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.

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
