We design, engineer, and construct gabion retaining walls for residential, commercial, and civil projects across Sydney. Wire cages, quality rock fill, engineered foundations. Walls that retain, drain, and endure.
Gabion walls combine three things most retaining systems struggle to deliver together: significant mass for gravity retention, excellent free-draining properties, and the ability to flex with ground movement without cracking. That makes them uniquely suited to demanding sites.
METCON constructs gabion retaining walls using Galfan-coated wire mesh baskets filled with quality rock, built on engineered footings with proper base preparation. Every wall is designed by a structural engineer with cage sizes, rock specification, and batter angles matched to the site.
Whether it's a residential landscape feature, a civil drainage channel, or a major earth-retaining structure on a development site — gabion walls offer a practical, durable, and visually distinctive solution.
Every gabion wall follows our structured five-step process. Designed by engineers, constructed with quality materials, documented throughout.
We assess the site, measure retaining requirements, evaluate soil and drainage conditions, and determine the best gabion configuration for the application.
A structural engineer designs the gabion system — cage dimensions, batter angle, footing requirements, and rock specification matched to the retaining height and loads.
The foundation is excavated and prepared to specification. Geotextile is laid, base cages are positioned, and levelling is verified before rock filling begins.
Wire cages are assembled, braced, and filled with selected rock in controlled layers. Internal tie wires maintain cage shape. Each tier is completed before the next.
Engineer inspects the completed wall. You receive design drawings, construction photos, and certification for council, strata, or project records.
Structural design, quality materials, documented construction, and engineer certification. A gabion wall that performs for decades.
Whether it's a residential landscape wall or a civil retaining structure — send us the site details and we'll design and price a gabion solution. Clear quoting from experienced builders.
