GEOWEB 3D Channels offer stability and protection of channels exposed to all ranges of hydraulic and erosive conditions. Build green vegetated channels for intermittent flows.  With an overlying TRM, GEOWEB vegetated channels can withstand flows up to 30 ft/sec (9m/sec)! Design concrete filled GEOWEB channels to resist continuous, high flows.  Eliminate the need for costly rip-rap, gabions and articulated concrete blocks (ACBs). Free Project Evaluation service.
