Gabion construction by Polyfabrics Australia
Gabions and mattresses are made of double twisted hexagonal wire mesh
and filled with rock. Gabions and mattresses arrive on site as flat as units in bundles.
The walls, dividers, lid and base are expanded and assembled by lacing the loose edges.
Lacing can be achieved by either conventionally using lacing wire or using steel rings.
Steel rings are fastened using a specialised pneumatic tool - Lacing Tool.
Lacing Tool - used with galvanised or stainless steel rings. Available for hire or sale.
Construction methods and site training provided if required.
Applications includes mines roads, road & rail embankments, flood plains & water
courses and permanent or temporary works.
Permeable improves flow characteristics, designed for water velocities of 5m/s. Reduces
and eliminates expensive drainage systems.
Completed gabions filled with hard durable rock (e.g. Basalt or Granite), with a rock
grading between 100mm to max 250mm in size (or max 2/3 depth or mattress).
Using the lacing tool, productivity increases by 60% then using the conventional lacing
method.
Proven safe and beneficial to the environment plus it blends with the natural environment.
