Rockfall Barriers
Catching rocks before impact damage
Maccaferri Rockfall Barriers (or Catch Fences) are designed to catch falling rocks and boulders before they fall onto infrastructure, mine haul-roads or other developments.
Our wide portfolio of rockfall barriers range from 35 kJ/H=1.35m to 9000 kJ/H=8m.
Maccaferri Rockfall Barriers are supplied in a "kit" form. All components are supplied in the kit in accordance with EAD 340059-00-0106 or EAD 340089-00-0106, including main nets, poles, base plates, energy dissipation devices, wire ropes and all accessories.
Our rockfall barriers are CE marked, guaranteeing rigorous quality control.
The anchors to connect the barriers to the ground are supplied on request and according to a specific design considering the ground conditions.
Maccaferri's engineering know-how leads to the design and successful testing of cost-effective solutions.
Our barriers are among the best in the field in terms of performance (high residual height after impact and low deformation upon impact).
Our barriers are easy to install, the design being made not only to achieve high level performance but also to facilitate the installation process for workers (pre-assembled panels on the posts, climbing steps on the posts, system opening of the curtains)*.

CANTERA ZIORDIA
The Ziordia quarry has an orography formed by limestone rock, with steep slopes as a result of quarrying, and potentially unstable large blocks. The company CRS Ingeniería contacted Bianchini Ingeniero to analyse the situation and possible solutions, and subsequently the company Inaccés Geotècnica Vertical also intervened. One of the main risks was the blocks that could fall from a 40-metre-high, 15-metre-wide mochón, located on one of the quarry's usual passageways. This represented a potential risk for the installations and the workers themselves. Therefore, a series of actions were carried out to stabilise these blocks and protect the area.

LÖTZGALERIE
Austria
The busy Inntal motorway from Arlberg towards Innsbruck is a very important west-east connection. For the construction of a new gallery below steep rock faces, ASFINAG has planned 3000 kJ rockfall protection nets. These barriers will protect the construction site and the motorway during construction.

MITIGATION MEAURES NEAR PANGI BRIGDE APPROACH, HIMACHAL PRADESH
India
The landslide of Pangi nallah on the old Hindustan-Tibet road (bottom road) at NH-22 at KM 373. 05 causes inconvenience to the civilians, Army, BRO, and ITBP Officials. The major problems on the site were rockfall / falling debris, surficial instability, erosion and subsurface water flow, which poses a continuous threat to the people and traffic flow along the section of NH 22 at KM 373. 05. Therefore, the site required suitable mitigation measure for a smooth and safe traffic flow. It was observed from the engineering investigations that the existing road width near Pangi nallah varies from 3. 5 to 4 m. Most of the road was damaged and the total stretch covered by the landslide was about 130 m. The hillside height is about 1000 m, whereas the valley is approximately 60 m deep with a steep slope angle of 60-80 degrees.
