Marlow and the Wye Valley Corridor

Marlow sits at the confluence of Buckinghamshire commuter belt development and a historic riverside townscape of considerable architectural variety. From Victorian riverside villas and converted mill buildings along the Thames to commercial premises on the A4155 and newer residential developments in Marlow Bottom and Little Marlow, the range of structural concrete encountered is wide. NDTScan’s GSSI SIR 4000 ground-penetrating radar provides pre-cut rebar detection, post-tension cable mapping and embedded service location across all of it. We attend at short notice and deliver fully annotated scan data the same day throughout the SL7 postcode area.

Ultrasonic Testing in Marlow, Bourne End and Flackwell Heath

The Thames Valley corridor through Marlow, Bourne End and up towards Wooburn Green, Flackwell Heath and Loudwater contains a significant stock of concrete-framed buildings from the 1950s through to the 1990s. Offices, industrial units, schools and residential blocks in this area regularly present for condition assessment when change of use, sale or structural concern triggers an investigation. NDTScan uses the Proceq Pundit PL-200 to perform ultrasonic pulse velocity testing on site, with results referenced to BS EN 12504 and supplied in professional reports suitable for structural engineers, planning consultants and building surveyors throughout the Wycombe district.

Compressive Strength Assessment for Marlow Structures

When original concrete specification is unavailable or where environmental exposure has raised concerns about strength, NDTScan provides integrated compressive strength testing in Marlow and the wider SL7 area. We use the Olympus 38DL Plus and calibrated rebound hammer methodology, referenced to BS EN 13791, providing confidence-interval strength estimates that enable informed decisions on whether intrusive sampling is warranted. We have assessed structures at commercial addresses along Dean Street, riverside apartment blocks and converted industrial buildings throughout the Wycombe district.

RAAC Surveys in Marlow and the Wycombe District

Reinforced autoclaved aerated concrete surveys are increasingly instructed by academy trusts, local authority estate teams and NHS property managers across Buckinghamshire. NDTScan’s RAAC identification service uses GPR and UPV methods in combination, following IStructE guidance and DLUHC protocols. From Marlow, we reach Wooburn Green, Loudwater, High Wycombe and Penn within minutes, making us a practical choice for district-wide estate assessment programmes where time and attendance reliability both matter.

Ferroscan Surveys for Marlow’s Listed and Heritage Buildings

Marlow has a high concentration of listed buildings, particularly along the High Street, Thames embankment and within the town’s conservation area. Where structural works touch historic fabric, the Hilti PS Ferroscan provides accurate reinforcement location with minimal surface contact. NDTScan has used the Ferroscan in converted coaching inns, period commercial properties and Victorian residential structures throughout Marlow town centre and surrounding parishes, providing CAD-format reinforcement maps and written condition notes for heritage consultant review in line with CIRIA C748.
