    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.Geocell are typically loaded by the live loads on the surface and the overall structure is tensioned while the underlying foundation soil settles. Geocells are regularly used for soil confinement on steep slopes to prevent severe erosion. The geocells are sometimes installed even over slippery geomembranes to contain and reinforce the cover soil.The geocells in these applications should withstand high tensile stresses both in the strands and the junctions without breaking and sliding down the slope. A need for more accurate and specific geocells testing is needed by the design engineers when designing such a critical applications. The testing procedures appropriate for geocells will be investigated, performed and analyzed in this paper. The description of the above tests and some preliminary results are presented and discussed. A final proposal for test standards concerning geocells will be presented for consideration by the existing geosynthetics testing committees.
