Sack Gabion

Sack gabions are cylindrical 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 gabions 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.
Our new PA6 polymer coating has been added to our range of protective coatings to offer a solution to those projects that require improved environmental and technical performance to the existing PVC and HDPE coated mesh products on the market.
The mesh used to make sack gabions 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).

Please contact your local Maccaferri subsidiary for details on the compliance and certification in your area.

Cylindrical Gabion

The cylindrical gabions are cylindrical structures made from double twist 8×10 cm hexagonal wire mesh with mechanical properties greater than those specified in UNI-EN 10223-3, certified in accordance with the “Guidelines to draw up specifications for the use of double twist wire netting” issued by the National Public Works Council – Central Technical Service (Certified Product No. 226/001).
These elements are adopted for the protection of banks and embankments, for the construction of gravity support works, for retaining unstable slopes which have a “substantial structural importance” and, as such, must have the requirements specified in the Technical Standards for the Works under Ministerial Decree 14 September 2005 and subsequent amendments.
The cylindrical gabions are filled with stones on site to create a flexible and permeable structure to be used for river bank protection works and emergency works. The cylindrical gabions are fitted with reinforcement bars inserted in the mesh during manufacture to facilitate the closing during installation.
