ERDOX JUNIOR represent the most valid alternative to
Gabions. Optimal for rapid and safe “urgency” works. ERDOX JUNIOR structures are in fact used for: soil support
works, consolidation and stabilization of small landslides,
consolidation of scarp roads affected by superficial gravitational failures, erosion control systems, riverbank and
canal banks. The technology is based on the use of singleanchoring metal structures, widely defined as “umbrella”.
These barriers guarantee an optimal corrosion resistance
as they are supplied with hot dip galvanizing EN 1461 with
double twisted mesh Galfan protected and steel ropes
with eutectic alloy Zn – Al5% class A galvanizing (UNI EN
12385-2-4, UNI EN 10244-2, UNI EN 10264-2).

Erdox Junior is a pyramidal isostatic structure. The frontal cross-shaped structure consists of a 90x90x3 mm square tubular profile beams in the “BASIC” conformation or 90x90x6 mm square tubular profile in the “REINFORCED” conformation, in support
of a coupling of double twisted meshes. The stresses are transmitted to the foundation through a tubular profile connected to
the central node and a system of steel bracing cables. The soil retaining is made through a double twisted mesh positioned
inside the structure, with the function of load distribution on the main cross element of the structure, combined with a MacMat , positioned externally to the cross, with the function of retaining the thin soil and mitigating the visual impact. The coupling between the central point and the upstream tubular profile has been designed to ensure a slight three-dimensional rotation of the front panel, consequently adapting the structure to the conformation of the soil and to the geomorphological variations that develop over time without any unexpected stress being transferred to the structure. The anchoring of the Erdox Junior can be made with different technologies to counteract the horizontal forces such as foundation tierods, self‐drilling bars,
precast reinforced concrete/galvanized steel plates according to the project specifications.
