Shore up steep embankments and prevent severe erosion on slopes and channels with the GEOWEB® System. The 3D cellular network prevents sheet flow from causing scour and erosion on slope surfaces. Confinement of infill allows smaller rock or vegetation in place of larger, costly rip rap. With concrete infill, the system is a flexible, hard-armor solution — more economical than reinforced concrete or articulated concrete blocks (ACBs). For grassed areas prone to concentrated erosion, GEORUNNER® Mats offer protection from scour.
