Introduction Municipal street reconstruction is often triggered by aging underground infrastructure: water mains, sewer lines, utilities, sidewalks, curbs, or drainage systems that have reached the end of their service life. But once a street is opened up, the project becomes more than a repair. It becomes a planning opportunity. Instead of simply replacing old infrastructure… More
Introduction Helping cities grow trees is what we do at DeepRoot — but it’s important not to think about tree count as the sole metric in achieving urban canopy goals. Thriving tree canopies are built one tree at a time, one project at a time, through individual decisions that determine whether a tree merely gets… More
Introduction: Supporting Tree Success with the Strongback With Silva Cells, the strongback — our temporary installation lid used during soil placement — is not an afterthought or a mere convenience: It’s an intentional design element that plays a critical role in how soil enters the system, gets compacted, and ultimately performs for trees. This Silva… More
Download our research overview document here. Today, the idea that urban trees need real soil volume to reach maturity is no longer controversial — it’s widely accepted among urban foresters and landscape architects. We also recognize that providing that soil volume, especially with systems like Silva Cells, represents a meaningful upfront investment. But decades of… More
Introduction People often ask us how Silva Cell grows large trees and treats stormwater. The truth is: it doesn’t. At least not by itself. Silva Cell isn’t some magical, mechanical device that generates roots or filters water on its own. Instead, it’s a simple yet powerful framework that lets nature perform at its best, even… More
Introduction For nearly two decades, contractors have been installing Silva Cells in urban forestry and stormwater projects around the globe. From city streetscapes to major civic redevelopments, crews on the ground have consistently shared feedback on what matters most: efficient installation, reliable support, and lasting results for trees and soil. Their voices highlight not just… More
Introduction Why are streetlights and sidewalks considered municipal assets — but not trees? Most cities manage detailed inventories of their physical infrastructure: light poles, sewer lines, benches, trash bins, snowplows. These things are logged, valued, maintained — and budgeted for. They’re viewed not just as integral components of the public realm, but as long-term investments… More
DOWNLOAD A 1-PAGE PDF VERSION OF THIS CONTENT HERE Future-Proofing Your Stormwater Projects The UK’s updated SuDS standards, released in June 2025, outline clear priorities for managing stormwater in new developments — these principles include managing runoff at the source, mimicking natural drainage, reducing flood risk, improving water quality, and supporting long-term biodiversity and amenity….

Introduction Silva Cells grow healthy trees and manage stormwater in built environments all over the world — but there’s something especially meaningful about Silva Cell projects on school and university campuses. These spaces are more than just places to pass through — they often feel like a second home for students, faculty, and staff, who… More
Introduction Silva Cells were the first commercial soil cell product on the market, but did you know the idea of suspended pavement systems date back many years to urban European streetscapes? From Paris and London to Boston and Redwood City, let’s take a brief tour through the use and evolution of suspended pavement systems throughout… More
The pre-installation meeting is one of the most important — and free! — services offered by DeepRoot. They provide an opportunity for a DeepRoot representative to meet with installing contractors prior to the start of their Silva Cell installations to help ensure that they’re comfortable with the installation process. What are the details of these… More
Do you need to have prior Silva Cell experience to install the system? No! Our Standard Specifications call for Silva Cells to be installed by a “qualified installer whose work has resulted in successful installation of planting soils and planter drainage systems, underground piping, chambers, and vault structures.” In other words, contractors can meet these… More
