A retaining wall is only as good as what sits beneath it. We handle all excavation and footing work in-house, built to engineer specifications and ready for the wall system above.
Most retaining wall failures start below ground. Inadequate footings, poor compaction, missing drainage, or excavation that destabilises adjacent soil — these are the things that cause walls to lean, crack, and eventually fail.
We take the ground works seriously because we know what happens when they are done poorly. Every retaining wall project we build starts with proper excavation to design levels, footings poured to engineer specifications, and drainage installed before the first sleeper or block goes in.
Whether the job calls for a mini excavator on a tight residential site or a larger machine on an open commercial block, we have the equipment and the operators to do it right.
The footing type is specified by the structural engineer based on the wall system, retained height, soil bearing capacity, and site conditions.
Continuous concrete footings that run the length of the wall. The standard footing type for concrete sleeper, timber, and block retaining walls. Width and depth are specified by the engineer based on loading and soil conditions.
Individual concrete pads at each post location. Used for post-and-sleeper wall systems where the structural load is concentrated at the posts rather than distributed along the wall length.
Drilled concrete piers that extend to stable ground or rock. Required on sites with poor bearing capacity, reactive soils, or where the wall supports significant loads. Posts are cast directly into the pier or connected via brackets.
Site access, soil type, and proximity to existing structures determine the excavation approach. We adapt to the conditions of each site.
Water is the primary enemy of retaining walls. When water accumulates behind a wall, it creates hydrostatic pressure that the wall was not designed to resist. The result is bowing, cracking, and collapse.
We install drainage behind every retaining wall we build. The standard system includes ag-pipe wrapped in geotextile fabric, laid in a gravel bed behind the wall base, and connected to the stormwater system or a suitable discharge point.
We handle the entire process from excavation and footings through to wall construction and site clean-up. Get in touch with your project details for a clear quote.
