Geocells along with anchoring techniques ensure the long-term stability of slopes using vegetated topsoil, aggregate, or concrete surfacing. The enhanced drainage, frictional forces, and cell-soil-plant interaction prevents downslope movement and limit the impact of raindrops, channeling, and hydraulic shear stresses.

Geocell effectively controls erosion as the cells prevent movement of the infill. The confined infill therefore acts as a counterweight on sloped areas and improves stability. Perforations in the 3D cellular confinement system allow the passage of water, nutrients, and soil organisms. This encourages plant growth and root interlock, which further stabilizes the slope and soil mass, and facilitates landscape rehabilitation.
