Our mission is to create a more livable built environment, providing a high level of ecosystem services, by using green infrastructure like trees, soil, and Sustainable Urban Drainage Systems (SUDS).

Working with DeepRoot Silva Cells


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. The DeepRoot 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.


Our Values

“Liverpool City Centre is changing for the better. The improvements to The Strand, reducing traffic, more space for pedestrians, and especially the new top-quality cycle lanes, are immense. It will do so much to reconnect our world-famous Waterfront with the rest of town.”
– Liverpool Cycling Commissioner, Simon O’Brien
