Modular drainage grating for green areas
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. 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.
