32 m Long Soil Nails for Soil Stabilisation

A project, which was awarded to Aarsleff by Esh Construction Ltd on behalf of main contractor Durham County Council required stablising the steepest part of the bankside by installing 92 soil nails between depths of 9 and 12 metres.

In addition, Aarsleff installed some 300 metres of geogrid overlaying to PVC coated mesh. The geotechnical works have helped to restore the river side path and make the area safe for walkers, rowers and cyclists.

The project was particularly complex as the installation was on an extreme slope (53°).
The slope had been left for 3 years by the council, with residents protesting that the right of way had been closed due to the dangerous situation. Standard rope access works could not be employed due to the risk of further collapse.

Aarsleff designed and built a project specific rig attachment and also employed the largest telehandler in the UK with a 25 m reach to tackle and deliver the works.

The extreme gradient at Pelaw Woods meant that extreme care had to be exercised when Aarsleff installed the soil nails since some slope movement naturally occurs before the nails are able to resist the load.
