Stone Strong Retaining Wall Provides Solution at Kawana Lakes

Stone Strong retaining wall under construction at Kawana Lakes.


In early 2015, Concrib was commissioned to design, construct and certify engineered retaining walls at Kawana Lakes on Queensland’s Sunshine Coast.

Due to increased traffic at on Birtinya Island, it had been decided to duplicate Lake Kawana Boulevard. The total distance was just under a kilometre. The $20 million project involved expanding two traffic lanes to four along the Birtinya Island stretch of the Boulevard. It included a bridge roadway.

Local company Shadforths Civil Engineering Contractors undertook the project on behalf of Stockland. They contracted Concrib to retain the bridge roadway embankment.

Concrib engaged Geoinventions Consulting Services to assess the soil parameters and loading conditions in order to conduct the design. Several retaining wall options were put forward. However the preferred solution was a Geogrid Reinforced Stone Strong Retaining Wall with maximum wall heights of up to 4.5metres. Where walls tapered to lower heights, a mass gravity wall was adopted.

Stone Strong Retaining Wall a credit to Concrib’s professionalism.

Referencing the soil profile from extensive borehole investigations, a layer of loose clayey/silty sand up to 3.8m deep was encountered. This necessitated improvement to the ground to be carried out; specifically a reinforced fill mattress to replace the low strength insitu material.

The Stone Strong retaining wall is a credit to Concrib’s experience and professionalism.

The aesthetically pleasing big block retaining wall covered a total wall area of 175m2. It was completed in June, 2015. All stakeholders, including Shadforths and Stockland were suitably impressed with the end result.
