ArborSystem
Structural tree pit system supporting urban trees in paved environments
ArborSystem structural tree pit system
ArborSystem is a modular structural tree pit system designed to support pavement loads while creating large volumes of uncompacted soil for healthy urban tree growth.
Specified across streets, public realm and development projects, ArborSystem allows designers to integrate tree planting within paved environments while maintaining the structural performance of surrounding infrastructure.
By separating pavement loads from rootable soil volumes, the system allows trees to establish strong root systems and develop healthy canopy growth.

Growth Beneath
Paved Surfaces
Urban trees require large volumes of uncompacted soil to grow successfully. In paved environments this soil must sit beneath structures designed to support pedestrian and vehicle loads.
ArborSystem provides the structural framework that allows these requirements to coexist, enabling designers to create significant underground soil volumes while maintaining pavement performance.
Supports healthy root development beneath hard surfaces
Creates structural separation between pavements and soil volumes
Allows significant underground rooting space within constrained sites
Designed for integration within urban streets and public realm schemes
Compatible with surrounding paving and infrastructure systems
Supports long-term canopy establishment in paved environments
Key Characteristics
ArborSystem is designed to work within the realities of urban construction. Its modular layout adapts to varying site constraints while supporting practical installation, utility coordination and reliable structural performance beneath paved surfaces.
Benefits of ArborSystem
ArborSystem is designed to support both practical delivery and long-term tree growth performance. From installation access through to utility coordination, the system helps create buildable tree pit infrastructure within complex urban environments.

Integrating ArborFlow
ArborSystem can also form the structural foundation of ArborFlow, GreenBlue Urban’s SuDS tree pit system.
With the addition of drainage components and hydraulic control layers, ArborSystem structures can contribute to sustainable drainage strategies within streets, public realm and development environments.
This allows tree pits to support both healthy tree growth and stormwater management within integrated urban infrastructure schemes.
By combining structural support, rootable soil volumes and water management within a single coordinated system, ArborFlow helps maximise the value of urban tree planting within constrained sites.
