£0.5M stabilisation work on Aberdeenshire road nearly complete

crovie 2

Works to tackle a landslip at a north east village Crovie are on schedule to be completed in just over two weeks, Aberdeenshire Council has reported.

A landslip closed the access road to the Crovie in September 2017, meaning it can only be accessed on foot. Since August Geo-Rope has been working to install a mesh system over the affected slope, secured by soil nails, to stop further movement and enable the road above the slip to reopen.

The majority of foundation and drainage works are now complete, as well as the road regrading, strengthening and resurfacing works, and the installation of new surface and ground water drainage systems.

500m² of mesh has been installed over the face of the slope, attached to 170 soil nails installed over the last few weeks, and hollow drainage kerbs are now being installed on the road.

At the same time the existing carriageway is being excavated out with the new road layers laid and compacted. Once complete the asphalt surface will be laid.

The site drainage is split into two individual elements - road drainage and slope drainage. The road drainage will discharge through the existing sea outfall, as the existing pipework did not have sufficient capacity for the additional drainage measures so this has been upgraded. The slope drainage now of comprises six raking drains drilled into the face of the slope. These are connected to a discharge pipe running parallel to the bottom of the slope which enters a drop manhole and then flows through the existing sea wall.

According to the council, site works are expected to take two more weeks, and the remaining tasks include the installation of three drainage gullies, 168m of drainage kerbing, placement of 500m² of asphalt, and the installation of wire and post fence.

The overall project will take eight to 10 weeks, fewer than had initially been anticipated by the council, with the road now expected to reopen to traffic in mid-October.
