Reinforced steepened slopes provide a cost-effective means to achieve more efficient grade changes than what is possible with conventional unreinforced slopes.

Geosynthetic reinforced steepened slopes are soil structures constructed with a slope face angle up to as high as 80 degrees from horizontal. Typical unreinforced soil slopes are limited to a slope face angle of approximately 30 degrees, or less, depending on the angle of repose of the slope soil.

Reinforced slopes are constructed by compacting soil in layers with RigidGrid while stepping the face of the slope back at an angle. The slope face is protected from erosion by vegetation or other protective systems ranging from concrete slabs to GeoCell walls.

Additional geosynthetic elements are incorporated into reinforced steepened slopes to facilitate drainage, minimize ground water seepage and to assure stability of the steepened slope and erosion resistance of the face.
