Last month’s webinar by our Technical Director, Pat Greeley, on the topic of integrating Silva Cells and utilities was our best attended, ever, by far (far). We know how important this topic is, and the seminar was a great opportunity to share everything we’ve learned from the nearly 400 installations we’ve completed.
Today I’m very excited to introduce a new feature on the blog called Ask Jim Urban. Jim Urban, FASLA is an expert on urban trees and soils and his recent book, Up By Roots, is the industry bible on these topics. Jim was also involved in the development and design of the Silva Cell system…. More
For the last two weeks of December I’ll be reprinting some of our favorite blog posts instead of putting up new ones.

Today’s post from monthly guest author Ellyn Shea is about a truly important, but often overlooked, issue: protecting existing trees during construction. I’m a sucker for success stories, and this is a great one. -LM Every time we lose a mature tree, we lose those benefits. A young replacement tree takes up to 30 years… More

Broadway Avenue, in Winnipeg, which went in the ground in July 2007, was one of our first Silva Cell installations. Several years later, they had a planned… More
Today we’ll look at how to do an emergency repair of a Silva Cell system. This simulated repair was done at a demonstration site in Toronto and was a joint test site between Toronto Water and the City. First, a water pipe was installed. A hole was cut in to the pipe. Once the water was… More
The Silva Cell works with all types of paving. During a recent webinar, one participant asked if settlement is a concern in areas where unit pavers have been installed continuously over both Silva Cells and the adjacent soil subgrade. Good question.
Man. The day is finally here. The Silva Cell installation guidelines are now available on our YouTube channel.
As an urban trees and soils consultant, I am always looking for studies that examine how trees survive and adapt to the built environment. One of the biggest questions and confusions I encounter is the issue of whether organic matter (something that I discussed in a previous post) needs to be added to urban… More
