Early 2014 following a period of heavy rain, subsidence and scouring of the land within Slade Park was observed on the northern edge adjacent to the pedestrian pathway.
Slade Park has a known history of instability extending back to the early 1990’s.
The embankment stability failure was a noted as a repetition of stormwater flows into a concentrated area over a number of years.
Cadifern was engaged by Wollongong City Council in April 2016 to carry out retaining wall and embankment stability works in the area.
The project involved early preparation works including reshaping the slope, and the construction of a concrete footing for the retaining wall.
The retaining wall consisted of two levels of Rocla Mass Blocks across the length of the wall (Approx. 50m), backfill works involving geofabric and drainage behind the blocks, followed by backfill and compaction. To finish the project Cadifern constructed a 2.4m wide footpath on top of the newly constructed wall and the installation of a Monowills balustrade.
Cadifern proudly completed the project ahead of program, meeting all the relevant legal and other requirements and ensuring that our final product was not only of high quality but visually pleasing for the community.
