Sack Gabions
Sack gabions consist of a single mesh panel made of hexagonal woven wire Mesh Type 80, commonly referred to as double twist wire mesh as per SANS 1580:2005 Sack gabions are filled with rock at the project site to form flexible, permeable, monolithic structures used for emergency and river training works where local conditions require fast installation or where the water does not allow for easy access to the site and where underwater installation is necessary.
The steel wire used in the manufacture of the sack gabion is
heavily Galfan coated Class A as per EN 10244-2 . If
required, a PVC coating is extruded over the Galfan wire to
provide added protection for use in aggressive environments such
as acidic soils and water, in salt water, in water carrying a high
abrasive sediment load or wherever the risk of corrosion is
present. The PVC coating has a nominal thickness of 0,5 mm.

In order to reinforce the structure, all mesh panel edges are
selvedged with a wire having a greater diameter than the mesh
wire. Dimensions and sizes of Galfan and PVC coated sack
