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.

CEBU TRANSCENTRAL HIGHWAY
Philippines
The Cebu Transcentral Highway is located in Barangay Cansamoroy, Balamban, in the province of Cebu, and is approximately 33 kilometers long. It’s one of Cebu’s most ground-breaking transportation development as it makes land travel to several destinations in Cebu’s central and northwestern regions faster and easier. However, certain sections in Balamban Transcentral Highway imposed danger to the infrastructure and motorists passing by. Contractors and designers sought to prevent hazards such as falling rocks or boulders, landslides, and debris flows during heavy rainfall or typhoons.

Gabion Defense - Cajuca East Corridor
Given the events following the El Niño phenomenon in 1998, the Nazca Valley has been affected by river overflow and ravines. The high vulnerability to overflowing on the right bank of the natural drain in the Cajuca area of the Nazca district poses a latent danger to the entire population of the populated centers Cajuca I, II, and Buena Fe.
