IML Equipment NDT Solutions

Overview

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, reliable 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 careful 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 confidence, 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 careful, 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 reliable, 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.

Proven Across the UK’s Built and Natural Environment

NDTScan’s IML timber testing UK systems are in daily use across:

Timber-framed buildings: Validating tie beams, posts, joists, purlins, and king post trusses
Public trees and street trees: Supporting BS5837 assessments, risk zones near infrastructure, and ongoing condition audits
Bridges and timber decks: Verifying bearing integrity in pedestrian, cycle, and rural structures
Marine and waterside installations: Evaluating pile condition, decking timbers, and wetland boardwalks
Playgrounds and parks: Scanning poles, features, and fences for structural decay and safety compliance

From ancient oak to modern engineered timber, our IML systems deliver the same clarity and repeatability, backed by a full reporting process and, when needed, multi-tool verification.
