The use of geocells in base reinforcement of structural fill allows confinement of the soil from lateral spreading, therefore preventing shear failure, and increasing the soil bearing capacity. Geocells are typically loaded by the live loads on the surface and the overall structure is tensioned while the underlying foundation soil settles. These are regularly used for soil confinement on steep slopes to prevent severe erosion. These are sometimes installed even over slippery geomembrances to contain and reinforce the cover soil.
