Abstract
Innovative recessed soil nails were used on a conservation slope in Aberdeenshire to help stabilise the slope and provide a
fully green vegetated slope finish. Fifteen hundred soil nails were employed on a 300m long section of the existing unstable coastal slope at
Stonehaven as part of landslip preventive works. Soil nail heads were designed as individual recessed concrete pads set into the slope surface,
buried beneath pre-seeded bio-degradable grow bags and erosion control matting. In this way the pre-existing fully vegetated appearance
was retained as requested by the local residents, planning authority and client. This design provided both local and global stabilisation
of a 40m high slope, sustainability in design, limited disruption to local residents, and aesthetic requirements of this conservation slope.
This paper concentrates on the innovative soil nail head design, not normally used in the UK, to both stabilise the slope and provide full
vegetation cover.
