Update: Site 1 of the Road Remediation Works in the Eastern Dorrigo Way, Coffs Harbour

Below is a compilation of few photos from one of the six sites that Specialised Geo has completed for Coffs Harbour City Council in relation to the road landslips & slope remediation works on the MR120 Eastern Dorrigo Way in the Coramba area, west of Coffs Harbour.

In this site, both down the hole (DTH) and top end hammer, methodical approach was applied by the Specialised Geo Team. SG conducted excavation works, drilling and grouting where EVH 1200 mast drill and 12 ton excavator were used. 38mm Hollow Steel bar and 20mm solid galvanised bar were manually installed and grouted. The adaptor, which was fabricated in the Specialised Geo work shop, was used to insert the grout, whereas, Kwik spacers were used on the bar.

Two layers of mesh (Geofabric and GeoBrugg TECCO mesh) were draped on face, using spider plates and nuts that were tensioned to anchors.”
