StormTank® - Urban Root System
The StormTank Urban Root System ensures the long-term health of your urban canopy trees while protecting sidewalks, curbs, and pavement from root damage. The StormTank Urban Root System is a robust, soil-supporting containment structure utilizing StormTank 25 Series Modules. This system supports AASHTO HS-25/HS-20 heavy vehicle loads while creating a void space for uncompacted soil – allowing for unobstructed root development and improved tree health.Most popular related searches

Urban tree planting faces long-term risks due to the competing demands of typical streetscape features – such as sidewalks, pavement, curbs, and utilities – and the need for healthy canopy tree development. Pavement subgrade is often compacted to 95% Standard Proctor density, while most canopy trees require a lightly compacted soil density, typically below 80%. Compacted soil restricts root space, which can lead to tree failure as they mature. Constrained roots can also damage pavement and sidewalks as they grow. This ultimately creates dead space in the streetscape design and hazardous conditions for pedestrians.
