SILVA CELL OVERVIEW
Grow large, healthy, long-living trees
Manage stormwater on-site
Create a high-performance landscape in the urban environment

The Silva Cell is a modular suspended pavement system that uses soil volumes to support large tree growth and provide powerful on-site stormwater management through absorption, evapotranspiration, and interception.

Each Silva Cell is composed of a frame and a deck. Frames are 48'' (1200 mm) long x 24'' (600 mm) wide x 16'' (400 mm) high, and each one holds 10 cubic feet (.28 cubic meters) of soil. They can be stacked one, two, or three high before they are topped with a deck to create a maximum containment area for lightly compacted loam soil. Silva Cells can be spread laterally as wide as necessary. Each unit is about 92% void space, making it easy to accommodate utilities.

FRAME
Six rigid vertical posts protrude from the bottom of the frame to support hardscapes along with the weight of any load they carry. Their rounded edges prevent significant stress concentrations, meaning that the supported hardscapes are in no danger of sinking due to compressive forces.
DECK
The deck is a rigid platform with six recesses positioned to snap securely on the six posts of the frame. Openings on the deck allow ample room for air and water to penetrate to the enclosed soil.
