This challenging project involved the stabilisation of a 120m long sloping embankment which had slipped in the central section. To prevent further slippage, it was necessary to install a total of 637 soil nails at 20m in length to the entire slope.




These were installed using long reach excavators and drilling equipment with access being necessary by use of cherry pickers due to the height of the slope. A 3 metre high temporary stone platform had to be installed along the adjacent road to act as access and safe working platform for the workforce and mechanical plant and equipment. The client imposed a restriction that the existing public highway had to remain open at all times to minimise disruption to existing apartments and businesses. This was achieved by a carefully designed traffic management system using three way traffic lights.
Once the soil nails were installed, the slope was landscaped with a selection of pioneering shrubs and wildflower grass seed, existing footpaths and stone walls were dismantled and reinstated with imported fill and topsoil. The existing stone from the walls, which was of historic interest, was reused to refurbish disused steps at one end of the site, which reinstated stepped access to the top of the embankment including ornate balustrade and handrails.
The works were completed timeously, within the Clients budget and with minimum disruption to surrounding residents and businesses.
