Frequently Asked Questions About Concrete Retaining Wall in Drysdale
How much does a concrete retaining wall cost in Australia?
A concrete retaining wall in Australia typically costs $50–$150 per square metre supply and install, depending on wall height, reinforcement, and site access. Reinforcing bar and formwork add to material costs, and drainage behind the wall is essential. A modest 10m² wall usually falls between $500 and $1,500.
Does a concrete retaining wall need drainage?
Yes, every concrete retaining wall needs drainage behind it to relieve water pressure that can crack or push over the wall. Standard practice uses slotted ag pipe wrapped in drainage gravel, running along the base and out to a discharge point. Skipping drainage is one of the most common causes of retaining wall failure.
How thick should a concrete retaining wall be?
Wall thickness depends on height and the soil load behind it, but most residential concrete retaining walls under one metre use around 150–200mm of reinforced concrete. Taller walls need thicker sections, deeper footings, and engineered reinforcement with N12 bar. Always get a structural design for anything retaining significant soil height.
How much does a concrete driveway cost in Australia?
A standard concrete driveway costs $65–$150/m² depending on thickness, reinforcement, finish, and location. A double driveway of ~50m² typically costs $3,500–$7,500. Exposed aggregate and decorative finishes cost more than plain broom-finished concrete.
How thick should a concrete slab be for a driveway?
Residential driveways should be a minimum 100mm (4 inches) thick with SL72 or SL82 mesh reinforcement. For areas with heavy vehicles or truck access, 125–150mm with rebar reinforcement is recommended. Thicker slabs are needed for reactive soils.
How long does concrete take to cure?
Concrete reaches about 70% strength in 7 days and full strength at 28 days. Light foot traffic can resume after 24–48 hours. Vehicles should wait at least 7 days. In cold weather, curing slows significantly — your concretor may use curing compounds or covers.
What is exposed aggregate concrete?
Exposed aggregate concrete has the top layer of cement paste removed (by washing) to reveal the stones within the mix. It's popular for driveways, paths, and pool surrounds as it provides a decorative finish with natural slip resistance. It costs 15–25% more than plain concrete.
Why does concrete crack?
All concrete eventually cracks due to shrinkage, thermal movement, or ground movement. Control joints are deliberately placed every 3–4 metres to direct cracking. Cracks wider than 3mm or that are heaving or sinking indicate a structural issue requiring assessment.
