Root Investigations With Air Spade Excavation

A root investigation may be necessary for various reasons, such as assessing potential damage caused by tree roots to structures or determining the extent of root systems during development projects.

We utilise a specialised compressed air excavation tool called an Air Spade for root investigations. This device allows for fast and safe excavation around tree roots, quickly and carefully moving soil while preserving the integrity of the roots and any underground services. The Air Spade method enables us to uncover offending roots and assess the situation before selective root removal, crucial for maintaining the tree’s stability.

When excavating near driveways or slabs, the Air Spade ensures that underground services remain unaffected. We can locate and remove destructive roots and, if necessary, install a root deflecting membrane or barrier to guide roots away from structures. This approach allows for tree retention while protecting the integrity of the structure. In many instances, the cost of these measures is lower than that of tree removal.

Frequently Asked Questions

A root investigation is an assessment to determine the extent and impact of tree roots on structures or to understand the root system’s layout, especially during development projects. It helps identify potential issues and guide appropriate management strategies.

A root investigation may be necessary to:

Assess potential damage to structures caused by tree roots.

Determine the extent of root systems during development or construction projects.

Plan for root management to prevent damage while preserving the tree’s health.

An Air Spade is a specialised tool that uses compressed air to excavate soil around tree roots. It allows for fast and safe excavation, minimising damage to roots and underground services.

The Air Spade works by directing a high-pressure stream of compressed air to move soil away from tree roots. This method preserves the roots and any nearby underground services while revealing the root system for further assessment or management.

The Air Spade provides several benefits:

Safe Excavation

It carefully removes soil without damaging roots or underground services.

Efficiency

It speeds up the excavation process compared to traditional methods.

Precision

It allows for accurate assessment of root systems and identification of problematic roots.

Yes, if necessary, we can install root-deflecting membranes or barriers during the investigation. These installations help direct roots away from structures and prevent future damage.

Managing roots can preserve the tree’s health and stability, which often contributes to the overall aesthetic and ecological value of the area. It is generally a more cost-effective solution compared to tree removal and allows for continued enjoyment of the tree’s benefits.

In many cases, the cost of root management measures, such as using an Air Spade and installing root barriers, is lower than the cost of tree removal. Additionally, preserving the tree can offer long-term benefits and savings.

The duration of a root investigation depends on the complexity of the root system and the size of the
area being examined. Generally, using an Air Spade makes the process quicker and more efficient
compared to traditional excavation methods.
