Rock fall Netting – Slope And Asset Protection

An Introduction To Rock Fall Netting

Rock fall netting is a type of passive protection system used in geotechnical engineering to mitigate the risk of rockfall hazards. It consists of steel wire mesh or cable nets that are anchored to the slope or cliff face to prevent falling rocks from reaching the ground below. The netting is designed to absorb the impact of the falling rocks and prevent them from causing damage or injury to people and infrastructure.

Rock fall netting is typically used in areas where there is a risk of rockfall, such as highways, railways, mining operations, and urban areas located near steep slopes or cliffs. It is a cost-effective and practical solution for protecting people and property from the hazards of rockfall.

The design and installation of rockfall netting require a thorough understanding of the geological conditions and the potential hazards in the area. Proper installation and maintenance of the netting are crucial to ensure its effectiveness over time. Rock fall netting has proven to be an effective method for mitigating rockfall hazards and has saved lives and prevented property damage in many situations.
