StoneSet vs Exposed Aggregate: Which Surface Is Right for Your Project?

When planning a driveway, pathway, or outdoor space, two finishes often come up early in the conversation: StoneSet resin-bound paving and exposed aggregate concrete. Both use natural stone, both can look fantastic, and both have their place in residential and commercial projects.

Rather than telling you which is “better”, this guide simply lays out the facts — strengths, limitations, and ideal uses — so you can decide what’s right for your project.

 

1. Aesthetics & Design Flexibility

StoneSet

StoneSet offers extensive design flexibility because the stone is hand-trowelled into place rather than mixed in a concrete truck.

This means:

• Seamless areas with clever, more attractive control joint solutions
• Ability to follow curves, tree surrounds, pool edges & detailed landscaping
• Wide choice of Australian stone, Spanish marble & recycled materials
• Consistent ‘same every time’ colour even across large installations, being as simple as natural stone combined with crystal clear resin. No need for exposing and/or possible installation errors during such processes.

Exposed Aggregate

Exposed aggregate is limited to the stones available in the concrete mix. Larger areas often require multiple pours, which can result in:

• Noticeable, traditional control joins
• Slight colour inconsistencies
• A more traditional look that suits some homes but not all

If creative control and seamless finishes matter, StoneSet typically offers more freedom.

 

2. Permeability & Drainage

StoneSet

StoneSet can be installed as a fully permeable system, allowing stormwater to pass through at extremely high rates.

This supports WSUD principles, reduces runoff, and helps prevent pooling.

When used as a resurfacing layer, StoneSet’s permeability allows moisture below the slab to escape — minimising the risk of delamination or bubbling that occurs with traditional coatings.

Exposed Aggregate

Exposed aggregate concrete is not permeable.
Water remains on the surface and relies on falls, drains and control joints.

For sites with drainage or runoff challenges, StoneSet generally performs better.

 

3. Durability & Lifespan

StoneSet

StoneSet’s resin-bound system is flexible enough to absorb minor substrate movement. It doesn’t crack quite like concrete is guaranteed to, and carries:

• 10-year guarantee
• Design life 25+ years with normal maintenance

Exposed Aggregate

Concrete is a rigid material, so over time it will crack, especially on reactive soils, slopes, or where heavy vehicle loads occur.

Repairs are often visible because fresh concrete rarely matches the existing colour or texture.

If long-term aesthetics and reduced cracking are priorities, StoneSet has the advantage.

 

4. Safety & Slip Resistance

Both systems can achieve compliant slip ratings.

StoneSet commonly achieves P4–P5, remaining comfortable underfoot even when wet.
Exposed aggregate can also be slip-resistant but may become harsher or smoother over time depending on wear.

Both can be safe — StoneSet simply offers greater long-term consistency.

 

5. Cost Considerations

This is where the comparison becomes more project-specific.

When building from scratch (new slab):

• Exposed aggregate is generally cheaper upfront.
  Concrete, reinforcement, labour and aggregate can be cost-effective for large new areas.
• StoneSet over a new permeable base can be more expensive initially, but offers benefits like drainage and design flexibility.

When resurfacing existing concrete or asphalt:

• StoneSet is often the more cost-effective option.
  There’s no demolition, no disposal, and no need to pour a new slab.
  You reuse the existing surface as the base and upgrade the finish dramatically.

Exposed aggregate resurfacing isn’t practical — it requires ripping out and repouring.

If you already have a slab, StoneSet almost always becomes the smarter economic choice. For brand new applications, even where permeability isn’t required, StoneSet can be and often is installed over concrete for a more stone full, performance rich result.

 

6. Maintenance & Repairs

StoneSet

Maintenance typically involves pressure washing and optional rejuvenation coats every few years in high-use zones.

Localised repairs can blend well due to the hand-laid method.

Exposed Aggregate

Concrete repairs are much more visible.
Cracks rarely disappear, colour matching is difficult, and patching is noticeable.

For those wanting a surface that keeps looking good long-term, StoneSet is easier to maintain.

 

So… Which Is Better?

Both surfaces have their place, & as a consumer – that’s up to you to decide!
