Confinement structures
First Claim
1. A confinement structure comprising a plurality of interconnected open cells for confinement, in use, of particulate fill materials, each one of the plurality of interconnected open cells comprising one or more walls, the one or more walls including an external wall having a single integral material and an internal wall, the single integral material comprising a composite material having a polymeric grid layer laminated to a fabric layer;
- and wherein the single integral material includes at least one living hinge formed in the single integral material;
wherein the one or more walls are pivotally connected using a mechanical hinge comprising a hinged piece of flexible fabric material.

Abstract
A confinement structure comprises one or more open cells (70) for confinement, in use, of particulate fill materials such as soil, sand or aggregate. The cells (70) comprise walls (72) formed of a composite material comprising a polymeric grid layer laminated to a fabric layer. The walls (72) may be formed from a strip of the composite material comprising one or more living hinges. The cells (70) may be provided with skirt portions (74) that extend from at least some of the walls (72).
