Gabions were originally developed for the reinforcement of slopes in landscaping, road and hydraulic engineering, but are now also very popular for the design of private and public outdoor facilities.
They consist of stone baskets, usually galvanized and welded steel wire mats, which are stabilized with spacers and filled with suitable material. Pebbles, glass blocks and gravel made of basalt, granite, limestone, dolomite or quartzite are suitable as filling material. The baskets can also be filled with layered branches, tree trunks, glass bottles or clay bricks.
Gabions can be used as a parapet-height enclosure, as a continuously high privacy wall or as stone columns between wooden and metal fences. Depending on the substrate and the size and slenderness of the gabions, a suitable fastening is required.
With small wide walls (h < 1.0m, w > 0.3m) and a stable surface, the stone baskets can usually simply be placed on suitable garden slabs. For slender walls (h >1.0m, w < 0.3m), more elaborate types of fastening are required: For middle walls, metal posts or hardwood posts can be hammered into the ground. The wire baskets are then built around these posts and then filled, so that the posts are no longer visible. In the case of high and slender privacy walls, strip foundations can be useful or necessary, in which support pipes can be installed, which are then integrated into the wire baskets, also invisibly.
There are also gabion fence systems in which profiled sheets serve as posts. By hanging double bar mesh mats in these profiles, a gabion fence is created that can be filled as required.
