Advanced Decay Detection

See What’s Hidden Inside Your Trees

PiCUS Sonic Tomography
A non-invasive imaging technique that maps internal decay by measuring sound wave velocity through the wood. Ideal for veteran trees, high-value specimens, and trees in sensitive locations.

Resistograph Microdrilling
A precision tool that records drilling resistance to detect cavities, cracks, and decay columns. Provides quantitative data on wood density and structural loss.

Integrated Decay Reports
Clear, illustrated reports combining PiCUS and Resistograph data with expert interpretation. Includes risk implications, management recommendations, and retention strategies.

Support for Planning, Safety & Conservation
Whether you’re managing a heritage tree, assessing a roadside specimen, or supporting a planning application, our decay detection services provide the evidence you need.

Air Spade Investigations

Our decay detection service utilises Air Spade technology to carefully expose root systems for detailed examination of decay, fungal infection, and overall root health. This method enables accurate identification of compromised roots that may affect tree stability and vitality. 

Through thorough root condition assessments, we provide actionable recommendations for tree management and risk mitigation, supporting the preservation of tree health and safety in both urban and development contexts. 

The Air Spade is used as a non-invasive system because it employs compressed air to gently remove soil from around tree roots without causing physical damage. Unlike traditional excavation methods that can sever roots and harm tree health, the Air Spade preserves the integrity of the root system while allowing detailed inspection. This approach minimizes disturbance to the tree and surrounding environment, making it ideal for sensitive sites where tree preservation is critical. Its precision and safety make it a preferred choice for root investigations in both development and arboricultural contexts.
