NDTScan provides advanced inspection of trees and structural timber using high-precision tools from Sylva — a trusted manufacturer of dynamic tree stability testing and arboricultural risk assessment equipment. These systems are essential when evaluating the safety of trees near highways, railways, schools, public parks, and construction zones where tree failure could pose serious hazards.
Our Sylva systems support non-invasive diagnostics, combining motion analysis and resistance testing to provide objective, measurable insights into root plate stability, trunk integrity, and wind-load response.
Continuous Innovation in Tree Risk Assessment
Trees are vital to urban infrastructure but require careful management. As climate events and extreme weather increase, the risk of sudden tree collapse grows. We invest in proven, repeatable technologies that allow our team to quantify tree stability under realistic conditions — supporting arborists, engineers, and safety professionals with evidence-based decision-making.
Our Sylva Tree Inspection Equipment
- Sylvatest Duo: A precision system that measures wood density and elasticity in standing trees and structural timber. Used to assess internal soundness without the need for coring or invasive drilling.
- TreeQinetic Static Pulling Test System: Assesses tree anchorage strength and root plate movement by simulating wind-loading conditions. Delivers calibrated data on whether a tree is likely to fail under stress — essential for councils and rail infrastructure operators.
- Sylva Resistograph Integration: When paired with resistance drills such as IML PD400, Sylva systems help verify findings with both motion-based and penetration-based metrics.
- Wireless Motion Sensors: High-sensitivity accelerometers that detect trunk oscillation, allowing for remote or wind-based testing. Data is logged and reviewed over time to monitor changes in condition.
- Sylva Software Platform: All data is collected and visualised in a streamlined dashboard for reporting, trend analysis, and third-party review — enabling defensible decisions in tree removal or retention cases.
Why We Use Sylva
We chose Sylva because of its field reliability, repeatable data output, and acceptance across arboricultural consultancy, local authority planning, and insurance sectors. When safety-critical trees border footpaths, rail lines, or development sites, we use Sylva to deliver clear go/no-go assessments that stand up to scrutiny.
Alternative Tools Considered
Where additional internal detail is required, we may also use Fakopp Arborsonic for decay tomography or IML resistance drills for core profiling. However, Sylva remains our core platform for wind-stability testing and movement-based diagnostics due to its scalability, speed, and minimal impact on the tree being assessed.
Advanced Timber and Tree Inspection for Safety-Critical Environments
At NDTScan, our inspection services don’t stop at steel and concrete. We bring the same level of precision and engineering rigour to the assessment of mature trees and structural timber, helping clients manage natural assets where failure could have serious safety or financial consequences.
From decayed oak limbs overhanging schools to mature roadside trees exposed to increasing storm intensity, we deliver evidence-led diagnostics that go far beyond visual inspections or subjective assessments. Our approach ensures councils, developers, insurers, and facilities managers can make informed decisions on tree retention, removal, or remediation.
The Need for Precision in Tree Risk Assessment
Tree failure is often sudden, and without adequate inspection, the consequences can be severe—blocking roads, damaging buildings, injuring the public, or disrupting rail and energy infrastructure. Traditional arboricultural surveys, while useful, are limited when it comes to hidden decay or underground root issues.
Our advanced testing platform allows us to go deeper—quite literally. By simulating wind load, measuring oscillation, and detecting changes in trunk and rootplate behaviour, we assess not just condition, but mechanical stability. This is essential when determining whether a tree is structurally sound enough to remain in place under likely environmental stress.
How We Assess Tree Stability
Each tree has unique characteristics—species, age, health status, and site exposure all play a part. That’s why our team uses a combination of diagnostic methods to provide a multi-layered picture of structural soundness:
-
Motion Analysis: High-resolution sensors are mounted on the trunk to measure sway and oscillation patterns. These readings help quantify how a tree behaves in wind, and whether movement suggests compromised anchorage or a decayed core.
-
Pull Testing: When more definitive answers are needed, we apply controlled static loads to the tree using winches and cables, while monitoring root plate movement and trunk tilt in real-time. This simulates storm conditions in a safe and measurable way, providing calibrated data on failure thresholds.
-
Resistance Testing: Where there’s suspicion of internal rot or voids, precision drills can be used to measure resistance along the grain of the wood. The results confirm internal condition without removing large cores or compromising the tree’s vitality.
-
Timber Structure Inspection: For buildings, bridges, or heritage assets constructed with timber, we assess beams, joists, and uprights using similar density and elasticity measurements. We identify hidden decay, fungal breakdown, or overloading before visible failure occurs.
Applications Across Multiple Sectors
Our tree and timber inspection services are trusted by a wide range of clients where public safety, liability, or asset value is on the line:
-
Highways and Transport Authorities: Trees lining major roads, railways, and pedestrian walkways are a well-known hazard during storms or high winds. We assess their stability using controlled pull tests and wind-load simulations, helping reduce emergency removals and unplanned closures.
-
Construction and Development Sites: Mature trees often surround new builds, especially in green belt zones. We provide formal assessments that support planning decisions, tree preservation order (TPO) compliance, and risk management during earthworks or excavation.
-
Public Parks, Schools, and Care Facilities: Safety around vulnerable people is paramount. We evaluate trees in areas where children, the elderly, or large groups gather, helping site managers make decisions that balance ecology with duty of care.
-
Utilities and Critical Infrastructure: Transmission corridors and substations must remain clear and operational. We inspect nearby trees and timber supports to prevent encroachment, contact risks, or collapse.
-
Heritage Sites and Conservation Projects: Historic timber-framed buildings or protected woodland environments require a sensitive, low-impact approach. Our tools are non-invasive, leaving no damage or scarring.
Why Our Approach Is Trusted
We don’t rely on assumptions or subjective scoring systems. Every inspection we perform is backed by quantifiable data. Results can be plotted over time to monitor deterioration, or benchmarked against failure thresholds defined by structural arboriculture research and engineering standards.
Our systems are calibrated, repeatable, and portable—allowing us to inspect single trees or entire estates with equal efficiency. Reports are formatted for easy review, whether by local authority officers, insurance assessors, or structural engineers. In contentious or public-facing situations, having empirical data on file can be critical.
Reporting and Compliance
We understand that many clients operate under tight compliance regimes. Whether it’s in accordance with BS 5837:2012, arboricultural method statements, or insurance risk frameworks, our reporting is designed to support defensible action. We include test methodology, calibration references, photographic evidence, GPS tagging, and clear recommendations based on risk levels.
Where appropriate, we also integrate findings into broader asset management platforms, ensuring tree health and timber safety can be managed as part of an overall risk profile—not as isolated or reactive tasks.
Looking Ahead: Climate Impact and Urban Tree Risk
With increasing urbanisation and more extreme weather events, trees are under pressure. Prolonged droughts, higher wind loads, and compacted soils are reducing root strength and increasing failure rates. As a result, tree risk assessment is becoming more vital and more technical.
NDTScan is actively evolving its service offering to meet these emerging challenges. We’re integrating remote monitoring for long-term analysis, developing AI-assisted interpretation of sway data, and trialling drone-based canopy analysis for inaccessible trees.
Our goal is to enable smarter, proactive management—not just reactive removals after damage has already occurred.
