Rockfall catchment fences

Rockfall catchment fences are systems designed to efficiently intercept and contain falling rocks. These fences consist of key components such as mesh panels, supporting cables, and steel posts. They are characterized by their flexibility and deformability, allowing them to absorb and dissipate the energy generated upon impact. The performance of rockfall catchment fences is influenced by key parameters, including the level of energy absorption and the height of the fence. 

These engineered systems undergo rigorous testing and adhere to international guidelines and certifications. These process ensure reliable and consistent performance against  rockfall hazards.

Through our strategic partnership with Trumer Schutzbauten, a renowned specialist in rockfall protection, we are able to deliver exceptional products and expertise in the field. Leveraging Trumer Schutzbauten’s extensive knowledge and cutting-edge technology, we provide tailored solutions that meet the highest industry standards.


Rockfall Attenuators and Hybrid fences

The primary function of rockfall attenuators is to reduce the energy of falling debris and control bounce heights. These systems normally have no lower bearing ropes and so the material is free to exit the system– with reduced velocity and an altered trajectory.

In the case of a hybrid system, the function lies somewhere between the  catchment and the attenuators barriers. The debris can be contained between the upper and lower bearing ropes. However, the lower bearing rope is strategically positioned downslope, away from the base of the post, for easier removal of accumulated debris.


Certifications and Tests

In collaboration with Trumer, we offer two lines of products, each tested according to specific guidelines. Before 2008, all systems were tested according to guidelines from the Austrian Department of Torrent and Avalanche Control (WLV). Subsequently, the new ETAG 27 guideline of the European Organization for Technical Approvals (EOTA) was introduced in Europe, according to which all rockfall protection fences had to be tested. Since 2019 the ETAG 27 guideline has been replaced by the European assessment document EAD 340059-00-0106 of the European Organization for Technical Assessments (EOTA).
