What are Root Barriers Used for?
Tree roots, depending on the species, can be extremely invasive. They can cause underground damage including property foundations; telecommunication wires; pipes and utilities. They can also push up pavements and driveways causing trip hazards. Root Barrier Installation is an excellent method to prevent tree roots from spreading to a problematic area.
Healthy Root Growth:
Most problems with trees can be traced back to poor root growth. This is typically the result of disturbed, damaged or compacted soil conditions. We employ various techniques to improve the soil profile in the root zone. This encourages healthier root growth and therefore healthier trees.
Tree Protection Zone:
A root barrier installation should always be overseen by an experienced and qualified arborist who understands tree biology and growth patterns. They will know the best position to insert the root barrier and how to protect the roots so that the tree remains healthy. The trench must always be dug outside of the Structural Root Zone (SRZ) to protect the tree and within the Tree Protection Zone (TPZ). The calculations to ascertain the protection zones are based on the Australian Standard AS4970-2009 Protection of Trees on Development sites.
How it works:
The Arborist will locate the tree roots by using the perimeter of the tree’s canopy as a guide. Using a Vacuum Excavation wand (a high-powered hose) to remove soil and clay, the tree roots will be exposed. A root barrier trench can either be dug out in a semi-circle around the tree or in a straight line alongside a fence line for example. Generally, a trench is 900 mm deep and 100mm wide but can be dug to any size requirements. Once the tree roots have been located the soft wand is used to expose the roots while keeping the Cambium layer (skin) intact as this will protect them. If the cambium layer is removed the tree roots will die thus great harming the tree’s chances of survival.
Once the tree roots are exposed and the trench is dug, the tree roots are cut and a natural honey solution is used to treat the ends of the cut roots. The honey seals the cut root ends and reduces the risk of fungus and pests. A specially designed root barrier material can then be positioned within the trench. Next a layer of Bentonite (greyish, white granules which hardens into a clay substance which tree roots will not penetrate) is poured onto the trench, followed by a layer of soil and then another layer of Bentonite. Finally, the root barrier is back filled with garden soil and it should be unnoticeable that a root barrier is in place.
