Gabions & Mattresses Deliver 'Unsurpassed Flexibility and Strength' for Carindale Project.

Overland flow management and containment of flash flooding is a requirement that must be addressed by developers of urban and commercial sub-divisions. A recent example of this is a retention basin and weir that provides flood control for a subdivision at Scrubb Road, Carindale (in Brisbane). The developer was Monkton Developments.

Landplan Engineering Supplies was able to provide their client with a complete supply and installation package for the gabion and mattress structure. Gabions and mattresses are options utilised mainly in erosion control and weir structures due to the unsurpassed flexibility, strength and ability to handle high velocity turbulent water flows. Whilst the installation was reasonably straight forward, we had to work with a 50mm tolerance to ensure the spillway was level throughout the cascade steps. This required careful monitoring of the excavation across the full length of the structure with constant checking and adjustment of the earth works. Whilst this process was very slow and time consuming, the result was well worth the effort. Crest Length: 30 metres Height: 2.5m.
