Geoweb Slope Protection
Geoweb® structurally holds infill materials from sliding or creeping down steep slopes. With infills as diverse as topsoil, gravel and concrete, project owners and designers have flexibility in their approach to performance, aesthetics and economics. The mechanical functions of Geoweb augment the erosion control performance of infill materials, enabling them to resist significantly greater stresses than would otherwise be possible. And in the case of sheet or shallow concentrated flows over gravel and topsoil, the cell walls act as a series of check dams, forcing the water to ride above the surface, effectively controlling rill and gully formation.
Geoweb sections are flexible, allowing contractors to secure Geoweb to any reasonable subgrade contour. The cell depth range from 3" to 8", combined with a high cell wall stiffness, makes infill depth determinations simple and easy to construct - no costly form work and no site ‘guesswork’ required to obtain the desired infill thickness.
Geoweb’s unique wall perforation pattern ensures safe down-slope transport of infiltrated stormwater or collected subsoil seepage. Further, the perforations enable strong root system development among cells and cell wall to infill bonding when concrete is used as the infill. Geoweb slope protection systems remain flexible, negating the effects of minor to moderate subgrade movements caused by frost, swell or subgrade settlement.
Due to the product's flexibility and reliable weld strength, coupled with a wide selection of infill materials and securing techniques, Geoweb slope fascias are effective and economical for a diverse range of applications, including:
Oversteepened vegetated slopes
Wastewater and water lagoon slopes subjected to wave/ice impact
Overpass abutment slopes
Animal waste lagoon slopes
Landfill cell [liner] slopes subjected to impact, UV and heat stresses
