The Silva Cell is a modular subsurface integrated tree and stormwater system that holds unlimited amounts of soil while supporting traffic loads beneath paving and hardscapes.

The Silva Cell meets H-20 loading standards and can be used in a wide variety of tree and stormwater management applications of any size. They make it possible for streetscapes, plazas and parking areas to support healthy, thriving trees without compromising above ground surface areas. They can act as a bridge, linking street tree roots up with nearby soil volumes like parks and lawns in break-out zone applications, and they can support green walls and green roofs to help transform under-utilized spaces into living resources. Because of its modular design it can easily accommodate surrounding utilities and varying depths on any site.

The healthy soil housed within the Silva Cell serves two important functions: growing large trees and treating stormwater onsite. The integration of green utilities like soil, trees and water into our urban areas substantially improves their design sustainability and helps alleviate some of our most pressing ecological challenges – including air and water quality, rising temperatures, flooding and erosion from daily rainfall events.

The Silva Cell can be applied to different green building certification programs, including LEED and BREEAM. Please contact us at This e-mail address is being protected from spambots. You need JavaScript enabled to view it to learn more.
