Initial situation

A rock and tree fall hazard on an existing property created the requirement for a custom rockfall barrier. The site was narrow (17 m wide), had difficult access and no flat alignments.

Description

The system selected was a 16 m long, 3 m high GBE-1000A-R with pressure posts, drag nets and a gap fill kit.
Below is a list of custom features:

Fixed Post -  no upslope anchors due to proximity of alignment to property boundary
Pressure Posts - no lateral anchors meant barrier could be installed over full property width
Drag Nets - enabled the shorter barrier to have the required deflection to absorb the 1000 kJ energy event
Gap Fill Kit - enabled the  barrier to contour the difficult alignment
