Introduction
Double Twisted Woven Hexagonal Rock Netting
Woven wire rock netting is supplied in roll format, being produced by double twisting plastic coated galvanised mesh into hexagonal shaped apertures. The fabric of the netting is manufactured from a 2.7mm wire diameter and terminated onto a heavier 3.40mm selvedge wire.

General Information
During demanding soil cutting works, the use of retention structures are frequent. Multiple alternatives are available for these structures, such as those that avoid the loss of stability of the slope (retaining structures) and those that are in charge of guiding loose material that may detach from the rock or slope face. Hexagonal rock netting is used to resolve these types of problems.
In all instances professional engineering advice should be sought to define the most appropriate solution.
