RockFall Protection
RockFall Protection
Rockfall debris flow and erosion of soil surface can cause threat to human, and can also damage infrastructure and can also have far-reaching effects beyond the immediate disruption. Therefore, rockfall protection is a key element in the security and safety of humans as well as of the industry. The main objective of rockfall protection is to prevent and control rocks and debris to fall, causing threat to human.
Drapes is often used in protecting the railway track / roads/ property from the rockfalls. The wire mesh is designed to be strong enough to withstand the force of the falling rocks. It allows the rock/debris to move freely inside the mesh when it's properly installed.
The netting mesh literally “drapes” over the rock slope so that falling debris is contained behind the rockfall netting. It is allowed to fall to the foot of the rock slope in a controlled manner. When the expected rock fragments are larger than the aperture of the mesh and smaller than approximately 0.5m in diameter, simple double twist rockfall drapery mesh is a tried and tested cost-effective solution.
Products Used
Surficial Reinforcement prevent the rock detachment and improve the slope surface stability. They also consolidate the shallow surface layer of the slope. These nettings have high strength with minimum deflection to stabilise rock-mass surface layer and contain any detachments.
For higher slopes or debris quantities, when increased loads are expected on the drapery high strength drapery systems are used, which is an engineered combination of double twist steel wire mesh and high tensile steel cables, woven within the mesh during the manufacturing.
These panel are made from single high tensile steel rope, manufactured using twisted cables, woven to form a mesh panel with steel wire knots at each junction. They are used where very high strength and stiffness is required in the face reinforcement.

The combination of a high resistance cable with a soft steel wire makes it a perfect solution for handling both large and small rocks. The HEA panel provides the best performance under static load and stress dissipation to the anchorage points.
