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).
Claims25
A confinement structure comprising one or more open cells for confinement, in use, of particulate fill materials such as soil, sand or aggregate, each one of the one or more open cells comprising one or more walls, the one or more walls including an external wall and an internal wall, the external wall comprising a composite material having a polymeric grid layer laminated to a fabric layer.

21-31. (canceled)
A method of manufacturing an open cell for a confinement structure for particulate fill materials, the method comprising:
- providing a strip of material comprising a polymeric component;
- applying pressure along one or more lines between side edges of the strip of material to form one or more living hinges in the polymeric component;
- folding the strip at the one or more living hinges to align end edges of the strip;
- and connecting the end edges of the strip to form a cell.
34-35. (canceled)
A confinement structure comprising a plurality of interconnected open cells, each of the plurality of interconnected open cells comprising one or more walls including a composite material having a polymeric grid layer laminated to a fabric layer.
