The Best Gabion Walls In Adelaide By Aus Construction

    Old-fashioned wire gabions are the best solution for soil erosion issues and are best for retaining purposes. Our gabion wall builder in Adelaide installs gabion retaining walls in any small, large, residential and commercial projects.

    The gabions are solid but flexible and accommodate ground movement. These retaining walls are porous and eliminate water pressure that builds up behind the wall. Australian Construction installs them fast at an affordable cost since footing or curing is not needed, and they are long-lasting.

    ​We also install retaining walls in suitable areas. Our skilled team laces the strong, galvanised steel mesh panels together and stabilises them with posts inside the ground. They form a thinner profile and are utilised for more aesthetic purposes in places where stabilisation is not necessary.

    Building a gabion wall

    Gabion walls look wonderful and last a lifetime. They are a great method of constructing garden beds, retaining walls, rock wall features, seating and several landscape features.

    Gabions describe wire mesh containers full of rock, creating gravity walls. The internal fill’s weight offers the necessary strength to sustain earth retention pressures. Gabions are affordable and reliable for small and large projects.

    There are two kinds of gabions; weld mesh cages or woven wire baskets. Civil projects mainly use woven baskets to save costs, while weld mesh cages present high aesthetics and sturdier panels and are mainly found in architectural projects.

    Main benefits of using gabions

    • Long-lasting
    • Maintenance is not necessary.
    • Free drainage enables water to pass through the building instead of accumulating behind it.
    • Architectural appeal
    • The modular design is simple to build
    • Limited footings needed
    • Vandal and graffiti proof

    How we build a gabion wall

    Step 1: wall and preparing the base level

    The Australian Construction team uses a compact road base since it is more appropriate for constructing gabion walls, whether the structure is gabion fences, retaining and other gabion features. But for areas with high water flow, we need more preparation. 

    Step 2: building a gabion wall, assembling and installing

    We assemble the gabion cages to ensure the bracing wire’s correct installation. It ensures when we are building your gabion walls, they remain very straight and have a perfect look after the completion of your project. Our gabion wall builder in Adelaide then links all the gabions together, creating a single structure.

    Step 3:  using geo-fabric to construct a gabion wall

    To ensure that the gabions still look attractive in future, we suggest installing our superior non-woven geo fabric material behind and under when we are constructing gabion walls.

    Geo fabric facilitates water flow through the gabion structure (behind the wall; there is no pressure accumulation). However, soil particles are contained.

    Step 4:  building a gabion wall and choosing the gabion rock

    Opt for stone walls like bluestone, basalt, granite, etc., in 100-200mm. These kinds of stones do not disintegrate with time, look lovely, and have angular forms for stacking compactly inside the gabion.

    They are easily accessible through landscape yards and cost less than decorative stone, and are ideal for constructing gabion walls.

    Step 5:  Take time to construct a gabion wall

    It is easy to assemble and build gabions. Our expert team take time to fill the gabions with stone. It would be best to let our gabion wall builder in Adelaide examine the facing panels frequently to ensure they are even and straight.

    To avoid gaps, we pack the stone tightly. The bracing wire prevents bulging of the facing panels. We pack the cages in a sweeping arrangement and spread the stone from one cage to another. This procedure keeps the end panels straight. 

    Main mistakes in gabion building


    It is crucial to reduce big spaces inside the cells when using stone to fill the gabion baskets. The reason is that with time, settlement can happen, and if, for instance, the stones have large spaces between them when there is heavy rainfall, the stones shift as the wall settles. 

    This occurrence compromises the wall, and the gabion mesh starts to change shape and gives way at its weakest area, the centre of the face. It results in bulging and more significant pressure on the weld joints.

    In Adelaide, our gabion wall builder continuously checks for big voids when hand filling or machine filling the baskets. It consumes more time during building but saves you a significant amount of money and time in the future.

    Geotextile separator fabrics

    We advise using a geo-textile fabric separator to the gabion wall’s underside and rear wall. Geo-textiles present a non-woven permeable material we mainly use in building gabion retaining walls to avoid fine soils from trickling through the gabion baskets. 

    Incorrect stone choice

    We cannot use any stone to fill gabion baskets. The angularity and grading of fill are among two most vital elements to consider when selecting gabion stone. The stones grading should have a diameter of between 100-200mm. We tighten it to 80-150mm if the grading’s control is tight.

    It will not contain stones whose size is smaller compared to the mesh. The non-frost flexible quarried stone is usually angular, and we prefer it for filling since the interlock is exceptionally tremendous and there are minimal voids.  

    Filling the gabions with extracted rock or stone from the present site is not usually advisable since it may lack suitable qualities. For instance, if the stone is sensitive to frost during the winter months, the fill starts to disintegrate, leading to voids.

    The gabions’ weight makes them buckle on walls more than 1m high, making the structure and wall unsafe.

    The bulge

    The bulge mainly occurs on big retaining walls because of the absence of internal bracing ties. It causes the mesh face to deform, resulting in the unattractive ‘bulge.’

    We install internal windlass bracing ties at each 1/3 and 2/3 of the basket. It entails lacing tying wire (provided as standard), central to every cell. It spans two meshes on the rear and front faces. 

    We can temporarily wire scaffold tubes or timbers to the outer faces during filling. It works as a shuttering to avoid bulging, and we remove it after completion. Secondly, we ensure that we use the suitable grading of stone and minimise the voids. Thirdly, we give you the option of choosing a thicker mesh, either 4mm or 5mm.
