Retaining Walls Smithfield
Besser block and concrete sleeper retaining walls for Smithfield homes and yards, drained properly for the low ground along Prospect Creek.
Retaining Walls in Smithfield
Smithfield sits either side of Prospect Creek, and the low ground along the creek line behaves very differently to the higher land towards Greystanes. Down near the water the soil is alluvial with fill layered over it and the ground can stay wet long after rain, while the ridge side is the usual shale clay. The suburb also mixes residential streets with one of the larger industrial estates in western Sydney, so we build both back yard walls and heavy duty yard retention here.
On wet ground the drainage design does more work than the wall itself. We install a slotted agi line bedded in clean aggregate and wrapped in geotextile, add weep holes through block faces and pipe the outlet to a legal discharge point, using a charged or pumped line where gravity will not cooperate. The wall above that is core-filled besser block, concrete sleepers on galvanised H beams, or gabion where free drainage suits the look.
Anything above 1 metre, and any wall holding a driveway, hardstand or the adjoining property, is engineer designed and lodged with Fairfield City Council where approval applies.

Retaining Walls Smithfield FAQs
What is the biggest risk to a retaining wall in Smithfield?
Standing water behind the face. On the low ground near Prospect Creek the soil can stay saturated for days, and saturated soil pushes on a wall with far more force than damp soil does. If there is no agi line, no aggregate zone and no working outlet, the wall is effectively a dam. We design the drainage first on these sites, including a pumped or charged outlet if the fall to the street will not do the job.
How are footings handled on soft Smithfield ground?
Carefully, and usually deeper and wider than on firm shale. On alluvial soils a block wall footing may need to be widened to spread the load, or the wall may be better supported on piers taken down to competent material. Sleeper wall posts get larger diameter concreted holes to compensate for the lower soil strength. The engineer looks at the soil classification and specifies it, and we build to the drawing.
Block, sleepers or gabion for a Smithfield wall?
Core-filled besser block is the strongest per unit thickness and the right call for driveways, hardstands and anywhere a slab bears behind the wall. Concrete sleepers are quicker and better value along a plain residential boundary. Gabion drains itself, tolerates minor ground movement and suits damp corners and industrial frontages. Timber is only sensible for a low garden edge in ground this wet.
Does Fairfield City Council need to approve my Smithfield wall?
If it exceeds 1 metre, retains a driveway or hardstand, sits on a boundary or affects a drainage easement, then engineered plans and an approval are generally required. Below a metre with no surcharge and no easement involvement, many garden walls are exempt development. Prospect Creek flood planning controls can also apply on the low side of the suburb, which is another thing we check before quoting.
How long does a Smithfield retaining wall take to build?
Two to four days for a standard residential wall. Commercial yard walls run longer because of the volumes involved and the need to keep vehicle access open while we work. Wet ground can add time too, since we sometimes have to dewater a trench before the footing can be poured. Whatever the site demands, the expected duration is written into your quote up front.
