NDTScan is based in Oxford, making us the natural first call for concrete scanning and non-destructive testing projects across Oxfordshire and the surrounding counties. Our Oxford-based team provides same-day attendance for most city and county projects.
Oxford presents a genuinely varied built environment for concrete scanning work. The city combines Victorian and Edwardian commercial and residential stock with a very large mid-century concrete university and NHS estate, and a growing programme of residential development and basement construction in the suburban fringe. Each creates distinct scanning demands.
The University of Oxford and Oxford University Hospitals NHS Foundation Trust together represent one of the largest concentrations of research, teaching, and healthcare buildings in the country. Much of this estate was constructed in reinforced and post-tensioned concrete between the 1950s and 1990s. Pre-drill scanning in these buildings is both a statutory requirement on post-tensioned elements and a practical necessity given the density of building services within concrete structures built during that era.
Residential basement construction in Oxford and North Oxford has increased significantly in recent years. Pre-drill and structural scanning for basement projects is a regular requirement, and NDTScan understands the constraints of working in occupied residential properties: quiet equipment, rapid turnaround, and clear communication with both the homeowner and contractor.
Local authority and housing association estates across Oxford include a proportion of stock built using non-standard construction methods, including RAAC (Reinforced Autoclaved Aerated Concrete) planks. NDTScan provides RAAC identification surveys that distinguish RAAC from standard reinforced concrete using GPR, supporting councils and housing associations in meeting their assessment obligations.
Services Available in Oxford
- GPR Concrete Scanning Pre-drill surveys, rebar mapping, post-tensioned cable detection, void detection, slab thickness measurement, and RAAC identification. Same-day attendance available across Oxford and Oxfordshire.
- Ultrasonic Testing of Concrete UPV testing for quality and uniformity assessment, pulse echo for thickness measurement and delamination detection, and SONREB combined method for compressive strength estimation.
- Concrete Compressive Strength Assessment Rebound hammer surveys, UPV combined method, and managed core extraction to BS EN 13791. Independent reporting suitable for engineering acceptance and building control.
Typical Oxford Projects
Oxford-specific work includes: pre-drill scanning in University of Oxford laboratory and teaching buildings; structural surveys for listed building adaptation and heritage refurbishment; GPR surveys of road and bridge infrastructure across Oxfordshire; RAAC surveys in local authority and NHS housing and healthcare stock; and basement pre-drill work in residential properties across North Oxford, Headington, and Summertown.
