Non-Destructive Root Investigation (NDRI) – Melbourne

At Arborplan Arboriculture Consultants, we use Non-Destructive Root Investigation (NDRI) to safely and accurately locate and assess tree roots without causing harm to the tree or surrounding soil.

This method is essential for construction and development projects where trees are intended to be preserved but may be impacted by excavation, trenching, or other works.

Why Root Investigation is Important

Tree roots are often overlooked during construction planning – but damaging them can seriously affect tree health, stability, and safety.
In severe cases, root damage can lead to tree decline or even removal.
An NDRI ensures you have accurate information before work begins, helping you protect valuable trees and remain compliant with council requirements.

Our root investigations determine:

  • Presence of roots in the proposed work area

  • Number and size of roots found

  • Depth and spread of root systems

  • Potential impact of construction on tree health and stability

This information helps us understand how the tree may respond to your proposed works – and whether design adjustments are needed to keep it healthy.

How We Work

  1. On-Site Investigation – Using specialised non-invasive tools, we expose and inspect the roots without damaging them.

  1. Data Collection – Measurements, root mapping, and photographs are recorded for accuracy.
