Economical. Simply fill the cages with stones and seal them.
Easy to construct; requires no specialized technical skills.
Possesses strong resistance to natural degradation, corrosion, and adverse weather conditions.
Capable of withstanding significant deformation without collapsing.
The silt that accumulates within the crevices between the stones facilitates plant growth, allowing the structure to blend seamlessly with the surrounding natural environment.
Exhibits excellent permeability, thereby preventing damage caused by hydrostatic pressure.
Saves on transportation costs; the cages can be folded flat for transport and assembled on-site.
