Tree Root Investigation & Damage Assessment – Inner West
Our Level 5 arborists conduct professional tree root investigations and root damage assessments across the Inner West, including Leichhardt, Ashfield, and Marrickville.
We locate and map roots affecting buildings, driveways, and underground services using non-destructive AirSpade technology to expose and document roots safely. These investigations help engineers, planners, and homeowners understand root structure, direction, depth, and influence.
In many cases, our findings demonstrate that developments can safely be positioned closer to retained trees when construction methods follow AS 4970 guidelines.
Whether you’re managing cracked paving, foundation movement, or preparing a DA or CDC submission, our reports are accepted by Inner West Council and structural engineers across Sydney.

Frequently Asked Questions
What is a tree root investigation?
It’s a non-destructive process using air pressure to expose roots and map their spread for engineering or Council assessment.
When is a root investigation required?
When damage to foundations or paving is suspected to be caused by trees, or when Council requires proof of root extent before development approval.
Can you confirm if a tree’s roots are causing damage?
Yes, we expose and map root direction, depth, and species to determine the likelihood of structural or paving impact. Our Level 5 arborists provide evidence-based findings recognised by engineers and Council.
Do you install root barriers or provide recommendations?
Yes, we both design and install root barriers. Our arborists specify layout, depth, and materials suited to site conditions, ensuring effective root control while maintaining tree stability and health.
Are your reports accepted by Council and engineers?
Yes, our AS 4970-compliant reports are recognised by Inner West Council and engineering consultants.
