Determining the cost of a concrete slab can be a complex process, with several factors affecting the final price. Whether you’re planning a driveway, patio, or foundation, having a clear understanding of potential expenses is crucial for budgeting effectively. To make things easier, a concrete slab cost calculator can simplify the process by giving you a quick estimate.

This blog explores the cost differences between various types of concrete, highlights key factors that influence pricing, and shares practical tips for accurate estimates. With insights from trusted concreters, you’ll be better equipped to plan your next concreting project confidently.

The following are the cost per concrete type:

Plain concrete is the simplest option, offering a smooth grey finish that suits driveways, paths, and general slabs. Its affordability makes it a go-to choice, with costs ranging from $75 to $95 per square metre.

Exposed aggregate cost around $120 to $150 per square metre. It features a decorative, textured surface by revealing embedded stones or pebbles, and is perfect for driveways, patios, or outdoor areas.

Coloured concrete adds visual appeal through pigments mixed directly into the concrete. Commonly seen in decorative projects, it costs around $90 to $110 per square metre, offering a vibrant alternative to traditional finishes.

Stencilled concrete creates intricate designs, often mimicking bricks or tiles, with vibrant colours and detailed patterns. Suitable for driveways and patios, its price usually falls between $120 and $150 per square metre.

The factors influencing concrete slab costs are size and thickness, type of concrete mix, reinforcements, and finishing options.

The overall size and thickness of a slab significantly affect costs, with larger or thicker slabs requiring more materials and labour. These factors directly influence the concrete driveway cost for residential and commercial projects.

Different mixes, including standard, reinforced, or decorative options, impact pricing. High-strength or specialised mixes designed for specific conditions often increase costs compared to basic concrete used in standard applications.

Adding reinforcements like steel mesh or incorporating additives for durability or weather resistance raises expenses. These enhancements ensure stronger slabs capable of handling heavier loads or harsher conditions.

Finishes such as polishing, stencilling, or exposed aggregate provide decorative appeal but add to overall costs. These features transform basic slabs into visually appealing surfaces suited to unique design preferences.

Here are some tips to estimate concrete slab costs accurately:

Start by outlining your project details, including dimensions, site conditions, and required materials. Pinpointing these specifics helps you estimate costs more accurately and reduces the chance of surprises during construction.

Reach out to experienced concreters to get reliable advice on materials, labour, and finishes. Their expertise ensures you stay on track with pricing and avoid costly mistakes in your project planning.

Always leave room in your budget for unexpected expenses, like extra materials or weather-related delays. Preparing for these possibilities keeps your project moving smoothly without financial setbacks.
