Gardenstown stabilisation work "progressing well"

Work to stabilise the landslip that led to the road closure in Gardenstown is progressing well, according to Aberdeenshire Council.

Bam Ritchies has now drilled 30 soil nails into the face of the affected slope using the mobile drilling skid rig.

The nails will secure the Tecco mesh slope stabilisation system over the affected area. So far 30 nails have been drilled with a further 90 soil nails to be drilled over the next few weeks.

Upon reaching bedrock the boreholes in the face are continued to a minimum depth of 3m into competent rock and the nails are bonded into the bores with grout.

Around 40t of loose rock and soil was removed, along with vegetation, prior to work on the slope face starting.

Soil nailing operations began on 13 May and are expected to take 23 working days to complete.

The road was reopened full time at the end of April while Bam delivered the preferred interim solution, designed by Atkins, to stabilise the slip, protecting the road and properties below.

Further road closures may be necessary to accommodate works on site which pose a potential risk, such as the movement of large rocks or plant. These closures are governed by a bespoke traffic light system, which will also operate should movement of the slope above pose a risk to traffic.

Road users have been advised to obey any red light until an inspection is carried out by site staff and the traffic light system reset. Once the mesh work has been completed the lights will be removed.
