Soil Nailing, Newcastle

Works in preparation for new social housing

Location:  Ouseburn, Newcastle

Client: Robertsons Construction

Project Overview

Robertsons won the contract to build a social housing development on a challenging  site in Ouseburn, Newcastle. The site was flanked by a railway viaduct, a road flyover and incorporated part of a Roman wall.  Pennine was awarded the job of stabilising the steep site retaining slope as part of a temporary works package. The slope characteristics were a combination of sandstone outcrops and loose overburden and work was undertaken in a series of benches.

Pennine used a combination of soil nails and solid bar complete with galvanised meshing and erosion control matting, installing a total of almost 5000 linear metres of nail. 

Pennine used its high torque, feed beam mast with a quick hitch working off the hydraulics of a 20 tonne excavator to reach the highest nail locations. It also deployed its TEI mast and KR 802 to work on the project simultaneously.  

Pennine undertook the nail testing and procured the design of the scheme from Geotechnical Engineering.
