Frequently Asked Questions
When is tree root investigation required?
Tree root investigation is required when development occurs close to trees or where roots may impact structures. Root mapping is commonly required for DA and CDC proposals, driveways, retaining walls and structural damage assessments.
How do you map tree roots?
We use non-destructive methods including AirSpade excavation, soil windows and surface tracing. AirSpade technology safely exposes roots, allowing accurate measurement and scaled mapping.
Do you map TPZ and SRZ areas for architects and engineers?
Yes. TPZ and SRZ plans are included in all root investigation reports. We overlay mapped roots and protection zones directly onto architectural drawings for compliance.
Can root investigation prevent costly redesigns?
Yes. Early root mapping identifies potential conflicts before construction begins, helping designers and builders adjust methods and avoid redesign delays.
