Protection against falling rock masses with extremely high energy levels is not feasible with rockfall barriers. Maccaferri has therefore developed rockfall embankments made of Terramesh, which are able to withstand extremely high energy levels. Even though the overall size is comparable with that of the traditional rockfall barriers, these easily withstand a multitude of impacts with very high energy levels, without any appreciable deformation or requiring extraordinary maintenance. In addition to this, the embankments have the enormous advantage of having a negligible visual impact. The current experience allows for the design and construction of embankments with a height of up to 20 m, with facings sloping up to 70°, and with a resistance of not less than 20,000 kJ (20 GJ).
