standard construction materials and erosion-control treatments. Geocell products are three-dimensional, expandable panels made
from high-density polyethylene (HDPE), polyester or another polymer material. When expanded during installation, the
interconnected strips form the walls of a flexible, three-dimensional cellular structure into which specified infill materials are
placed and compacted. This creates a free-draining system that holds infill materials in place and prevents mass movements by
providing confinement through tensile reinforcement. Cellular confinement systems improve the structural and functional behavior
of soils and aggregate infill materials.
