Are you concerned about the safety of a tree? Whether you need to satisfy an insurance requirement or fulfill your legal duty of care, we provide the certainty you need. Using Arbotom Sonic Tomography and Resistograph technology, we assess structural risks without the guesswork.

We undertake sonic tomography on trees—a highly advanced diagnostic process akin to a medical ultrasound. Sensors are placed strategically around the circumference of the tree to measure the time sound waves take to travel through the timber.
This collected acoustic data is simultaneously transmitted to our diagnostic computer, creating a coloured 2D or 3D image. The software meticulously maps zones of differing sound-transmission properties, clearly highlighting hollow spots, degradation, and internal decay without destructive impact.

A tree’s ability to resist decay organisms depends entirely on its root system. In urban areas like London and Surrey, severely compacted soil often prevents roots from accessing the water and oxygen they desperately need to survive.
We utilize an Air Spade (Compressed Air Lance) to blast apart compacted soil without causing any damage to delicate fibrous roots. This technology allows us to safely inspect structural roots for decay without the destruction caused by mechanical digging.

For detailed, physical confirmation, we utilize the brand new IML RESI-PD400 micro-drill. This specialist instrument, a form of Resistograph, measures both torsional resistance and the pushing force required to penetrate the tree stem.
Both readings are displayed on a digital readout and exported as detailed graphical images directly into your safety report, offering a level of precision that visual inspections simply cannot match. This allows us to definitively quantify strength loss in high-stakes risk assessments.

Structural integrity is only part of the story. We utilize Arbor Check chlorophyll fluorescence testers to measure a tree’s physiological vitality and stress levels.
By understanding the tree's internal energy reserves, we can design management specifications—such as targeted minor weight reduction—that manage the safety risk effectively without triggering a spiral of decline that often follows heavy pruning or traditional "topping."
Find Out MoreTraditionally, trees exhibiting decay were heavily reduced or "topped" to reduce wind loading. While this reduces dynamic load, it often destroys the tree’s physiological health.
Removing the leaf area cuts off the energy supply (sugars) the tree requires to fight the fungal pathogen. This triggers a "spiral of decline" where the tree becomes too weak to stop the decay from spreading.
Our approach utilizes diagnostic data to design management plans that keep trees safe without compromising their biological health.
By identifying the exact residual wall thickness and identifying the specific fungal pathogen, we can recommend minor, targeted weight reductions that preserve the tree's energy reserves and long-term vitality.
