Overview
GPR Concrete Scanning in Slough and the M4 Corridor
Slough’s commercial and industrial building stock is dense, varied and often poorly documented. From the trading estates around Bath Road and Farnham Road to the high-rise office developments at Wellington Street and the regeneration corridors along the railway, the need for reliable pre-cut and pre-drill scanning is constant. NDTScan’s GSSI SIR 4000 GPR systems are deployed across Slough for rebar detection, post-tension cable location and embedded service mapping. We work alongside structural engineers, principal contractors and specialist subcontractors throughout SL1, SL2 and SL3, returning clean annotated scan data within an agreed number of working days.
Ultrasonic Pulse Velocity Testing in Langley, Cippenham and Colnbrook
The warehouse and light industrial units in Langley, Cippenham, Colnbrook and Poyle represent a substantial estate of mid-century and later reinforced concrete construction. Owners, occupiers and surveyors instruct NDTScan for non-destructive concrete condition assessments when visual signs of deterioration, settlement or chemical attack are present. We use the Proceq Pundit PL-200 to assess wave transmission velocity, with results interpreted against BS EN 12504 benchmarks and presented in plain-language reports suitable for planning applications, insurance schedules and structural appraisals throughout Berkshire.
Compressive Strength Assessment in Slough
Where original concrete specification is unknown or degradation is suspected, NDTScan performs integrated compressive strength assessment using calibrated rebound hammer and Olympus 38DL Plus ultrasonic methods. We have assessed concrete elements in Slough town centre retail units, car park structures along William Street, basement slabs in commercial premises affected by water ingress, and roof structures in trading estate units with suspected frost damage. All outputs are referenced to BS EN 13791 and include confidence-interval estimates of in-situ compressive strength suitable for structural review.
RAAC Surveys in Slough and the Berkshire School Estate
Reinforced autoclaved aerated concrete has been identified in a number of Berkshire schools, council buildings and NHS estate structures. NDTScan provides short-notice RAAC identification surveys using GPR and ultrasonic pulse velocity, working to IStructE guidance and DLUHC protocols. Given our proximity to Slough, the surrounding SL postcode area can be reached rapidly. Facilities managers, responsible officers and structural engineers have found this particularly valuable when urgent assessments are required ahead of term dates or inspection deadlines.
Ferroscan and Rebar Mapping for Slough Retail and Commercial Development
Before cutting, chasing, drilling or fixing into reinforced concrete elements in live commercial premises, reliable rebar mapping avoids costly delays and damage claims. NDTScan’s Hilti PS Ferroscan provides careful rebar location in walls, columns and slab soffits. We cover Slough’s high street and retail park environments, office refurbishment projects and industrial fit-outs throughout SL1 to SL3, with CAD-format outputs supplied directly to design teams and all surveys referenced to CIRIA C748.
