NDTScan provides advanced non-destructive testing (NDT) solutions tailored for iml. 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 invests in the most advanced non-destructive testing (NDT) equipment to protect the strength, stability, and safety of timber-based assets and load-bearing wooden structures. Whether we’re inspecting historic buildings, glulam beams, utility poles or critical trees adjacent to infrastructure, we deploy field-proven, high-precision instruments built by IML — the global standard for internal wood structure analysis.
Our IML equipment enables detailed, non-invasive assessment of timber condition, offering critical insight into decay progression, cavity presence, and structural weakening — without compromising the asset’s integrity.
Continuous Innovation in Timber Inspection Equipment
As timber continues to feature in bridges, façades, public realm structures, and engineered construction, accurate internal inspection is vital. NDTScan leads in this space by combining field expertise with the most advanced tools IML offers — ensuring we adapt to varied wood species, section sizes, and risk environments.
Our IML Timber Testing Instruments
- IML RESI PD-Series (PD400, PD500): These resistance drilling systems offer ultra-fine resolution detection of internal decay, rot, and cavity progression in timber structures. Used widely by tree surveyors and civil engineers, the PD series provides precise data at depths up to 500mm with downloadable graphs and USB export.
- IML RESI PowerDrill F-Series: Designed for fast field testing, the F300 and F400 combine drill resistance with lightweight build and integrated graph display. Perfect for heritage timber and overhead structural inspection where minimal intrusion is critical.
- IML Micro Hammer: A simple yet effective tool to assess surface hardness, density gradients, and timber uniformity. Often used in conjunction with PD data for cross-validation on historical timbers and marine piles.
- IML Electronic Measurement Software: All PD-series data is compatible with IML’s integrated software for visual graph analysis and reporting — ideal for insurance claims, structural reports, and council records.
Why We Use IML
IML systems are globally recognised for delivering unrivalled resolution, low operator error rates, and highly repeatable results. Their resistance drillers give us the confidence to diagnose decay with pinpoint accuracy — whether in rail infrastructure, playgrounds, support beams, or protected trees within construction sites.
Alternative and Complementary Tools
In some cases, we also deploy tools like the Fakopp Arborsonic Decay Detector for acoustic tomography, and Argus TreeQinetic for dynamic wind-load simulations. However, IML remains our frontline solution for detailed internal profiling and is trusted across all our timber NDT workflows.
Subsurface Timber Diagnostics with IML Timber Testing UK
At NDTScan, we use IML timber testing UK systems to uncover what lies beneath the surface of wooden structures — without damaging the asset. Whether assessing load-bearing beams in listed buildings, evaluating utility pole condition, or confirming the stability of trees near transport infrastructure, our IML tools deliver precise, data-driven insight into internal timber health.
These systems are indispensable across construction, heritage conservation, landscape management, and civil engineering. They allow our teams to detect rot, fungal decay, insect damage, cracks, and cavities within live wood and installed timber — helping clients make informed decisions on retention, repair, or removal. All without dismantling structures or compromising historical or structural integrity.
Our commitment to non-destructive excellence is matched by IML’s precision hardware, trusted worldwide for its resolution, durability, and data compatibility.
Supporting Safety, Compliance, and Preservation
The structural reliability of timber — whether in architecture or arboriculture — depends not just on surface condition but on what’s happening internally. Undetected voids, fungal progression, or ageing defects can lead to sudden failure with high consequences. IML systems allow us to locate, profile, and measure these risks before they manifest into safety issues.
Our clients include:
-
Local authorities inspecting playgrounds, schools, parks, and civic infrastructure
-
Heritage and conservation consultants working on protected timber frames, floors, or roofing structures
-
Rail and highway contractors managing trees or poles near critical assets
-
Utility providers monitoring wooden poles and supports for electrical and telecom lines
-
Timber frame contractors and developers verifying construction-grade materials during and post-installation
With IML’s high-resolution drilling systems, we detect internal decay at specific depths, track cavity extent, and verify the structural role of timber components in both new and legacy builds.
Field-Ready Instruments for Any Timber Scenario
NDTScan operates a fleet of IML timber testing UK instruments tailored to the varied and unpredictable environments in which timber structures exist.
IML RESI PD-Series (PD400, PD500)
These are our primary resistance drilling systems for deep internal analysis. They deliver continuous drilling profiles at depths of up to 500mm — identifying changes in resistance caused by voids, decay, or compromised density. With USB export and onboard display, the PD series is used on everything from glulam trusses to veteran trees, helping clients visualise internal degradation in seconds.
IML RESI PowerDrill F-Series (F300, F400)
Ideal for fast-response surveys and overhead use, these lightweight drills deliver the same detailed graph outputs as the PD-series but with faster setup and less weight. We frequently use F-series models in overhead beam inspection, elevated poles, and tight-access heritage zones where every gram and minute counts.
IML Micro Hammer
Used to assess surface hardness and density, the Micro Hammer provides fast qualitative data — often used as a secondary check to validate findings from resistance drilling. This is particularly valuable in historic buildings and marine structures, where exposure and layered treatments may impact resistance readings.
IML Electronic Measurement Software
Every resistance profile we collect is backed by IML’s graphing and visualisation software. This allows us to highlight anomalies, tag measurement depths, and attach commentary — forming a complete, interpretable dataset for reports to architects, insurers, or council safety officers. Reports are exportable in multiple formats and can be embedded into larger NDT, condition, or risk assessments.
Helping Clients Make Informed Decisions
Whether we’re scanning a medieval oak roof beam or a roadside ash tree, our role is to deliver accurate, intelligible insight that supports the right decision at the right time. With IML timber testing UK, we offer:
-
Risk classification for decay or cavity severity
-
Recommendations for retention, pruning, reinforcement, or removal
-
Graphical decay profiles for inclusion in engineering and arboricultural reports
-
Scheduled monitoring plans with periodic re-drilling for decay progression analysis
-
Non-destructive heritage surveys that preserve listed structures while meeting compliance
This approach helps clients avoid unnecessary removals, prevent surprise failures, and justify maintenance actions with clear, objective data.
