Tree Protection Zone
APC recently completed a tree protection zone paving project designed to protect established root systems while meeting Australian standards. We installed permeable concrete around the base of mature trees so water, air and nutrients keep reaching the roots, supporting healthy growth without undermining nearby paths or infrastructure.
What is a tree protection zone?
A Tree Protection Zone (TPZ) is the area around a tree's base that needs to be safeguarded during construction or landscaping work. Getting the paving right in this zone matters: standard concrete seals the soil and starves roots of water and oxygen, while tree protection zone paving lets both keep reaching the root system below, without compromising nearby infrastructure.
Why choose APC for tree protection zone paving
Our Permcon technology is built for exactly this job. It's permeable enough to let water, air and nutrients reach tree roots in built-up areas, but strong enough to carry foot traffic and sit alongside footpaths and other infrastructure without shifting or cracking.
On this project, that meant:
- Permeable concrete surfacing that complies with the Australian standard for tree protection zones
- A finish that ties in visually with the surrounding landscape
- A durable surface that's built to last as the tree matures, rather than needing replacement
Working this way isn't just about ticking a compliance box. It's a genuinely more sustainable approach to urban greenery, one that lets councils and developers protect established trees on site instead of removing them, while still handing back a surface people can actually use.
Choosing APC for tree protection zone paving means choosing a team that's done the research on how permeable concrete behaves around root systems, not just how it looks once it's poured. That's the difference between a surface that protects a tree for a season and one that supports it for decades.
