Gabion retaining walls directly address changes in grade by means of stacking and reinforcing a series of gabion baskets. Maccaferri Strong Face gabions are an excellent solution for use when a gabion wall, or revetment needs a stronger than normal face. The units can be used where there are higher loads within the gabion structure or in situations where a higher abrasion resistance is required on the face of the gabion. This can occur for example in river or lake works where there is the risk of ice movement and increased potential for damage.
Gabion retaining walls consist of permeable facing baskets to prevent pour water pressure from building up behind the wall. In order to obtain higher abrasion resistance and to improve the front face strength, the front or one side of gabions is produced with steel wire mesh of diameter 3.4mm. The other faces of the gabion are produced with mesh of diameter 2.7 mm. In order to reinforce the structure, all mesh panel edges are selvedged with a wire having a greater diameter.
