Rockfall Netting

Rockfall netting is typically used in both simple drapery systems and in a variety of specialist geotechnical and engineering applications including slope stabilization, rockfall protection and surface protection applications.


It is a highly efficient mesh combining ease and flexibility of use with unsurpassed cost-effectiveness. Used around the world for over 60 years, rockfall netting mesh is proven to offer robust, long lasting and cost-effective rockfall protection. On moderately steep slopes, or those where some vegetation may grow, the mesh should be kept as close to the slope as possible. On very steep and/or near vertical slopes, the net must be anchored at the top of the cliff, and left unanchored at the bottom, thereby allowing rocks and debris to fall into a collection ditch at the toe of the slope. A key factor is to have a safe and continuous anchorage at the top.


Rockfall netting consists of double-twisted wire mesh made from wire which is zinc coated before being double-twisted into mesh. Fasteners, lacing wire, and stiffeners are produced from zinc-coated wire.
