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)*.

Low Energy Rockfall Barrier Protects Shetland HVDC Substation Construction Site
United Kingdom
The Shetland HVDC link, approved in 2020 after more than a decade of development, is a landmark project that connects Shetland to the Great Britain transmission network for the first time. This critical energy infrastructure unlocks the island’s renewable energy potential, supports the 443MW Viking Wind Farm, and contributes to the UK’s net-zero carbon targets. As part of the project, a 320/132kV substation and HVDC converter station were constructed at Kergord. The works required significant bedrock excavation, resulting in a 6-metre-high exposed rockface formed within the Weisdale Limestone Member. Following excavation, sections of the rockface showed signs of instability, including ravelling and loose material. This created a high rockfall risk to workers operating in the adjacent storage yard at the base of the slope. Without mitigation, falling debris posed a serious safety hazard, making effective rockfall protection essential to maintain safe construction operations.

Railway Cutting Stabilisation at Denby Dale Rockfall Risk Mitigation Solution
United Kingdom
Approximately half a mile north of Denby Dale station, a single-track railway line exits Cumberworth Tunnel into a 14-metre-deep cutting formed within lower coal measure geology. The cutting comprises interbedded semi-competent sandstone alongside weak, friable siltstones and mudstones, creating a geologically variable and inherently unstable slope environment. The cutting slopes are steep, ranging between 45 and 55 degrees, with exposed rock outcrops measuring between 1. 0 and 2. 0 metres in height. Over more than 160 years of exposure, natural weathering processes have significantly degraded the strength and cohesion of the rock mass. This deterioration has increased the likelihood of slope instability and rockfall, posing a direct threat to railway infrastructure, operational reliability, and passenger safety. Recognising the growing geotechnical risk, Network Rail commissioned URS to undertake a detailed site assessment. The objective was to evaluate slope stability conditions and develop an effective long-term rockfall protection solution for this critical section of railway.
