Fast, Free & Accurate Concrete Estimates for Wodonga, VIC
Calculate exactly how much concrete you need for any project in Wodonga — slabs, driveways, footings, columns, and steps. Get volume in m³, bag count, and 2026 cost estimates instantly.
Whether you're pouring a backyard slab, a driveway, or footings for a new structure in Wodonga, our free calculator gives you accurate concrete quantities and 2026 price estimates in seconds.
Over-ordering or under-ordering concrete wastes both money and time. Our Wodonga concrete calculator gives you a precise m³ figure so you can confidently order from local suppliers — no guesswork, no costly shortfalls on pour day.
From standard rectangular slabs and driveways to round post-hole footings and stepped areas, the calculator handles the most common residential and commercial concrete scenarios seen across Wodonga and the wider Border region.
Ready-mix concrete in Wodonga typically ranges from $180 – $260 per m³ in 2026, depending on mix strength, additives, and delivery distance. Use the cost estimator tab to get a ballpark figure before calling your supplier.

The calculator uses standard volumetric formulas to determine how much concrete your project requires. For rectangular pours the formula is straightforward; for round columns it uses the circular cross-section area. A wastage factor is then applied to ensure you don't run short on pour day in Wodonga's variable conditions.
Volume = L × W × T | Always measure in metres
Tip: Convert thickness from mm to metres before calculating (e.g. 100 mm = 0.10 m)
Wodonga sits on the Victorian side of the NSW–VIC border, served by regional concrete batching plants in both Wodonga and nearby Albury. Delivery costs are generally lower for projects within 15–20 km of the plant. The table below shows 2026 guide prices for common mix strengths.
| Mix Strength | Common Use | Price per m³ (AUD) | Min. Order | Slump |
|---|---|---|---|---|
| N20 (20 MPa) | Paths, garden edging, low-load slabs | $180 – $200 | 0.2 m³ | 80 mm |
| N25 (25 MPa) | House slabs, footpaths, shed floors | $200 – $225 | 0.2 m³ | 80–100 mm |
| N32 (32 MPa) | Driveways, garage floors, crossovers | $225 – $245 | 0.2 m³ | 100 mm |
| N40 (40 MPa) | Commercial slabs, structural elements | $245 – $265 | 0.5 m³ | 100–120 mm |
| Coloured / Exposed | Decorative driveways, patios | $260 – $320 | 1 m³ | 80 mm |
Different projects in Wodonga require different concrete thicknesses, mix strengths, and reinforcement. The guide below covers the most common residential applications across Wodonga, Baranduda, Wodonga East, and surrounding areas.
Standard residential slabs in Wodonga are typically 100 mm thick using an N25 mix, with mesh reinforcement (SL82 or SL92). For reactive soils — common in parts of the Upper Hume region — an engineer may specify a waffle pod or raft slab design. Always check your soil classification with a geotechnical report before ordering.
Driveways in Wodonga should be a minimum 100–125 mm thick using N32 mix for standard passenger vehicles, or 150 mm for heavier vehicles. Control joints every 3–4 m prevent cracking. A broom or exposed aggregate finish adds slip resistance — important during Wodonga's cold, sometimes frosty winters.
Strip footings for single-storey construction in Wodonga are typically 300 mm wide × 200 mm deep with N25 or N32 concrete and R10 tie bars. For two-storey or bushfire-prone areas, an engineer's specification supersedes any general guide. Always confirm footing depths with your building surveyor.
Residential paths and patios in Wodonga are typically poured at 75–100 mm thick using N20 or N25 concrete. A light broom finish or exposed aggregate surface provides grip. Adding a 10% wastage factor is standard practice for formed path work to account for ground irregularities.
Fence posts and pergola footings in Wodonga typically require 300–450 mm diameter holes at 600–900 mm depth, filled with N25 concrete. Our round column calculator handles this automatically — enter the hole diameter, depth, and number of posts to get the exact bag or cubic metre quantity needed.
Concrete steps in Wodonga use a standard rise of 150–175 mm and run of 250–300 mm to meet NCC (National Construction Code) requirements. Steps are typically formed with N32 concrete and finished with a broom texture or non-slip coating for safety. Our steps calculator uses the triangular volume method for accurate estimates.
| Project Type | Thickness (mm) | Mix Strength | Reinforcement | Wastage % |
|---|---|---|---|---|
| Footpath / Garden path | 75 – 100 | N20 | SL72 mesh (optional) | 5 – 10% |
| Patio / Alfresco | 100 | N25 | SL82 mesh | 10% |
| House slab | 100 | N25 – N32 | SL82 / SL92 | 10% |
| Garage floor | 100 – 125 | N32 | SL92 mesh | 10% |
| Driveway (light vehicles) | 100 – 125 | N32 | SL92 mesh | 10% |
| Driveway (heavy vehicles) | 150 – 175 | N40 | N12 bar | 10 – 15% |
| Strip footing | 200+ | N25 – N32 | R10 tie bars | 10% |
| Retaining wall | 150 – 200 | N32 | N12 bar @ 200 crs | 15% |

For very small jobs in Wodonga where ready-mix isn't practical, pre-mixed bags from hardware stores are an option. Use the table below to estimate how many bags you'll need.
| Bag Size | Yield per Bag (m³) | Bags per 1 m³ | Approx. Price per Bag (AUD) | Cost per m³ |
|---|---|---|---|---|
| 20 kg bag | 0.009 m³ | ~111 bags | $8 – $12 | ~$900 – $1,320 |
| 25 kg bag | 0.011 m³ | ~91 bags | $10 – $15 | ~$910 – $1,365 |
| 40 kg bag | 0.018 m³ | ~56 bags | $16 – $22 | ~$896 – $1,232 |
