Geological hazards/debris flows are typically mobile liquefied landslides containing a variety of material from fine particles to large boulders and tree branches. They are caused by excessive water on slopes, caused by rainfall, glacier melt or similar. The likelihood of geological hazards/debris flows is increased when vegetation and other surface protection has been removed from vulnerable slopes, perhaps by wildfire or clearance. Geological hazards/debris flows tend to be channeled by the topography. Left unchecked, geological hazards/debris flows can damage or disrupt infrastructure, or block watercourses, leading to significant destruction.

Maccaferri has a long history in providing solutions to the 'debris flow' phenomenon. Gabions and reno mattresses are often used to construct weir-like structures. Gabion structures are suitable when access and space is available for their implementation. However, where this is not possible, Maccaferri's debris flow barriers can be considered. Maccaferri debris flow barriers are often installed at the base of drainage basins susceptible to geological hazards/debris flows, or in the channels or chutes in the pathway of potential geological hazards/debris flows. They are unique in configuration and size for each project.

Maccaferri debris flow barriers are similar to rockfall barrier/catch fences but incorporate additional energy absorption elements and variable geometries. Ring nets are ideal in these structures as they have inherent energy absorption capacity, before loads are transferred to the compression brakes.
