Driveways are a key part of any residential or commercial property in Melbourne. They support daily vehicle movement, improve street appeal, and add long-term value. When planning new concrete driveways Melbourne, property owners often compare two popular options: exposed aggregate concrete and plain concrete.
Both materials are strong and suitable for Melbourne’s weather conditions, but they differ in cost, appearance, durability, and maintenance needs. This guide explains the technical differences between exposed aggregate concrete Melbourne and plain concrete, with a clear focus on price and long-term performance.
Understanding Plain Concrete Driveways
Plain concrete, also known as standard grey concrete, is the most traditional driveway material used across Melbourne suburbs. It consists of cement, sand, coarse aggregates, and water. Once poured and levelled, the surface is finished with tools to create a smooth or lightly textured layer.
Key Characteristics of Plain Concrete
Plain concrete is widely used because it is:
- Cost-effective
- Easy to install
- Structurally strong
- Suitable for residential and light commercial use
Most civil construction company Melbourne projects use plain concrete where budget and functionality are the main concerns. It can also be enhanced with different concrete driveway finishes Melbourne, such as broom finish or trowel finish, to improve surface grip.
Performance in Melbourne Conditions
Melbourne experiences varied weather, including hot summers, heavy rain, and occasional cold spells. Plain concrete performs well in these conditions if it is properly reinforced and cured. However, its smooth surface can sometimes become slippery when wet unless a textured finish is applied.
Understanding Exposed Aggregate Concrete Driveways
Exposed aggregate concrete is a decorative finish in which the upper layer of cement paste is removed to expose the natural stones embedded within the surface. The aggregates can include crushed stone, quartz, granite, or river pebbles.
This finish has become increasingly popular for exposed aggregate driveways Melbourne due to its premium appearance and strong surface properties.
How Exposed Aggregate Is Constructed
The process includes:
- Pouring the concrete mix.
- Applying a surface retarder.
- Washing off the top cement layer.
- Exposing the embedded stones.
The result is a textured, non-slip surface with a natural stone look. Many homeowners choose aggregate concrete Melbourne for modern homes because it matches landscaping and architectural designs.
Price Comparison: Exposed Aggregate vs Plain Concrete in Melbourne
Cost is often the first factor considered when choosing between these two driveway options. The total price depends on site conditions, thickness, reinforcement, drainage requirements, and access.
Plain Concrete Cost in Melbourne
On average, plain concrete driveways in Melbourne cost between:
- $65 to $100 per square metre
The lower price range applies to standard residential installations with simple layouts. Additional costs may include excavation, base preparation, reinforcement mesh, and edging.
Because of its lower material cost and simpler finishing process, plain concrete remains the budget-friendly option for concrete driveways Melbourne.
Exposed Aggregate Concrete Cost in Melbourne
Exposed aggregate driveways generally cost:
- $100 to $150 per square metre
The price is higher because:
- Premium decorative aggregates are used.
- The finishing process requires more labour.
- Surface treatment materials are needed.
- Skilled workmanship is essential.
A professional civil contractor Melbourne will also ensure proper curing and sealing, which adds to the total project cost but improves durability.
Why the Price Difference Exists
The main reasons exposed aggregate costs more include:
- Decorative stone selection
- Additional labour for washing and finishing
- Higher surface preparation standards
- Sealing requirements
While the upfront cost is higher, many property owners see exposed aggregate as a long-term investment due to its durability and appearance.
Durability Comparison
Durability is critical for driveways that handle daily vehicle loads. Both materials are strong, but their surface performance differs.
Structural Strength
Both plain concrete and exposed aggregate use similar base concrete strength ratings, typically 25 MPa to 32 MPa for residential driveways. When installed by a qualified civil construction company Melbourne, both systems can support cars, SUVs, and light commercial vehicles.
Reinforcement mesh and proper sub-base compaction are more important than the surface finish when it comes to structural durability.
Surface Wear and Abrasion Resistance
Exposed aggregate has an advantage in terms of surface wear resistance. The embedded stones are harder than cement paste. This means:
- Less visible surface wear
- Reduced tyre marking
- Better resistance to abrasion
Plain concrete surfaces may show tyre marks, minor cracks, or surface scaling over time, especially if not sealed properly.
Slip Resistance
Slip resistance is an important factor in Melbourne’s rainy conditions.
Exposed aggregate provides:
- Natural texture
- Improved grip
- Safer walking surface
Plain concrete may require a broom finish to improve traction. Without texture, it can become slippery when wet.
Crack Resistance
Cracking depends on:
- Proper joint placement
- Sub-base preparation
- Reinforcement
- Correct curing
Both materials can crack if installation standards are not followed. An experienced civil contractor Melbourne will design control joints to reduce visible cracking.
Exposed aggregate can hide minor hairline cracks better than plain concrete because of its textured appearance.
Maintenance Requirements
Maintenance affects long-term costs and visual appeal.
Plain Concrete Maintenance
Plain concrete requires:
- Occasional cleaning
- Sealing every 2 to 3 years
- Crack repair if needed
Oil stains and dirt are more visible on grey surfaces. Regular pressure washing helps maintain appearance.
Exposed Aggregate Maintenance
Exposed aggregate requires:
- Cleaning to remove dirt between stones
- Sealing every 2 to 3 years
- Moss and algae removal in shaded areas
Although sealing is necessary, exposed aggregate hides stains better due to its mixed colour texture.
In both cases, working with a professional civil construction company Melbourne ensures proper sealing and surface protection.
Aesthetic Comparison
Appearance plays a major role in driveway selection.
Plain Concrete Look
Plain concrete offers:
- Clean, simple grey finish
- Modern industrial appearance
- Compatibility with most home designs
It can also be coloured or combined with different concrete driveway finishes Melbourne to improve visual appeal.
Exposed Aggregate Look
Exposed aggregate offers:
- Decorative stone texture
- Custom colour combinations
- Premium architectural appearance
Many high-end residential properties in Melbourne prefer exposed aggregate driveways Melbourne because they improve street appeal and property value.
Installation Process Comparison
The overall construction timeline for both driveway systems is broadly similar because excavation, subgrade preparation, and structural concrete placement follow the same engineering standards. However, exposed aggregate involves additional surface treatment stages that demand more skilled labour and close timing control, which slightly increases project duration and cost compared to plain concrete.
Plain Concrete Installation
Plain concrete installation follows a straightforward structural process designed for durability and load performance. The typical steps include:
- Excavation to required depth
- Compaction and base preparation
- Formwork installation
- Concrete pouring
- Surface finishing (broom, smooth, or trowel finish)
- Proper curing to achieve design strength
Once curing is completed, the driveway can be used after the recommended strength gain period.
Exposed Aggregate Installation
Exposed aggregate follows the same structural foundation process but adds decorative finishing stages. The steps include:
- Same excavation and base preparation
- Placement of decorative aggregate concrete mix
- Application of surface retarder to delay top-layer cement setting
- Controlled pressure washing to expose natural stones
- Sealing after full curing for protection and colour enhancement
The additional washing and sealing stages require precision timing and experienced workmanship, which increases labour intensity and overall installation cost compared to plain concrete.
Long-Term Value in Melbourne
When comparing long-term value, both systems perform well if correctly installed.
Plain concrete provides:
- Lower initial cost
- Strong structural performance
- Suitable for budget-focused projects
Exposed aggregate provides:
- Higher visual appeal
- Better slip resistance
- Improved surface durability
- Strong resale value impact
For property developers and homeowners aiming for premium finish, aggregate concrete Melbourne often offers better long-term aesthetic value.
