ARRTERR - PRE-ASSEMBLED SYSTEM FOR REINFORCED SOILS WITH INCLINED RENDERABLE FACE
Reinforced earth is a geotechnical system often used in the construction of earth embankments, for construction works
stabilization and containment of the counter-bank and underscarp of slopes, in road, railway and hydraulic areas;
on ski slopes; rockfall valleys and naturalistic engineering works.
Compared to the traditional elements of a reinforced earth construction, which provide for the separate laying of the
constituent elements such as the front facing, the fine retainer and the planar reinforcements, the ARRTERR system is already
pre-assembled, with an inclined face between 50° and 70°, already joining together:
• Planar structural reinforcements in polymeric double twist hexagonal wire mesh;
• The fine retainer in 100% natural, biodegradable anti-erosion biomesh with open mesh;
• The front facing and the base are in electro-welded Znal alloy mesh, edged and hinged by points, so as to form a rigid and articulated front element.
• The planar reinforcements in double twist wire mesh guarantee high standards of stiffness and at the same time absence of deformation due to creep;
• The front facings being covered in znal alloy have high durability and a good visual impact;
• ARRTERR is pre-assembled and designed in "safety", to avoid injury or cuts to workers on site;
• The up to retainer in open mesh bionet allows effective anti-erosion retention and at the same time is effective in allowing hydroseeding or other greening techniques to take root;
• The ARRTERR system is supplied pre-shaped and made to measure according to the project specifications, with angles predetermined by the project by inserting triangular brackets;
• Being pre-assembled, the ARRTERR system allows you to reduce processing times, costs and risks;
• The predetermined geometric modularity makes ARRTERR also suitable for the creation of mixed works with other techniques (for example together with the hexagonal mesh gabions);
• ARRTERR reinforced earths are made in compliance with the provisions of the Cons Guideline. Sup.
LL.PP. 69/2013 and are equipped with CE marking.

ARRSYSTEM - PRE-ASSEMBLED SYSTEM FOR REINFORCED SOILS WITH VERTICAL FACE
ARRSYSTEM is a pre-assembled system of "mixed" reinforced earth (which combines the characteristics of gabions in
hexagonal wire mesh and that of reinforced earth ARRTERR), is a modular system for stabilization
of slopes, embankments and/or embankments; externally covered with stones.
The system consists of a frontal gabion structure with vertical facing in double twisted wire mesh.
sion, pre-assembled with a planar reinforcing element having the same characteristics. The structure a
gabion will be filled with stones during the application phases, while the reinforcing planar structure will be
covered and compacted with suitable soil.
The main application areas of ARRSYTEM reinforced earths are found in:
• Construction of walls, embankments, retaining embankments and stabilization for protection
geo-hydrological and structural works (roads, bridge pillars, railway embankments), in particular
in those interventions where it is essential to reduce space by exploiting verticality and have a
effective drainage system;
The main application advantages of ARRSYSTEM vertical facing reinforced earth:
• The verticality of the front gabion allows to reduce the overall dimensions of the work compared to a traditional reinforced earth with inclined face;
• The front gabion allows for a good drainage action thanks to the presence of stones;
• The presence of the front gabion allows the soil placed behind to fill the embankment to be retained, without the need for hydroseeding or greening of the work (in this case, it is possible to envisage inserting vegetative pockets or cuttings in the gabion);
• The fact that it is a pre-assembled and modular system allows for reductions in installation times, costs and risks;
• The ARRSYSTEM system is supplied pre-shaped and made to measure according to the project specifications;
• The predetermined geometric modularity makes the ARRSYSTEM system also suitable for
creation of mixed works with other techniques;
• ARRSYSTEM reinforced earths are CE marked.

GABIONS AND REGREENABLE GABIONS - RETAINING WALLS AND HYDRAULIC PROTECTION WORKS
The double twist hexagonal wire mesh gabions are box-like structures filled with stones, which act
as gravity support structures, with high water drainage capacity, exploiting the cohesion between
stones and wire mesh.
The main fields of application of gabion structures in hexagonal wire mesh can be found in:
• Construction of retaining walls on the counter bank and under scarp for the consolidation of landslide, road, railway and architectural slopes;
• Realization of both longitudinal and transversal hydraulic protections (for example hydraulic bridles);
• Implementation of low-cost engineering works

The main application advantages of double twist wire mesh gabion works, compared with other types of
works:
The gabions produced by Arrigo Gabbioni Italia srl comply with the Cons. Sup. LL.PP. 69/2013 and with
CE marking.
• They are able to accept deformations and displacements, even important ones, without compromising their static functionality;
• Thanks to their porosity, they perform an effective draining action and do not hinder the circulation of the groundwater, thus avoiding the formation of hydraulic pressure behind the embankment;
• Being modular works they can be integrated with other types of low-impact artefacts for the realization of Naturalistic Engineering works;
• They can be easily re-greened by inserting cuttings and/or vegetative pockets
(Greenable gabions).

GABIONS WITH HULK ANCHORS
Arrigo Gabbioni offers an innovative system of Tirantati Gabions with application of Hulk insertion ground anchors.
The proposed system - effective, rapid, safe, made with highly durable materials and with certified performance - allows you to increase the safety coefficient of the gabion work by reducing its footprint and canceling the effect of any sliding surfaces behind it wall, without the need for further excavations and excavations, without resorting to the use of specialized machinery such as drilling machines or the use of grout or cement mortar.
This is possible due to the cone of resistance generated by the certified Hulk ground anchoring system, an engineered system, optimized on the basis of experimental data and thirty years of experience in the field, which can be sized according to the project needs in all its components.
Application areas
The main application areas of tie-rod gabion structures with Hulk ground anchors can be found in:
• construction of counter-bank and underslope retaining walls for the consolidation of landslide slopes, road and railway embankments or architectural solutions;
• creation of both longitudinal and transversal hydraulic protections (for example hydraulic bridles);
• realization of naturalistic engineering works.
Advantages
The particular technical and application characteristics of the combined system made up of gabions and Hulk percussion anchors allow, in many application areas, to obtain a notable series of advantages compared to the use of other systems:
⦁ Greater installation speed
⦁Higher strength than any other percussion anchor system on the market
⦁ Specific engineered shape of the moving head to facilitate insertion and increase the cone of resistance
⦁ No anchoring depth limit
⦁ Lightness of the components
⦁ Leak test performed directly during installation
⦁ No disturbance in the surrounding land;
⦁ Does not require:
- heavy and/or expensive metal structures inside the gabionade;
- further excavations or excavations, drilling;
- use of drills or drilling machines;

RINVERDIBILI BIOGABIONS – RETAINING WALLS AND HYDRAULIC PROTECTION WORKS
The greenable Biogabions in double-twisted hexagonal wire mesh perform the same function as the
classic double twist wire mesh gabions, for soil defense and geotechnical engineering, in
more, the fact of being able to contain within them a vegetative pocket that can be green again, allows the work to have
a more effective and rapid insertion in areas of greater naturalistic interest and consider the
Biogabion as naturalistic engineering.
The vegetative pocket, positioned inside the Biogabion, and with measures defined during the
design, allows you to have greater protection from the elements and from possible impacts
processing stage on site
The main application areas of Biogabion structures in hexagonal wire mesh are found in:
