An important part of a flexible net rockfall catchment fence system is the foundation. Catchment systems have been growing in capacity, able to stop larger and higher energy rockfall events. The trend for foundations has been for them to become larger and more rigid, according to the Association of Geohazard Professionals (AGHP). Members of the AGHP are interested in feedback from owners and engineers experienced in foundation design and their performance in order to synthesize an empirical study of catchment fence foundations and their design. More details can be found at the link below.
Thank you to my old colleague at URS Corporation, Andy Messer for sending me a link to these videos. The are from an Austrian company, Trumer Schutzbauten, that provides products and research related to rockfall fences. The first video is presumably to show the hazards of camping next to hazardous rock slopes…good fun! Click through for the videos.
