Gabions
Wave Height Range: Above five feet.
Gabions are rectangular baskets or mattresses made of galvanized, and sometimes PVC-coated,
steel wire, in a hexagonal mesh (Figure 57). , Subdivided into approximately equal sized cells, standard
gabion baskets are 3 feet wide, and available in lengths of 6, 9 and 12 feet and heights of 1, 1. 5 and 3
feet. Mattresses are either 9 or 12 inches thick. At the job site, the baskets are unfolded and assembled
by lacing the edges together with steel wire. The individual baskets are then wired together and filled
with 4- to 8-inch diameter stone. The lids are finally closed and laced to the baskets, forming a large,
heavy mass (Figure 58).
