Structural Tree Pit Supply & Installation
At Modern Environments, we specialise in the supply and installation of structural tree pits for commercial, council, and infrastructure projects across greater Auckland. Our systems ensure that trees thrive in urban environments while pavements, roads, and surrounding infrastructure remain safe and intact.
Why Structural Tree Pits?
Structural tree pits are engineered systems that provide the soil volume and stability trees need to establish healthy root networks — without compromising the surrounding built environment.
- Support healthy root growth: Preventing soil and root compaction and allowing long-term canopy development.
- Protect pavements and services: Reducing the risk of cracked surfaces, displaced kerbs, and damaged utilities.
- Integrate stormwater management: Enhancing water infiltration and reducing runoff burden on local drainage networks.
- Extend tree life expectancy: Creating the right balance of soil, air, and water for long-term resilience.
Our Structural Tree Pit Solutions
Modern Environments partners with leading global suppliers to deliver proven systems that perform in New Zealand’s urban conditions:
1. ACO Blue-Green Infrastructure Systems
ACO systems combine structural strength with sustainable stormwater management. Designed for urban resilience, they help filter and capture water while supporting trees in hard-surface environments.
2. Citygreen StrataCell Soil Vaults
The Citygreen StrataCell is one of the world’s strongest modular soil cell systems. It delivers uncompacted soil volume beneath paved areas, ensuring trees flourish while surfaces remain structurally sound under heavy loads.
By offering both ACO and StrataCell systems, we match the right solution to your project’s requirements — from high-traffic CBD streets to large-scale commercial developments.

FAQs
Think of it like giant lego where large plastic structures click together to provide a solid structure. Pavements get built over the tree pits while soil and tree roots happily occupy the voids in this underground lego.
The stormwater restocks the soil moisture throughout the structural tree pit. Absorbs water as it arrives and stores it for the tree to consume on dry days. As a consequence, many hundreds of litres are stored before any surplus gets to the drainage pipes at the bottom of the tree pit. It slows the whole process of stormwater runoff.
There are several in the market, but at Modern Environments, we find Aco and City Green are leaders at present.
It depends on size, but think in terms of several thousand dollars. For a city tree whose life will well exceed that of the children that climb it is a minor cost for beautiful green infrastructure
