The project involved the design and building of three retaining walls to remediate slips and increase the road width. GeoStabilization’s geotechnical design involved installation of micro piles and construction of a reinforced concrete footing. Once the footing was completed, soil nails and rockfall netting were placed in the embankment.
A Geosynthetically Confined Soil® (GCS®) wall was then constructed and finished with a masonry block facing. All construction works were undertaken under Level 1 Stop / Go traffic control, as the road was too narrow to enable a single lane of traffic with construction machinery.
GeoStabilization completed a design and construct project, based on site extents instructed by the Client, for a retaining wall in 2008.
