The Silva Cell is modular suspended pavement system for containing lightly compacted soil underneath paved surfaces for large tree growth and on-site stormwater management. This specialized tool enables you to make your site more ecologically and economically sustainable through the use of green infrastructure.
Each Silva Cell is composed of a frame and a deck. The Silva Cell frame is 48'' (1200 mm) long x 24'' (600 mm) wide x 16'' (400 mm) high. 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. Silva Cells can be spread laterally as wide as necessary. Each unit is approximately 92% void space, making it easy to accommodate 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. This means that hardscapes supported by the Silva Cell are in no danger of sinking due to compressive forces.
The Silva Cell frame is 48'' (1200 mm) long x 24'' (600 mm) wide x 16'' (400 mm) high. The deck is a rigid platform with six recesses that snap securely on the six posts of the frame. Openings on the deck allow ample room for air and water to penetrate and nourish the enclosed soil. Diagonal channels on the upper portion of the deck house two galvanized steel tubes that prevent deformation of the posts and help eliminate plastic creep.
