Geoweb Erosion Control

Hoofmark (UK) Ltd Geoweb can be used in many slope protection applications meeting a wide range of performance and aesthetic requirements. The three-dimensional system confines the infill material to resist hydraulic flows, inhibit erosion and minimize the downward migration of embankment materials. Single or multi-layered slope protection systems provide solutions for a wide range of structural and run-off problems.

 

A variety of infill materials can be used with the Hoofmark (UK) Ltd Geoweb system. The choice of infill materials is based on the specific project/problem.

Infill materials include:

• Topsoil with various selected vegetation
• Aggregates from sand and gravel to larger rock or stone
• Concrete of various strengths and surface finishes
• Combinations of the above to meet special conditions

 

In slope protection applications, the Hoofmark (UK) Ltd Geoweb system minimizes the downward migration of embankment materials by functioning as small check-dams in the upper soil layer. On vegetated slopes it increases erosion resistance by encapsulating and interlocking with the vegetative root zone. It helps prevent rills and gullies from forming, particularly in areas of concentrated flow over erosive soils.

The Hoofmark (UK) Ltd Geoweb cellular confinement system offers a broad range of surface protection treatments for slopes to 45°. The system is designed for flexibility and can be combined with a variety of simple, yet positive anchoring techniques to allow the application of both vegetated and hard surfacing materials on steeper slopes. The Hoofmark (UK) Ltd Geoweb system also provides a means of fully-vegetating slope surfaces that otherwise could not support plant life.

 

The Geoweb system provides long-term stability and effectiveness of slope cover materials. Some examples of Geoweb system slope surface stabilization include:

• Embankment slopes • Dam faces and spillways
• Containment dikes and levees • Shoreline revetments
• Abutment protection • Cut slopes
• Landfill lining and covers • Detention ponds & lagoons

 

Applications:

The inclusion of internal tendons and ATRA® Clip load transfer pins provides a structural support system that maintains the integrity of the impervious liner or cover.  The system directly protects the geomembrane from accidental puncturing, vandalism and natural degradation, and indirectly prevents soil contamination and erosion.
