The TreeParker® Cell System is a cutting-edge underground structural soil cell solution, engineered to create optimal growing conditions for urban trees while supporting heavy vehicular traffic above. Designed with input from landscape architects, contractors, and local authorities, TreeParker® enables large, healthy trees to thrive beneath roads, pavements, car parks, and plazas—without compromising surface stability or tree health.

This modular, high-strength geocellular system offers up to 95% soil volume, maximising space for unimpeded root development while withstanding vertical loads of up to 550 kPa. TreeParker® also promotes stormwater infiltration, making it an ideal component of SuDS (Sustainable Drainage Systems) strategies.

Available in multiple depths ranging from 40cm to 150cm, the system provides flexible, utility-friendly installation—ideal for retrofits and complex urban projects.

High Soil Volume – Up to 95% of the system is filled with uncompacted, high-quality soil.
Traffic-Load Tested – Load-rated to withstand up to 550 kPa, suitable for HGVs.
Modular & Scalable – Easy to install, extend or reconfigure around utilities.
Curved Layout Ready – Can be installed in arcs down to a 5m radius.
Unrestricted Root Growth – Large spacing between legs promotes healthy tree root expansion.
Stormwater Management – Up to 25% void for water infiltration and SuDS compliance.
No Pavement Lifting – Soil settlement and expansion within the system won’t impact surface finishes.
Utility Friendly – Freestanding, non-interconnected units can be manoeuvred around existing services.
Maintenance-Ready – Units can be opened and closed without compromising system integrity.
Adjustable Heights – Available from 40cm to 150cm to suit site constraints and maximise soil volume.
Chemically Inert – Inert plastic components with a 100-year guarantee in soil contact.
Sustainable Design – Made from long-life, 100% recyclable materials.
