Abstract
A cellular structure includes a plurality of interconnected cells of fabric material. The cells are at least partially filled with a composite fill material that includes a particulate material and a bonding agent. A cellular unit made up of a plurality of the interconnected cells may have an associated load-bearing frame to enable lifting and/or transportation of the structure. The fill material is preferably resilient.
Claims11
A method, comprising:
- at least partially filling an open cellular unit with a first fill material comprising a composite fill material comprising a mixture of first particulate material and a bonding agent, the open cellular unit comprising a plurality of interconnected cells comprising a fabric material, and the open cellular unit being on or in a frame;
- curing the first fill material to provide a layer of a solid bonded composite fill material;
- depositing a second fill material onto the layer of the solid bonded composite fill material, the second fill material comprising a second particulate material, wherein the second particulate material is the same or different from the first particulate material;
- and
- using the frame to lift and/or transport the filled open cellular unit.
