Decay is a natural tree ageing process and commonly occurs in trees without necessarily causing structural weakness. However, advanced decay can be a major concern in relation to human safety and damage to property.
Some decay can progress and eventually weaken stems, branches and roots, resulting in mechanical failure.
We evaluate the tree to determine the extent of the decay so that informed management decisions can be made.
This will ensure that hazardous trees are correctly identified and relatively safe trees are not removed or unsuitably pruned.
The Picus Sonic Tomograph is a sophisticated ultra sound measuring tool that detects the amount of decay in a cross section of a tree.
The tree can be tested at several levels to build up a map of the extent of the decay or structural fault.
The results of the Picus assessment can be verified by resistance microdrill tests to determine the quality of the wood within the residual wall.
Once the extent of the decay has been assessed, remedial action can be prescribed to limit the risk of structural failure using the latest analytical software.
