When filling gabions, choosing the correct filling rocks is important. Quarried angular cut rocks offer the best interlocking features plus they are the most common rocks for filling retaining wall gabions. Rocks for 3 x 3 in square mesh gabions should measure 4 to 8 in. (1.3 tons per cu yd / 2600 lbs)
Its also important when machine filling to pay close attention to voids and for the best presentation and a natural stone wall look, hand pack the rocks on the gabion's front face.
Rounded river rocks or polished deco rocks are not recommended for stacking gabions in retaining wall projects but ok for decorative landscaping projects.
When using the more expensive deco rocks, you can save money by adding an extra panel near the front face to create a narrow filling compartment for facing and complete filling the remainder of the basket with building rubble such as crushed concrete or broken bricks.
In order to prevent bulging of the basket, bracing wire should be used to create a windlass at the 1 ft and 2 ft filled levels on 3 ft tall baskets and 1/2 way on 1.5 - 2 ft tall baskets.
Baskets should be laced together using lacing wire and slightly overfilled to accommodate settling when gabions are stacked .
