Thinking of upgrading your driveway or patio but confused about which concrete finish to choose? The finish you choose changes more than just appearance. It also affects safety, cleaning, cost and how easy it is to refresh later. Whether you’re starting fresh or replacing old concrete, choosing the right style can help you enjoy your space for years to come. In this guide, we’ll explain the key differences between two popular choices in plain concrete and exposed aggregate. You’ll see how they compare in style, price, strength, maintenance and which one might suit your home best.
What is plain concrete?
Plain concrete is the regular grey concrete you see in many homes and businesses. It often has a light texture added to it so it’s not slippery. Many people choose it because it’s affordable and strong. Standard concrete is as hard as stone, and can withstand heavy weight and pressure. It is made by mixing cement, gravel, sand, and water. Some mixes also include small stones or special additives to improve strength.
What is plain aggregate?
Exposed aggregate is a decorative type of concrete in which stones, pebbles, or other materials are mixed and exposed on the surface. This gives it a more detailed and stylish look. It is just as strong and long-lasting as plain concrete, and provides better grip, especially when wet. Because it requires more steps to install properly, it is best done by experienced professionals like OZ Concreting Group.
Key Differences Between the Two
1. Appearance
The biggest difference is how they look. Plain concrete has a smooth and even surface. The stones inside are fully covered, giving it that simple, classic grey finish most people know.
Exposed aggregate shows the stones on top. You can actually see pebbles, rocks, or other materials in the surface. This creates a textured, colourful finish that adds more personality and style to outdoor areas.
2. Installation Process
The way they are installed is also different.
Plain concrete installation is simple
- Mix cement, water, and aggregates
- Pour into the prepared area
- Level and smooth it
- Let it cure
- And it’s done!
Exposed aggregate needs extra steps:
- Mix cement, water, and chosen decorative stones
- Pour into the prepared area
- Level and smooth it
- Wait until it starts to harden
- Wash or brush off the top layer to reveal the stones
3. Texture and Grip
Safety matters, especially near pools or in rainy areas.
Plain concrete feels smoother and can become slippery when wet.
Exposed aggregate has a rough surface because of the stones. This gives better grip and makes it safer for driveways, pool areas, and wet spaces.
4. Customisation Options
Plain concrete has limited design choices. You can add colour, but the surface still looks mostly the same.
Exposed aggregate gives many design options:
- Choose from river stones, crushed granite, quartz, or recycled glass
- Mix different colours for a unique look
- Combine with coloured concrete
That’s why many homeowners choose exposed aggregate for a more premium outdoor finish.
5. Maintenance Needs
Both options are easier to care for than timber decks or pavers, but they differ slightly.
Plain concrete usually needs:
- Occasional cleaning
- Crack repairs when needed
- Resealing every few years
Exposed aggregate needs:
- Regular cleaning (sometimes more often because of its texture)
- Crack repairs when needed
- Resealing every 2 to 3 years to keep it looking fresh
Even though exposed aggregate needs a bit more care, many people feel the stylish look is worth it.
6. Durability and Lifespan
Both types are strong and long-lasting. Exposed aggregate can handle wear slightly better because the stones are visible and protect the surface. Small marks or cracks are less noticeable due to the textured finish.
7. Cost Considerations
There is usually a price difference.
Plain concrete is more budget-friendly, which makes it ideal for large areas.
Exposed aggregate costs more because:
- Decorative stones can be more expensive
- Installation takes more labour
- Extra materials like sealers are needed
- Skilled workmanship is required
- Many homeowners believe the improved look makes the extra cost worthwhile, especially in visible areas like entrances or around pools.
Advantages of Plain Concrete

Advantages of Exposed Aggregate
Exposed aggregate offers both beauty and strength.
Aesthetic Appeal
The surface showcases natural stones, creating a textured and attractive look that adds depth and style.
Slip Resistance
Its rough finish improves grip, making it safe for walkways and wet areas.
Customization Options
With many stone types and color choices available, you can create a design that perfectly matches your home.
Which driveway option should you choose?
Ultimately, the choice between open aggregate concrete and plain concrete comes down to what’s most important to you. If you like a stylish look, good grip, and a surface that stands out, and you don’t mind paying a little extra up front, open aggregate is a great choice. If you want something simpler, cleaner, and more budget-friendly, plain concrete is still a strong and reliable option. Whatever you choose, hiring a skilled contractor like OZ Concreting Group and sealing the surface regularly will help your driveway last longer and protect your money.
Conclusion
Both plain concrete and exposed aggregate are great options for driveways, but they offer different advantages in style, cost, and maintenance. If you want something simple and budget-friendly, plain concrete is a smart choice. If you prefer a driveway that stands out and improves your home’s street appeal, exposed aggregate is a good option.

FAQs
Q1. How do you lay open aggregate concrete at home?
First, prepare the area properly. Then mix and pour the concrete and level it. You can mix the stones into the mix or spread them on top. Add a surface retarder, and once the concrete begins to harden, gently wash the top layer to reveal the stones underneath. Then, seal the surface to keep it strong and attractive.
Q2. What is the concrete around a swimming pool called?
