Rockfall Netting

Rockfall Netting

Protecting roads, buildings, and other structures directly at the tip of man-made rock debris or natural cliffs is a major challenge for engineers. Falling debris and rock may be due to vegetation action, thermal expansion, wind, cold and thawing, hydrostatic pressure, and seismic action causing rock degradation.


The slope protection netting is anchored to the slope with rock anchors. The rock anchors are steel rods set into grouted, small diameter holes drilled to specific depths into the rock. The rockfall netting adapts to the topography and can be designed to prevent shallow slides, deformations, and rock dislodging, thereby protecting the life and property below. 


Rockfall mesh has been used around the world for many years and has proven to provide strong, durable, and economical rockfall protection. On moderately steep slopes, or on slopes where some vegetation may be growing, the mesh should be placed as close to the slope as possible. On very steep and/or near-vertical slopes, the mesh must be secured at the top of the cliff, but not at the bottom, thus allowing rocks and debris to fall into a collection trench at the bottom of the slope. A key factor is to have a secure and continuous anchor point at the top.


High tensile steel wire is ideal for creating fallen rock draperies because it is flexible in all directions and will not come apart even in the event of some wire breakage. It also does not inhibit the regeneration of vegetation, allowing the slope to return to its natural state after restoration.


Applications


High Tensile rock mesh is commonly used for a variety of specialized geotechnical applications including slope stabilization, rockfall protection, and surface protection applications.


Features


Adapted to the local soil and rock static requirements, the HIGH TENSILE ROCKFALL MESH can be anchored in accordance with our dimensioning concept with commercial soil or rock nails. The main anchors of the system are installed in a grid typically from 6.6 to 16.4 ft (2.0 to 5.0m)horizontal and vertical spacing. 


Actual spacing depends upon the results of site analysis and modeling. Anchor consists of commercially available steel bars ranging from 1.0 to 1.25 ft (25 to 32mm). Self-drilling grout injection anchors are also permitted. Additional anchors may also be used to provide added support at boundaries and in low points and hollows.
