What is Gabion Wall?
Build of cuboids metal cages or baskets made up from a square grid of steel fabric, usually 5 mm in diameter and spacing 75 mm
This baskets are usually 2m long and 1m2 in cross-section, filled with stone particles. A central diaphragm fitted in each metal basket divides it into two equal 1m3 section and adds stability
During construction the stone-filled baskets are secured together with steel wire (2.5 mm in diameter).
The base of a gabion wall usually about 0.5h.
