Gabions are used as effective solutions to prevent erosion and to stabilize and strengthen embankments. Gabions are described as wickerwork baskets filled with stones or earth, used as reinforcements. .
According to Betafence Gabions Solutions, "Gabions are wire mesh baskets formed by connecting individual panels of mesh with helical spirals on the vertical edge wires creating an open series of box compartments that fold in a concertina fashion to be flat packed." Gabions are mass gravity walls engineered as retaining structures to hold back earth or other solid materials without overturning, sliding or foundation failure.
The modular structure of the walls allows for accommodation of variation of the section as the height increases. The characteristic strength of the units ensures structural and dimensional stability whereas a degree of flexibility accommodates the required ground movement and settlement.
