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 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 Soil is the foundation for healthy urban trees. It provides essential space for roots to expand, creating conditions for a mature, wide-canopy tree — but only if it’s actually there in the quantity and quality the tree needs. That’s why soil volume is one of the most important metrics for determining a city tree’s… 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
Silva Cells and On-Structure Installations The DeepRoot Silva Cell system has been installed in dozens of rooftop and on-structure projects around the world. Whether on top of existing structures — such as parking garages — or a garden terrace atop a new construction project, Silva Cells can help create structure as well as bioretention for… More
Introduction When we talk about low-impact development and design today, the term “suspended pavement” is frequently used — but rarely defined. It’s important to understand this practice within the field of green infrastructure, so let’s examine what suspended pavement is as well as its history, uses, composition, and case studies. What is Suspended Pavement? Suspended… More
DeepRoot’s Silva Cell has been installed in dozens of rooftop projects around the world. Whether it is on top of existing structures such as parking garages, or a garden terrace atop a new construction project, Silva Cells can help create structure, bio-retention for tree roots wherever installed. There are two types of green roof installations,… More

I often get asked, “Do you have any Silva Cell installations in New York City?” After more than a decade of Silva Cell presence in the Greater NYC area, I am a bit incredulous that it is not more well-known in the industry. The answer is a definitive “yes!” A review of our projects in… More
This blog is the first in a series of three that focuses on maintenance for Green Infrastructure (GI) systems and includes design considerations for selecting and designing GI systems, developing O&M manuals, and training maintenance staff to maintain the installed GI facilities. Conventional or grey stormwater infrastructure systems require maintenance in order to provide the… More
