Soil Cell Systems for Urban Trees

Create protected volumes of uncompacted soil beneath sidewalks and paved areas, giving urban trees the rooting space needed for healthy, long-term growth.

The Challenge Below Ground

In municipal streetscapes, tree roots compete for space with sidewalks, utilities and compacted soils. Restricted rooting volume and poor movement of water and air can limit establishment. Successful tree planting starts with designing the below-ground environment around the needs of mature trees.

Compacted soil restricts root development

Mature trees need adequate rooting volume

Roots and utilities require coordinated space

Water and oxygen must reach the root zone

How Soil Cells Support Tree Growth

Soil cells separate structural support for paved surfaces from the growing medium below, creating protected volumes of uncompacted soil for roots. This approach gives project teams control over soil volume, aeration and root development while maintaining the structural performance required in busy urban environments.

Supports paved surfaces while protecting soil below

Keeps rooting soil uncompacted and accessible

Allows water and oxygen to move through the root zone

RootSpace

Modular Soil Cell System

RootSpace creates volumes of uncompacted rooting soil beneath paved surfaces while supporting structural loads.

RootSpace® provides a modular structural framework that supports sidewalks and other paved areas above while protecting uncompacted soil for root growth below. Its open design maximizes usable soil volume and can be coordinated with other tree pit components, helping create the below-ground conditions needed for healthy urban trees.

RootCell

Compact Root Chamber System

RootCell® is the original compact modular root chamber system, ideal for applications where a smaller soil cell format is appropriate. Our technical team can advise whether RootCell or another soil cell solution best fits the site requirements.
