Gabions are delivered to site flat-packed, where upon they are assembled, lifted into position, and filled with a hard durable rock. The main advantages of gabions are their strength and flexibility.
Gabions are wire fabric containers, uniformly partitioned, of variable size, interconnected with other similar containers and filled with stone at the site of use, to form flexible, permeable, monolithic structures such as retaining walls, sea walls, channel linings, revetments and weirs for earth retention.
Gabions form flexible retaining structures that can accommodate
differential settlements. They are also permeable eliminating the main
cause of instability of soil retaining structures. Gabions have also
been shown to provide a good balance between engineering requirements
and environmental considerations for earth retaining walls in rivers,
along roads and railways.
