GEOWEB® – 3D Geocell Permeable Channels

Replaces costly, higher-maintenance rip rap with lower maintenance, less expensive stabilized vegetation.
Effective in low flow channels with low-to-high intermittent flows. With an overlying TRM, can withstand velocities as high as 30 ft/sec (9m/sec). See GEOWEB with TRM Vegetated Research.
GEOWEB tiered channels built as gravity or reinforced retaining walls have an open fascia that allows vegetation, and stormwater infiltration.
Coir fabric wrapped lifts included in the wall design protect against infill loss in conditions with higher anticipated flow velocities.
Engineered fill (comprised of 2/3 open-graded base course and 1/3 topsoil) is a structural fill option allowing roots and water to move freely through the aggregate voids—allows occasional access by maintenance vehicles.

GEOWEB confined aggregate is more stable than when unconfined, allowing smaller, less expensive aggregate in low-to-moderate flow conditions.
Locally available materials can be used as infill, reducing material purchase and transportation costs.
Performance Results: GEOWEB-confined aggregate is more stable than unconfined rip-rap with research showing a 10X reduction in rock size. This reduction offers significant savings in rock, installation and transportation costs. See GEOWEB Aggregate-Infill CSU Research Summary.
