Pelaw Wood Landslip, Durham

Contract Value
Durham County Council
Form of Contract
NEC 3 Short Form

The project comprised the design and installation of slope stability works due to a major landslip which had occurred following adverse weather (February 2016), creating embankment instability and the closure of a popular public footpath and a national cycle route.

Our design and build works comprised:

  • Installation of 112 galvanised soil nails at regular intervals (12m depth) to the Riverside embankment to stabilise the 20m high slope which ranged in steepness from 40 to 46 degrees. The soil nails were installed from the bottom of the slope upwards, to secure the integrity of the working area.
  • Placement of a geocell reinforced earth wall across the face of the installed soil nails.

Access to the site was very difficult, due to the isolated location and narrow access tracks leading to the working area.  Our plant choices were tailored to these constraints and our working method utilised small excavators and dumpers together with specialist soil nailing plant to suit the local topography.

All material deliveries were sent to one central point located approximately 600m away from the working area and brought to site via small dumpers along the narrow cycle track.
