KELLOGG MIDDLE SCHOOL

Kellogg Middle School in Shoreline, Washington, used their 2017 renovation to mimic the headwaters they were built upon in the 1950s, cleaning and slowing stormwater before it enters Thornton Creek

Sized to Fit Your Needs

Using Silva Cells to grow large, healthy trees? The first step is setting your soil volume goals.

Soil Volume Target

Soil Volume Equals Tree Health

One of the primary obstacles facing urban trees is soil compaction, which is inhospitable for root growth. Silva Cells eliminate this challenge by providing support to the hardscapes above and allowing its void space to be filled with nutrient-rich, uncompacted soil — and the more the better. Research proves that nurturing trees to maturity is best achieved with a robust bank of soil.
