The Presto Geoweb® system provides a wide variety of　economical, flexible protection treatments for open channels and　hydraulic structures. The system provides stability and protection of　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 topsoil/vegetation by confining them within the cellular structure.
• With concrete infill, produces a flexible slab for a long-lasting armored channel lining at a lower cost than articulating block systems.
• Can be designed for specific site conditions based upon compatibility with local environmental, ecological and aesthetic requirements, maximum anticipated flow conditions, and associated hydraulic stresses.
• Surface roughness and hydraulic efficiency of the lining system can be changed to control flow.

Geoweb® system benefits
Cost-effective structure confines selected infill material to resist anticipated hydraulic flows and associated stresses.

• Supports vegetation in low-to-high intermittent flow channels.
• Allows the use of on-site aggregates in low-to-moderate flow channels, reducing construction costs.
• Provides protection to geomembrane-lined channels and containment systems.
• With concrete infill, provides flexible, inexpensive hard-armored protection against severe high-flow conditions, wave action and associated stresses.

INFILL OPTIONS
A variety of infill materials can be used with the Geoweb® system based upon the requirements of the specific project/problem.

• Topsoil with various selected vegetation.
• Aggregates of varying size and gradation.
• Concrete of various strengths and surface finishes.
• Combinations of the above to meet special conditions.

TYPICAL APPLICATIONS

• swales and drainage ditches
• storm water diversion or containment
• process water channels or containment
• spillways/down chutes/drop structures
• culvert outfalls
• intermittent or continuous/low to high flow channels
