A steep natural slope at the boundary of residential gardens at Peth Head had suffered crest erosion and slipping over many years.

Patrick Parsons acted as project manager for the stabilisation works which involved a combination of 5-8m long soil nails, Platypus ground anchors and erosion matting on the upper part of the 300m long slope.

The soil nails were typically 8m long and installed at 15 degrees to the horizontal, utilising a staggered grid at 1.5m spacing.

Each nail was capped with a faceplate to hold the erosion matting in place. In view of the height and steepness of the slope all works were carried out via roped access.
