Urban Forestry

Plant a big idea. Watch it change a city.

DeepRoot Green Infrastructure develops solutions to enhance urban forests and surrounding watersheds in city streets, parking lots, campuses, and other heavily-paved areas. Silva Cell, our flagship product, is an underground framework for containing lightly compacted soil that supports large trees and absorbs runoff from rain, increasing air and water quality, reducing energy loads, mitigating heat island effect and nurturing trees for a long life in their communities. Headquartered in San Francisco with locations in Vancouver, and London, DeepRoot has more than forty years of experience helping trees thrive in cities, nurturing over 500 blocks of urban treescape in the built environment around the world.


Vision and History

DeepRoot was founded in 1976 when an industrial designer tripped on an uprooted sidewalk and ruined a new pair of shoes. This eventually led him to develop the first commercially available tree root barriers. From that simple start, we are now a leading urban landscape products and ecosystem services supplier, focused primarily on integrating trees, soil, and stormwater into the urban environment. Our products include Silva Cell, Root Barrier, Geomembranes (Water Barrier/Bamboo Barrier), and ArborTie staking and guying material. We hold several patents protecting our designs.

Our vision is to create thriving, resilient urban ecosystems comprised of mature, vigorous trees and healthy watersheds. We are committed to enhancing the built environment with innovative and quality products and services that create green infrastructure. We believe this is essential to the creation of healthy and thriving urban spaces.


What is it like to work with DeepRoot? We see our mission as integrating holistic natural elements into the built environment, and our business practices follow the same principle. From initial concept through planning stages, and implementation, DeepRoot supports you every step of the way. We also give back to the design community through research, case studies, and support of industry organizations.
