Soil Nails for Pelaw Woods slope in Durham

Aarsleff Ground Engineering began work at Pelaw Woods in Durham on the 24th October 2016 and completed the project on the 9th December 2016. The project, which was awarded to Aarsleff by Esh Construction Ltd on behalf of main contractor Durham County Council required Aarsleff to stabilise 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. Aarsleff’s 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 25m 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. Despite the difficult location, Aarsleff Ground Engineering delivered geotechnical excellence on this project where others had failed to produce a safe plan for the works.
