NDTScan provides advanced non-destructive testing (NDT) solutions tailored for archaeology and cultural heritage. Our services ensure accurate, compliant, and efficient diagnostics across all sectors, from aerospace to infrastructure. With cutting-edge equipment and over a decade of experience, we deliver certified inspections that minimise downtime and maximise safety. Trust NDTScan for reliable, data-driven reporting that enhances your decision-making and operational excellence.
NDTScan protects irreplaceable archaeological sites, historic structures, and cultural heritage assets using advanced non-destructive testing (NDT) techniques. From ancient masonry to buried features, we reveal hidden construction methods, material conditions, and structural vulnerabilities without disturbance or damage.
Our Archaeology and Cultural Heritage work is sensitive and vital. We detect internal voids, cracks, moisture ingress, and early-stage degradation that threaten the longevity of artefacts, monuments, and historic buildings. Using ground penetrating radar (GPR), ultrasonic pulse velocity testing, resistivity imaging, and thermal scanning, we deliver detailed insights into structures above and below ground.
We don’t just scan—we preserve history, support conservation decisions, and help archaeologists, conservation architects, and Archaeology and Cultural Heritage organisations protect legacy assets for future generations.
Revealing the Hidden Stories Beneath Our Feet
Historic sites often hide unseen construction details, hidden chambers, and areas of weakness masked by centuries of use and repair. Modern NDT techniques uncover these without intrusive excavation or material removal, providing data essential for accurate conservation and restoration planning.
NDTScan leads the way in heritage-focused scanning services. Our techniques provide verifiable evidence of internal conditions, original construction methods, hidden features, and damage patterns—all essential for maintaining structural integrity and historical accuracy. We empower custodians of cultural heritage to act with precision and respect.
How We Survey Archaeological and Cultural Heritage Assets
Every historic site presents unique challenges. Our tailored survey methodologies adapt to ruins, castles, churches, subterranean chambers, ancient foundations, listed buildings, and monuments. All equipment is lightweight, portable, and operates without vibration, minimising risk to fragile structures.
We work closely with Archaeology and Cultural Heritage conservation teams, archaeologists, heritage officers, and building surveyors to schedule scans around site access constraints, visitor hours, and environmental protections. Reporting is rapid, typically including 2D and 3D visualisations, CAD overlays, and annotated condition assessments.
Our heritage survey techniques include:
- Ground Penetrating Radar (GPR): Maps subsurface features, voids, and construction layers without excavation.
- Ultrasonic Pulse Velocity (UPV): Assesses internal cohesion and identifies cracks or deterioration in stone and concrete.
- Electrical Resistivity Imaging (ERI): Visualises moisture ingress, voids, and buried structures below ground level.
- Thermal Imaging: Detects moisture intrusion, hidden construction features, and areas of thermal inefficiency.
- Drone Photogrammetry: Captures detailed high-resolution imagery of large or inaccessible historic structures.
- Pushrod and Telescopic Camera Surveys: Inspects voids, wells, and internal spaces with minimal access points.

Our non-destructive testing services allow heritage custodians to investigate safely, plan confidently, and act responsibly — ensuring that archaeological and cultural heritage resources endure for future generations.
Non-Destructive Archaeology and Cultural Heritage Insight into Fragile Historic Structures
Historic buildings and archaeological sites are often fragile, undocumented, or at risk from environmental and structural stresses. NDTScan provides deep diagnostic clarity across:
-
Listed and scheduled buildings
-
Cathedrals, abbeys, and places of worship
-
Archaeological excavation zones
-
Burial chambers, crypts, and subterranean voids
-
Dry-stone walls, ancient fortifications, and earthworks
-
Decorative elements including mosaics, frescoes, and carved façades
Our equipment is carefully selected for low-vibration, low-contact operation. This ensures all surveys comply with conservation principles while offering accurate, actionable data to conservation architects, archaeologists, and heritage engineers.
Archaeological and Cultural Heritage Survey Techniques
Each archaeological and cultural heritage site requires a bespoke inspection strategy. NDTScan applies the following non-invasive techniques:
Ground Penetrating Radar (GPR)
GPR is ideal for scanning beneath floors, courtyards, or open ground. It maps subsurface anomalies, buried foundations, voids, and previous occupation layers without any excavation. In archaeological settings, this technique often reveals previously unrecorded features such as walls, roads, or ritual structures.
Ultrasonic Pulse Velocity (UPV)
Used to assess material homogeneity, crack development, and internal deterioration in historic stone, concrete, or masonry. This method is key in identifying delamination and internal fracturing, especially in load-bearing Archaeology and Cultural Heritage structures or façades.
Electrical Resistivity Imaging (ERI)
This technique measures how electrical current moves through the ground or structure, highlighting moisture ingress, decay, buried features, or soil instability. ERI is a valuable tool for archaeological interpretation and environmental risk assessment in heritage settings.
Thermographic Archaeology and Cultural Heritage Imaging
Thermal scanning detects moisture paths, air leaks, and subsurface voids by observing temperature variations. It is non-contact and non-invasive — making it particularly useful for inspecting ancient walls, floors, and conservation-sensitive surfaces.
Drone-Based Archaeology and Cultural Heritage Photogrammetry
For elevated, delicate, or large-scale heritage sites, drones capture high-resolution orthophotos and 3D models that support condition monitoring, digital archiving, and planning applications. This is often deployed for castles, church towers, monuments, and remote archaeological landscapes.
Remote Camera Systems
Our pushrod and telescopic cameras access wells, ducts, voids, and cellars that are otherwise inaccessible. These systems provide real-time visuals and still images that support internal mapping and safety reviews.
Safeguarding the Past with Digital Precision
NDTScan provides more than Archaeology and Cultural Heritage data — we deliver conservation-ready documentation aligned with Historic England, CADW, and ICOMOS guidelines. Our outputs help inform:
-
Heritage impact assessments
-
Scheduled monument consent applications
-
Conservation management plans (CMPs)
-
Structural intervention designs
-
Restoration and grant funding submissions
-
