Integrated tree planting systems for streets and landscapes

Urban trees for cooler, cleaner, greener cities

Tree pit systems for better rooting, aeration and irrigation; help urban trees thrive, help communities prosper.

How to ensure trees thrive

Urban trees need uncompacted soil, oxygen and water for optimal growth – and protection for both roots and surrounding surfaces. Our systems are engineered around these needs and aligned with FLL/ZTV standards: structural soil cells for rooting and load, irrigation/aeration, root management and protection, all designed as one modular, integrated approach – with sustainability built in through recycled and recyclable materials.

What we deliver

Our tree planting systems have been developed and refined over decades of research and project experience, underpinned by independent testing. Each component is designed to support tree health while protecting surrounding assets – delivering resilient urban planting that meets modern compliance standards.

Every solution is part of a modular system, making it easier to specify, approve and deliver — whether for trafficable city streets or soft landscape environments.

Tree establishment support – Irrigation and aeration to the root zone for stronger, faster establishment.
Protected assets – Root guidance and barriers to prevent heave, safeguard utilities and extend pavement life.
Load-ready pits – Soil cells engineered for high strength and stability, FLL/ZTV-Vegtra-Mü compliant, with independently verified test data
SuDS-ready components – Integrated inlets, liners and chambers to detain, filter and release water sustainably at source.
Sustainable by design – RootSpace soil cells manufactured from 100% recycled polypropylene, fully recyclable at end of life, with Environmental Product Declaration (BRE EPD) for transparent lifecycle performance.

ArborSystem

Engineered tree-pit systems for streets and squares.

Other soil cell options

While ArborSystem is built around RootSpace – our most advanced soil cell – GreenBlue Urban also supplies StrataCell and RootCell. These earlier-generation structural cells remain available for projects with specific requirements or legacy specifications.

ArborScape

Tree planting support for verges, parks and open landscapes.

ArborFlow

Surface-water management through tree planting.
