Use the Silva Cell to meet your project's sustainability goals and improve the ecological function of your site. The Silva Cell makes it easy to use trees and stormwater to enhance your designs through the integration of these ”green” utilities.
Each Silva Cell is composed of a frame(s) and a deck. Frames can be stacked one, two, or three units high before they are topped with a deck to create a maximum amount of soil volume for tree root growth and stormwater treatment. The Cells can be spread laterally as wide as necessary – the Silva Cell is approximately 92% void space, enabling it to easily accommodate most surrounding utilities.

Six rigid vertical posts protrude from the bottom of the frame to support hardscapes along with the weight of any load they carry. The posts have a cross-sectional shape that maximizes axial rigidity while also preventing the posts from telescoping together when the Cells are stacked upon each other. Their rounded edges prevent significant stress concentrations. This means that hardscapes supported by the Silva Cell are in no danger of sinking due to compressive forces.
The deck is a rigid platform with six recesses that are positioned to rest securely on the six posts of the frame. There is also a snapping mechanism on the deck to fasten it to the frame. Openings on the deck allow ample room for air and water to penetrate and nourish the enclosed soil. There are two diagonal channels on the upper portion of the deck that house two galvanized steel tubes. These tubes prevent deformation of the posts and help eliminate plastic creep.
