Abstract
The present invention discloses cellular confinement systems (CCSs) with improved friction with infill at low normal pressure. The invention especially presents novel flaps-containing CCS that includes inter alia a plurality of elongated strips arranged in a side by side pattern, each of the strip is segmentally bonded to an adjacent strip in spaced-apart bonding areas, said bonding areas alternating between the sides of each of said strips, such that when the system is stretched across its width, the strips curl to form a web of cells confined by cell walls disposed between the bonding areas, wherein at least one of the cell walls comprises at least one flap hinged to the wall and friction between the walls and the infill material increases.
