Geoweb Cellular Confinement System Channel Protection

The Geoweb® channel protection system provides a wide variety of flexible protection treatments for open channels and hydraulic structures.

The system provides stability and protection for channels exposed to erosive conditions ranging from low-to-high flows either intermittent or continuous.

• Greatly improves the hydraulic performance of conventional protection materials such as aggregate, rip-rap and vegetation by confining them within a cellular structure.
• Can produce a flexible concrete slab for a low-friction armoured channel lining.
• Can be designed for specific site conditions based upon compatibility with local environmental, ecological and aesthetic requirements, maximum anticipated flow and associated hydraulic stresses.
• Surface roughness and hydraulic efficiency of the lining system can be changed to control flow.
• Subgrade drainage requirements and deformation potential within the structure can be addressed.

Typical Applications

• Swales and drainage ditches
• Storm water diversion or containment
• Process water channels
• Spillways, down chutes, drop structures
• Culvert outfalls
• Intermittent or continuous/low to high flow channels

Perforations facilitate parallel slope drainage of the infilled cell. In saturated conditions, the removal of excess water increases infill friction, reducing down-slope sliding forces, resulting in a more stable system.

In vegetated systems, perforations allow roots to grow from cell to cell, creating greater vegetative stability against short-term hydraulic events.
