Air Excavation

Air excavation tools use supersonic compressed air to remove soil within the root system of a tree or shrub, with minimal damage when compared to other types of soil removal. Often many tree problems arise from root problems, such as stem girdling roots, raised grade, soil compaction, or trenching.

Air excavation soils can be amended

Decompact soils

Sensitively expose roots for pruning

Trenches installed for utilities within the root system of a tree

Apply nutrient and mycorrhizae directly to the root system

Transplant with intact root systems

Bits and bobs of static cabling systems
Our client did the best they could 1 of 3, cracked maple union
2 of 3 cracked maple union
3 of 3 final bracing install, coupled with cabling system
Drilling for a static cabling system
Brace rod installation, first installed, second hole drilled awaiting installation
Dynamic cables are a good option, supporting natrual biodynamic movement and still provides supplmental support
Installing brace rod
Complex cabling system complementing 6 3/4″ brace rods through a cracked union
A common concern is appearance, here you can see how well they blend into the canopy

Bayview Hall/Cash store. Deletion of parking spaces to releave soil compaction and provide a rooting environment
Farmers market vendors sought this space under the tree, as well as people seeking parking in the shade of the tree
Installed a natural barrier
Often trees are planted too deep. When this happens a secondary root system establishes from the lower trunk. In time the roots expand in diameter along with the trunk. More often than not they constrict the vascular system, and the tree exhibits drought stress symptoms.
Secondary root system girdling tree due to raising grade with topsoil.
The start of a radial trenching/soil amendment job
An exeptionally imbeded girdling root, extreme care had to be taken avoid futher damaging tissues
The site had no other option for their replacement septic system. We mitigated impact to this historic tree, by senstivly cutting roots vs machines breaking and levering roots out.

Cabling/Bracing

Cabling and bracing are a small part of a larger category of supplemental support systems; used to provide support to stems, individual branches, and/or portions of entire trees. Cables, and braces provide supplemental support by limiting the movement of the tree part.

When a tree has a structural defect or a condition that poses a high risk of failure, which may result in injury or property damage, a supplemental support system can often reduce the risk. However, not all potential hazards can be mitigated by an engineered support system.
