For Gabions Applications

The performance of gabion structures depends not only on the type and quality of the gabion units specified but also the gabion filling materials chosen for both their mass and aesthetic appearance. In all events, the specified fill must be hard, durable and non-frost susceptible. Typical stone types indigenous to certain areas are illustrated below.

Quarried stones that are angular are the preferable fill with good interlock.

Crushed concrete although angular, tend to become rounded. It does have greater interlock than rounded stones, therefore 4mm wire diameter in Galfan coated or 3.8mm wire diameter for PVC welded wire mesh should be specified.

Rounded stones have a smoother face, therefore lower interlock potential, which can result in increased deformation of the unit’s face. Welded wire mesh gabions should be specified in 4mm or 5mm wire diameters for Galfan coated or 3.8mm wire diameter for PVC coated units to overcome this along with attention to detail during the construction process.

Blocky stone or flat stone when machine filled can result in large voids, which may result in settlements. Care should be taken when machine filling to minimise large voids.

Ideally, all gabions should be fair-faced (hand packed on the exposed faces). Where the cost of blocky stone or flat stone is high, the gabions can be filled with two types of fill: a blocky stone or flat stone for the exposed face with a cheaper quarried stone fill behind.
