Introduction As the sun blazes on another hot summer day, the thermometer on the east side of town is likely to display the same number as its counterpart three miles west — but this doesn’t tell the whole story. The way we experience heat, particularly in developed urban areas, is influenced by a number of… More
Introduction The space constraints of dense city environments present a challenge for project planners implementing an urban forestry element. There are, however, a number of solutions to help improve conditions for healthy tree growth. The Silva Cells are one such choice, a suspended-pavement system allowing for maximum soil volume. Another option is structural soil —… 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
We get asked to compare Silva Cells to CU Soil with some frequency. It’s a comparison that we always hesitate to make, because to us it’s really a case of apples and oranges. While they may seem to be solutions to the same challenges, there are some very significant differences that affect their value and performance for tree growth… More
Introduction “The fighters are our salvation but the bombers alone provide the means of victory.” Winston Churchill’s words from September 1940 were prophetic, an early forecast of the indispensable role these aircraft would play in the triumph over Nazism in World War II. Dedicated to the courageous veterans of the Bomber Command, a bronze memorial… More
Introduction It’s August 12, 1884, and geologist Joseph Tyrrell — on the hunt for coal seams in Alberta’s Red Deer Valley — discovers something far different: the first dinosaur fossil ever found in the region, later named the Albertosaurus for its geographical lineage. A hundred years later, the Tyrrell Museum in Drumheller, an homage to… More
Introduction One can’t help but feel a sense of patriotic reverence, climbing the 136 steps to the monument’s main west entrance and looking out over the U.S. Capitol across First Street — a sensation no doubt intended by Cass Gilbert and William Taft, the building’s architect and chief lobbying advocate, respectively. This is the U.S…. More
Introduction The first licensed airfield in Canada, City Centre Airport opened in 1927 on 144 acres of land just north of Downtown Edmonton. Serving as a military airbase during the Second World War, it became a stop on international passenger flights between North America and Asia in the 1950s. As jet technology progressed during the… More
Introduction From New York City’s Metropolitan Museum of Art to Wembley Stadium in London, DeepRoot has helped ensure the success of green infrastructure projects in big cities across the globe. But these high-profile initiatives are only part of our story — Silva Cells grow large trees in towns big and small, partnering with designers, engineers,… More
A recent research study conducted by Bartlett Tree Research Laboratories tackled the question of the best methodology to grow trees in cities, with the ultimate goal of reaping benefits that mitigate the impact of climate change. The study (Comparison of Tree Responses to Different Soil Treatments Under Concrete Pavement) was produced by Dr. E Thomas… More
