Sack gabions are cylindrical gabion baskets engineered from double twisted hexagonal woven steel wire mesh
The tubular units are filled with gabion stone at the project site and laced tightly shut. This modular unit is then used to provide erosion protection for river banks, scour protection of bridge piers, or any situation that requires immediate defence from the erosion effects of water. The sack gabions are lifted into position using suitable equipment and simply stacked upon one another to form a mass of contained rocks.
The mesh is made from high quality steel wire, which is heavily galvanised to provide long term corrosion protection. An additional protective polymeric coating is also applied in more aggressive environments, or where a longer design life is required.
Sack gabion baskets are supplied with steel reinforcing wires inserted during the manufacturing process to facilitate closing during installation. In order to reinforce the structure, all mesh panel edges are selvedged with a wire having a greater diameter.
The mesh used to make sack gabion baskets are manufactured in our factories around the world. The management and production system in many of our factories is certified in compliance with ISO 9001.
In selected factories, the mesh is produced in compliance with CPR – Construction Product Regulation 305/2011, having EC marking in compliance with ETA-09/0414. The management and production system is certified in compliance with ISO 9001 and ISO 14001 (related to the environmental management system).
