Rockfall Bolting & Netting

Rockfall netting can be either active or passive.

Passive systems are usually anchored at the top and bottom with rock bolts or dowels. They allow material to fall behind the mesh, which is then gathered at the bottom and removed later.

Active mesh systems are high-tensile mesh systems tensioned into the rock face, preventing surface material from falling. While more complex and generally more expensive to install, they offer significant benefits over passive systems.

There are many variations of mesh systems, with different strength and corrosion protection characteristics.

Selecting the right product is critical and depends on:

• The location and final use of the site
• Compliance with site requirements
• Design considerations, such as allowable mesh deflection when loaded

This is especially important in restricted spaces, e.g., alongside roads or railways, or near buildings or footpaths.
