GreenGrid^® systems provide many features that no other green roof system offers:

Modules – Patented GreenGrid^® modules are composed of 60% post-industrial, recycled, high molecular weight polyethylene. The modules come in a variety of sizes and are available in three depths. The Ultra Extensive (2.5-inch depth) modules – supporting only sedum species – weigh only 11-13 pounds per square foot (wet). The Extensive (4-inch depth) modules – supporting shallow rooting grass, sedum, and wildflower species – weigh approximately 18-22 pounds per square foot (wet). The Intensive (8-inch depth) modules – supporting a large variety of ornamental perennials and shrubs – weigh approximately 35+ pounds per square foot (wet).

Growing Media – GreenGrid^® is a proprietary mixture of organic and inorganic material, formulated on the basis of years of research and field testing by soil scientists and horticulture experts.

Preplanted Vegetation – GreenGrid^® modules arrive at the jobsite preplanted and ready for installation on the roof. Plants can be selected by GreenGrid^® or specified by others.

Drip Irrigation Systems – The optional drip irrigation system (typically selected for Intensive systems) is designed for even watering of the plants. For many geographic areas/climates plants can be selected to withstand drought conditions.

Ecoballast^® – Filled with aggregate, Ecoballast^® provides a modular roof ballast with pre-determined water retention capability.

Edge Treatments – Wood, recycled composite wood, metal, or other specialty materials (in various colors and designs) can be included as part of the GreenGrid^® system design.

Optional Features – Pavers made from 100% post-industrial recycled rubber, walkways, water ponds, outdoor furniture, and planter boxes can be incorporated into the GreenGrid^® system.
