EnviroGrid cellular confinement system (CCS) is ultrasonically welded high density polyethylene (HDPE) strips that form a lightweight, expandable honeycomb structure. EnviroGrid is designed for use in soil stabilization, erosion protection, retaining walls and channel protection. Soil Stabilization: Use over weak soils and fill with soil and vegetate, or fill with sand or angular rock. Erosion Protection: Place on slopes as steep as 1:1 and vegetate. Retaining Walls: Stack layers to desired height, fill each layer with available on site materials. Channel Protection: Depending on flow velocities, fill with top soil and vegetate, or with angular rock or concrete. It can also be used for low water crossings.
