What Contractors Are Saying
“Modular nature of DeepRoot's Silva Cells allowed for easy installation and integration with adjacent underground utilities. Direct soil filling into the cells followed by light touch walk-through compaction enabled our team to move fast with cost and performance benefits.”
– Gus Assi, Lead Contractor with Tri Group Construction and Development
“With the open structure of the DeepRoot Silva Cell, compacting the planting soil or fill to the required tolerances is easy. This is true regardless of the configuration. We installed cells, along streets, in rain gardens, in plazas and on structure. No matter where it’s done, it’s the same quick method.”
– Joe Umana, Site Superintendent
“Installing DeepRoot's Silva Cell is very simple and straightforward, there really is nothing to it. The supply and on-site installation support we were given was invaluable, we would happily install the Silva Cells in future projects.”
– Chris Wright, GPL

How It Works

Meet regional stormwater requirements using underground bioretention designed for tight urban spaces. The Silva Cell is a stormwater BMP that leverages soil and trees to provide water quality control, peak overflow reduction and flow control to grow big trees in hardscape environments.

Interception and Evapotranspiration

Large trees intercept and evapotranspire significantly more rain than small trees. For example, a healthy 40 year old Hackberry tree is estimated to provide 14 times as much interception as a 10 year old Hackberry (McPherson et al 2006).

Long-Term Infiltration

As roots grow and then decay, they leave open channels in the soil that restore and/or enhance porosity and infiltration rates. Several studies have found a significant increase in saturated hydraulic conductivity in bioretention with plants as compared to those without (e.g. Lucas and Greenway 2011).

Water Quality Benefits

Vegetation is crucial to many water quality benefits, including removal or sequestration of dissolved nutrients, hydrocarbons, and Total Suspended Solids (TSS). Plants also slow water flow, allowing more time for sedimentation to occur (Hunt et al 2012).

Silva Cells Work With Existing Trees

Silva Cells can be used on sites where existing trees need additional soil volume. The Silva Cells can be installed as close to the tree as the root pruning will allow.
