- System Summary
- The Eco-Grass system is a pre-grown, instant green looses-laid system with a low maintenance grass blanket consisting of fine fescues. It is harvested like sod and rolls on top of semi-intensive engineered growing medium. Eco-Grass helps reduce water evaporation, soil erosion and weed growth. Components are easy to transport and install (adapted from the manufacturer's literature).
