SOLUTIONS FOR CONTROLLING EROSION AND SCOUR ON EMBANKMENTS

Stabilize soils on steep embankments and prevent severe erosion problems. Prevent the formation of rills and gullies and scour caused by stormwater runoff and concentrated flows. Protect geomembranes and minimize sliding of cover materials on landfills and containment basins.

PROTECTION FROM EROSION

The Presto GEOWEB® system is a proven solution to challenging erosion problems. The system provides a structurally-stable environment for infill and effective, long-term solution for controlling erosion on embankments.

PROTECTION OF SLOPES and SHORELINES:

• Delivers stability and long-term sustainability of embankment materials.
• The 3D system confines and reinforces the upper soil layer to resist erosive conditions and sliding forces.
• Confined infill allows slopes to be designed and constructed steeper than when unconfined, saving land costs.
• Ideal for vegetation, permeable aggregate or hard-armored concrete.

PROTECTION OF CHANNELS:

• Stabilizes and protects channels exposed to erosive conditions of all types.
• From low to high flows, intermittent or continuous, the system can be designed to withstand the highest velocities.
• Combined with a TRM, the vegetated Geoweb system can withstand velocities as high as 30 ft/sec (9m/sec).* Replace costly and high-maintenance rip rap with more attractive stabilized vegetation in drainage ditches, swales and stormwater channels. *Geoweb/TRM Research Colorado State University
• Confinement also reduces aggregate requirements**, allowing smaller, less-expensive aggregate. For higher volocities, concrete infill provides hard, durable protection. **Geoweb/Aggregate Research Colorado State University

PROTECTION OF GEOMEMBRANES:

• A proven solution for stabilizing and minimizing the sliding potential of infill materials over impervious liners.
• High-strength tendons are integral when anchors cannot be used. Tendon details are part of the complimentary design evaluation Presto offers.

PROTECT FROM SURFACE SCOUR

Protect against erosion caused by concentrated surface flow with the Presto GeoRunner Flow Protection mats.

• Mats can be easily placed and anchored to minimize scour from concentrated flows in spillways and culvert outfalls, or from fluctuating water levels on shorelines or channel embankments.
• Because they are light-weight and less-costly, contractors prefer them over concrete mat systems.
