(1) Economy. Just put the stone in the cage and seal it.
(2) The construction is simple, do not need special technology.
(3) has a strong ability to resist natural damage and corrosion resistance and adverse weather effects.
(4) Can withstand a wide range of deformation, but still do not collapse.
(5) The sludge between the cage stones is beneficial to plant production and can be fused into the surrounding natural environment.
(6) Good permeability can prevent the damage caused by hydrostatic force.
(7) Save transportation cost. It can be folded and transported and assembled on the site.
(8) Rapid progress, facilitate the rush period: can be multiple groups at the same time construction, parallel, assembly-line.
