METAL LINERS

IN DOUBLE-TWISTED HEXAGONAL WIRE MESH

Metal liners produced by Arrigo Gabbioni Italia S.R.L. are specifically designed to be used as bank protection for rivers and streams. Their characteristics are: parallelepiped shape, notable breadth and minimal thickness (16-23-30-50 cm). Liners come with or without pockets which form a diaphragm cell structure. Metal liners may vary for: size, length, width and mesh. Structures are formed of 8x10 or 6x8 hexagonal mesh.

 

PROTECTION OF BANKS AND CANALS

River and stream banks are typically protected using flexible consolidation barriers. Their flexibility allows the structure to adapt to the slopes of the banks and form a single and compact block, also with a draining function.

In this case, metal liners represent metal structures in thin woven mesh which can cover extensive stretches of banks. The liners also feature pockets to be filled with stones. These clusters create a robust yet not extremely rigid structure. This flexibility is essential, as the structure must adapt to the morphological changes of the slope to which it is applied. In fact, erosion or physiological movements continually modify river banks. Therefore, a compact and rigid structure would eventually lose grip and begin to produce excessive resistance.

The liners can also be combined with waterproofing systems (e.g. membranes), where a waterproof coating and eventual re-greening are required.
