Wire mesh for making of gabion sacks is hexagonal opening with the aperture of 80x100mm, the wire diameter of 2.7mm and selvedge wire of 3.4mm diameter.

Sack gabions are cylindrical baskets made of 8x10 double twisted steel woven wire mesh.

How to use: Sack gabions filled with stones are used in river control and various emergency works. Sack gabions are supplied with steel reinforcing wires inserted during the manufacturing process to facilitate closing during installation.

Treatment: Wire for making of sack gabion is electro galvanized.

Dimensions and sizes of galvanized sack gabions can be customized.

Assembly
The folded Sack Gabion units shall be taken out from the bundle and placed on a hard flat surface. They shall be opened, unfolded and pressed out to their original shape ready for assembly.

Foundation preparation
The foundation on which the Sack Gabions are to be placed need not be levelled and graded as Sack Gabions are used for the purposes of providing a firm platform in areas where poor founding conditions exist or in areas where founding occurs in the wet.
Appropriate measures shall be taken for separation of the foundation layer from the rock filled Sack Gabion in accordance with the project specifications (geotextile, drain works, etc.). Geotextiles required to be installed behind or underneath the Sack
Gabion structures shall comply with the requirements of the project specification.

Lacing
Sack Gabions are assembled by rolling the mesh panel into a cylindrical shape and overlapping the selvedged edges. By pulling and tightening the lateral spiral wire, the edges are secured. Excess spiral wire shall be secured around the selvedge wire by looping and twisting the wire around itself. Once the longitudinal overlap is secured, the one end of the cylinder can be laced closed. This is accomplished by pulling the two ends of the bottom spiral tightly together and securing by again looping and twisting the wire around itself (Figure 1)Care shall be taken to avoid damaging the wire coating. The remaining end of the cylinder is left open to allow the Sack Gabion to be filled with suitable stone.

Placement
To facilitate placement, Sack Gabions can be placed individually or in pairs, provided they are laced together. When lifting Sack Gabions, care should be taken to lift the Sack Gabion by the
thicker overlapped selvedge wires (Figure 3).
