Exposed aggregate vs plain concrete: which is right for you?

Both plain concrete and exposed aggregate make excellent surfaces. Plain concrete costs less and gives a clean, simple look. Exposed aggregate costs more and delivers a textured, high-end finish with better grip. Your budget, how visible the area is, and how much slip resistance you need should guide the choice.

I’m David Bunce, owner-operator of Bunce Concrete and Construction. Over 18 years I’ve laid both finishes across thousands of square metres in Logan, Ipswich, Brisbane Southside and the Northern Gold Coast. Here’s how they compare in real Queensland conditions.

Plain concrete

Plain concrete – also called broom-finished concrete – is the standard finish most people picture when they think of concrete. The surface is smoothed and then lightly broomed to create a non-slip texture.

Advantages of plain concrete

• Most affordable option – plain concrete offers the lowest cost per square metre
• Clean, simple appearance – works well with any home style
• Low maintenance – occasional pressure washing keeps it looking fresh
• Quick installation – no additional finishing steps required
• Can be coloured – add pigment to the mix for a coloured concrete finish at a modest extra cost

Considerations

• Can look basic compared to decorative options
• Limited visual texture
• May show tyre marks more visibly on lighter colours

Exposed aggregate

Exposed aggregate is achieved by washing away the top layer of concrete before it fully cures, revealing the natural stone aggregate within. The result is a textured, multi-toned surface that looks and feels premium.

Advantages of exposed aggregate

• Visually striking – natural stone creates a unique, high-end appearance
• Excellent slip resistance – the textured surface provides great grip, even when wet
• Highly durable – the exposed stone surface resists wear and fading
• Low maintenance – periodic resealing (every 3–5 years) keeps it protected
• Adds property value – one of the most popular finishes for kerb appeal

Considerations

• Higher cost than plain concrete (the premium reflects the additional finishing work)
• Requires skilled application – the wash timing is critical
• Some aggregate types may be more expensive depending on supply

Appearance and kerb appeal

Appearance is where these 2 finishes differ most. Plain concrete gives you a flat, uniform surface. That suits modern homes and areas where you want the concrete to sit quietly in the background. Coloured plain concrete lifts the look without adding texture.

Exposed aggregate is the opposite. The washed surface shows off the natural stone, so no 2 slabs look identical. You can pick the aggregate to match your home – warm river pebbles, cool grey granites, or speckled blends. For a front driveway or entrance, that texture reads as a deliberate design choice. It’s the single biggest reason clients choose it for street-facing work.

Slip resistance and comfort underfoot

This is the part most people forget until they’re standing on the finished slab in the middle of a Queensland summer.

Both finishes grip well when they’re built correctly. A properly broomed plain slab is not slippery. But exposed aggregate has the edge in wet conditions. The raised stone breaks up surface water and gives bare feet and tyres something to hold. That matters around pools, on sloped driveways, and anywhere water pools after a storm.

Comfort underfoot is a genuine trade-off in our climate. Concrete absorbs heat, and a dark surface in full afternoon sun gets hot enough to sting bare feet. Two points worth knowing:

• Lighter colours stay cooler. A pale aggregate or a light plain mix reflects more heat than a charcoal finish.
• Texture spreads the heat. The uneven surface of exposed aggregate means less flat contact with your foot, so it often feels a touch cooler than a smooth dark slab at the same temperature.

If the area is a barefoot zone – a pool surround or a patio you’ll use all summer – lean towards lighter tones whichever finish you pick.

Durability and maintenance

Both finishes last decades when the base is prepared and the concrete is poured to the right thickness. Good ground preparation matters far more than the finish on top. That’s true for a driveway carrying vehicles and a pathway carrying foot traffic.

Day to day, plain concrete is the easier surface to clean. It’s smooth, so a pressure wash lifts dirt quickly. Exposed aggregate needs a little more care in the textured surface, and it benefits from resealing every 3 to 5 years to keep the stone bright and protected. That sealer also makes spills easier to wash off, which is handy around entertaining areas.

Neither finish is high-maintenance. The exposed aggregate reseal is a modest, occasional job – not an annual chore.

Cost: what you’re really paying for

Plain concrete is the lower-cost option per square metre. There are fewer finishing steps, so the labour is lighter. Exposed aggregate costs more because it takes an extra stage – the timed wash – and that stage has to be judged right. Wash too early and stone lifts out; too late and it won’t reveal. Getting that window correct is where experience earns its keep.

I won’t quote figures here because every job is different. Slab size, access, the aggregate you choose, and site conditions all move the price. The honest way to compare is a site visit and a written quote. What I can say is that the gap between the 2 finishes is usually smaller than people expect, especially once you factor in how long exposed aggregate holds its looks.

Which finish suits which project

Matching the finish to the job is where I spend most of my time advising clients.

• Driveways: Exposed aggregate is the popular pick for front driveways – it handles vehicle traffic, resists tyre marking, and lifts kerb appeal. On a steep driveway, its grip is a genuine safety benefit. Plain concrete is a sound, budget-friendly choice for a side or secondary driveway.
• Pathways: For a main front path, exposed aggregate ties the entrance together. For side paths and service access down the boundary, plain concrete does the job for less.
• Pool surrounds: Exposed aggregate is hard to beat here. Wet feet, splashed water and safety all point to a textured, slip-resistant surface. Choose a lighter aggregate so it stays comfortable underfoot in summer.
• Patios and entertaining areas: Either works. Coloured plain concrete gives a smooth, modern base for outdoor furniture. Exposed aggregate adds texture and hides the odd mark from a busy space.

Can you mix finishes?

Absolutely. Many of my clients use exposed aggregate for the driveway and plain concrete for the side pathways and shed slab. This keeps the overall cost reasonable while putting the premium finish where it matters most – the street-facing areas. Mixing finishes is one of the smartest ways to get a high-end look without paying the premium across every square metre.

Which should you choose?

Here’s my general advice after 18 years in the trade.

Choose plain concrete if:

• You’re working to a tighter budget
• The area is primarily functional – shed slabs, side pathways, secondary access
• You prefer a clean, minimal look
• Easy cleaning is a priority

Choose exposed aggregate if:

• The area is highly visible – front driveway, main pathway, entertaining area
• Slip resistance matters – pool surrounds, sloped driveways
• You want texture and a premium finish that lasts decades
• You’re happy to reseal every few years to keep it looking its best

There’s no wrong answer. The right finish is the one that fits your budget, your climate and how you’ll use the space.
