Composed of modular elements in reinforced concrete vibropressed with dovetail joints, they allow you to create a continuous mesh so as to form an articulated complex even on slopes of land that reach 45 °. The conformation of the modules constituted by more than 50% of the surface by holes, allows the growth of the vegetation making the environmental impact very low.
