Designing Marino Cell

Built on Proven Expertise

DeepRoot pioneered the soil cell market nearly two decades ago with the Silva Cell, creating a foundation for healthier cities by merging tree growth and stormwater management in a single system. That experience wasn’t just valuable — it was indispensable in shaping the Marino Cell. With Silva Cell, we learned how to balance surface loads above with open void space below. Now, we’ve pivoted that knowledge into a stormwater-first solution designed for today’s urban challenges.

At the heart of this innovation is Graham Ray, DeepRoot’s CEO, who continues the legacy of a family-run company built on urban sustainability. DeepRoot doesn’t outsource its thinking — we design in-house, drawing on decades of engineering and field experience. That commitment to internal innovation is what has enabled us to reimagine the future of stormwater management with the Marino Cell.

“The learning we took from the Silva Cell was critical to our ability to make the Marino Cell the best possible product.” – Graham Ray

Innovation from the Ground Up

Unlike resellers or distributors, DeepRoot doesn’t market someone else’s invention — we design solutions ourselves. The Marino Cell reflects years of engineering research, consultant collaboration, and field experience. Every detail, from independent modularity to utility-line access on multiple levels, was intentionally developed by our in-house team. These innovations aren’t copy-and-paste features; they’re industry firsts, designed to give designers and cities tools no one else can provide.
