RootBox Modular Units

The RootBox is essential for urban tree-planting because it provides a controlled environment that supports healthy root development and growth while preventing damage to surrounding infrastructure, sidewalks and utilities.

The RootBox systems, manufactured by HTW – TreeRoot Systems are durable, modular, soil-cell systems that can be easily assembled at any desired site. The components can be pieced together in a structural matrix, forming a spacious (approx. 95%) sub-pavement unobstructed skeleton. The absence of horizontal bars enables homogeneous soil-filling, creating ideal conditions for sustainable root development and stormwater management, harmoniously integrating with the city’s additional underground utilities.

Every RootBox unit consists of frames, supporting legs, geotextile fabric and connectors, to ensure optimal drainage.
