Coledale Slope Stability

Project Description

Sydney Trains engaged GSS to perform slope stability stabilisation measures at the Coledale Embankment in NSW.

The projects’ objective was to secure over 800m2 of a trackside embankment to ensure no further risk of rock fall and soil movement in the area.

Scope of Works

Ground Stabilisation Systems (GSS) implemented a combination of Tecmat and Stainless Steel Tecco mesh system to secure the embankment.

The mesh was secured with a combination of 11m/10m soil nails and plates.
