What Is Tree Root Removal?

Tree root removal is the process of cutting, grinding or excavating tree roots that are causing damage to property infrastructure. This includes roots that have infiltrated pipes, cracked driveways and paths, undermined foundations, displaced retaining walls or are lifting paving and kerbing.

Root removal can range from selective root pruning (cutting specific roots while preserving the tree) to complete root system extraction following tree removal. The approach depends on whether the tree is being retained, the extent of root damage, and what infrastructure needs to be protected.

In many cases, tree root problems are a symptom rather than the cause — trees naturally seek moisture and nutrients, and roots will exploit any crack or gap in pipes, paving or foundations. A qualified arborist can diagnose the root problem and recommend the most effective and cost-efficient solution.

When You Need Tree Root Removal

  • ✓Tree roots have infiltrated sewer, stormwater or water supply pipes causing blockages
  • ✓Roots are cracking or lifting driveways, paths, patios or retaining walls
  • ✓Foundation movement has been attributed to tree root activity by an engineer
  • ✓Roots are damaging pool structures, in-ground plumbing or underground services
  • ✓A tree has been removed but the remaining root system needs to be extracted for construction
  • ✓Surface roots are creating trip hazards across lawns, paths or public areas

How Tree Root Removal Works

1

Root Assessment

An arborist assesses the root problem, identifies which roots are causing damage, and determines the relationship between the root system and the tree’s stability.

2

Solution Planning

Based on the assessment, the arborist recommends the best approach — selective root pruning, root barrier installation, root grinding or complete root extraction.

3

Root Work

The agreed root removal work is carried out using appropriate tools — from hand tools and root saws to stump grinders and excavators for larger jobs.

4

Prevention

Where possible, root barriers or other preventive measures are installed to prevent future root intrusion into the problem area.

Tree Root Removal Cost in Adelaide

Tree root removal costs depend on the extent of root damage, the method required, access conditions and whether the tree is being retained or has already been removed. Selective root pruning is less expensive than complete root system extraction.

If the root problem has caused damage to pipes, foundations or other infrastructure, the total project cost will include both the root removal and the repair work. An arborist can quote on the root removal component; a plumber, engineer or builder handles the repair.

These are indicative prices only. Actual quotes may vary based on your specific requirements, site access and tree condition.

Indicative Price Guide

Selective root pruning$300 – $1,000
Root grinding (surface roots)$200 – $800
Root barrier installation$100 – $200 per metre
Root ball extraction (post-removal)$500 – $3,000
Arborist root assessment report$300 – $600

Tree Root Problems Common in Adelaide

Adelaide’s reactive clay soils in the eastern suburbs and hills areas are particularly susceptible to root-related foundation damage. When large trees extract moisture from clay soils, the soil shrinks and can cause differential settlement of footings and slabs. This is one of the most common causes of foundation cracking in Adelaide.

The city’s older suburbs often have aging terracotta sewer and stormwater pipes that are vulnerable to root infiltration. Species with aggressive root systems — including Eucalyptus, Willow, Poplar and some Fig species — are the most common culprits for pipe intrusion in Adelaide.

Adelaide’s hot, dry summers drive tree roots to seek moisture from any available source, including leaking pipes, irrigated garden beds and areas where soil moisture is concentrated. This natural behaviour can be managed through proper root barriers, appropriate species selection for new plantings and regular pipe maintenance.

If a significant tree (2m+ trunk circumference) is involved, even root pruning may require consideration of the tree’s health and stability. An arborist report may be needed to demonstrate that the proposed root work will not harm or destabilise the tree.

Tree Root Removal FAQs

Yes. In Adelaide’s reactive clay soils, tree roots can cause foundation damage by extracting moisture from the soil, causing it to shrink and settle unevenly. This is known as desiccation damage and is one of the most common causes of cracked walls and uneven floors in Adelaide homes, particularly in the eastern suburbs.
Tree roots in sewer pipes are typically cleared by a plumber using a root cutter or hydro jet. The arborist then addresses the source — either by installing a root barrier to prevent re-infiltration, pruning the offending roots, or in severe cases recommending tree removal. A CCTV pipe inspection is usually recommended to assess the extent of root intrusion.
It depends on how many roots are removed and their significance to the tree. Removing roots on one side of the tree up to the drip line generally will not kill a healthy tree, but may affect its stability. Removing major structural roots or a high percentage of the root system can compromise the tree. An arborist can advise on safe root pruning limits.
A root barrier is a physical barrier (typically high-density polyethylene sheeting) installed vertically in the ground between the tree and the area you want to protect. Root barriers redirect roots downward rather than allowing them to spread horizontally toward pipes, foundations or paving. They are typically installed to a depth of 600mm–1 metre.
Selective root pruning typically costs $300–$1,000, root grinding of surface roots $200–$800, and root barrier installation $100–$200 per metre. Complete root ball extraction (after tree removal) costs $500–$3,000 depending on the size. These are indicative prices only.
If the root problem is localised and the tree is otherwise healthy and valued, selective root pruning with a root barrier may be sufficient. If the root damage is extensive, recurring, or the tree has other issues (disease, structural problems, excessive size), full tree removal followed by root extraction may be the more cost-effective long-term solution.
