Resistograph Testing for Tree Decay
If your Local Authority, Tree Consultant or Tree Surgeon has requested further in-depth information regarding the condition of your trees, Arbor Cultural can help. We’ve invested in the technology you need. We can provide high-level Resistograph decay detection, courtesy of our IML RESI-PD400 instrument.
How is this important, and what does it mean?
Well, sometimes, knowing what’s going on inside a tree is impossible. It looks fine, but appearances may be deceptive. Problems can lie inside, undetected, so we need precision, care and versatility all rolled together into one piece of equipment.
We identify hollow sounding areas for further investigation by assessing the trees with a nylon hammer.
A State-Of-The-Art Strength Measurement Tool For Trees
Resistograph decay detection is a non-destructive way to analyse the resistance of wood to drilling and the amount of pushing force and rotating force needed to penetrate a tree stem. Different decay processes weaken the wooden in different ways, which is why both tests are important.
This sophisticated piece of kit accurately measures how much strength a tree’s stem or branch has (or hasn’t) lost. In short, it accurately gauges the relative density of wood. Therefore, it can help us decide on your behalf, whether you can retain it or may need to consider a form of tree surgery.
Or, furnish your local council with extra data for your planning approval.
Both these readings – the resistance of the wood to drilling and its pushing force – are displayed in a digital readout on the device, which we can export as a graphical image into a report. The RESI will find the exact location and type of decay within the wood.
It will also help over time to determine the type, extent of progress of decay, by undertaking periodic repeat assessments.
If we do find fungal decay or rot, we can undertake further non-destructive tests to assess the extent of the damage. And, to determine if the tree could become unstable without intervention.
Knowing what’s happening internally to your tree could help avoid legal action and, of course, keep people and nearby property much safer.
Resistograph Testing for Wood Decay: Nurturing Nature
There’s no need for concern: during the process, trees will experience minimal damage. The IML RESI-PD400 is only 3mm in diameter and 400mm long.
In our opinion, this is streamlined work at its absolute finest – fully respecting the age and dignity of nature. Yet, leading-edge, with powerful results. “Do no harm” applies to the world around us, and this is an excellent example of this concept in action. This minimally invasive technique helps to preserve both ancient and modern trees and helps to keep our environment green.
