We have recently completed a soil nail slope stabilisation project near the village of Aldclune, on the north bank of the River Garry, in Perthshire.
The work-site was beside the railway line on an embankment and an area of flat ground where our team removed woody vegetation using chainsaws and chippers to allow the soil nailing process to be carried out. The vegetation comprised Hawthorn, Blackthorn, Birch, Elm and Cherry trees.
Following the vegetation clearance, a soil nailing team moved onto the site to drill soil nails through a corrugated pipe passing through the Gabion Baskets that have previously been installed, thus providing an additional level of protection. The soil nails that we installed are sacrificial (i.e. left in place) hollow bar and drill bits. Grout was pumped down the hollow bar as the bar was being drilled; this is one of many methods of soil nailing.
