Exposed Aggregate Driveways: Pros, Cons & Costs

If you’re looking for a driveway that stands out from standard concrete without going full interlock, exposed aggregate concrete is one of the most popular premium options available.

Homeowners often choose exposed aggregate for its decorative appearance, durability, and slip resistance — but it’s not the right choice for every property or budget.

In this guide, we’ll break down:

• What exposed aggregate actually is

• The real pros and cons

• How it compares to standard concrete

• What you can expect to pay

So you can decide if it’s the right fit for your home.

What Is an Exposed Aggregate Driveway?

Exposed aggregate is a decorative concrete finish created by removing the top layer of cement paste after the concrete is poured, revealing the natural stone underneath.

These stones can include:

• Pea gravel

• Crushed stone

• River rock

• Coloured or specialty aggregates

Once exposed, the surface is washed and sealed, leaving a textured, visually appealing finish that’s far more decorative than broom-finished concrete.

Pros of Exposed Aggregate Driveways

1. High-End Appearance

Exposed aggregate instantly upgrades curb appeal. The natural stone texture adds depth and character that plain concrete simply can’t match.

It pairs especially well with:

• Stone or brick homes

• Modern or craftsman-style architecture

• Landscaped front yards

No two exposed aggregate driveways look exactly the same.

2. Excellent Durability

When installed correctly, exposed aggregate concrete can last 25–30 years or more, similar to standard concrete.

The embedded stones help:

• Reduce surface wear

• Improve resistance to scaling

• Hold up well under vehicle traffic

This makes it a solid long-term investment.

3. Slip Resistance

The textured surface provides better traction than smooth concrete, especially when wet.

This is a big advantage for:

• Sloped driveways

• Walkways and stairs

• Homes with frequent foot traffic

In winter conditions, exposed aggregate generally offers better grip than smooth finishes.

4. Low Maintenance Compared to Interlock

Unlike interlock pavers, exposed aggregate:

• Has no joints to weed

• Won’t shift or settle individually

• Doesn’t require re-leveling

Routine maintenance typically involves:

• Occasional washing

• Resealing every 3–5 years

Cons of Exposed Aggregate Driveways

1. Higher Upfront Cost

Exposed aggregate costs more than standard broom-finished concrete due to:

• Specialized finishing techniques

• Higher labour requirements

• Decorative materials

For homeowners on a tight budget, this can be a deciding factor.

2. Surface Can Be Rougher

While great for traction, exposed aggregate is not as smooth as regular concrete.

This may be a drawback for:

• Basketball play

• Snow shoveling (stones can catch the blade)

• Barefoot walking

The size and type of aggregate used can help control how aggressive the texture feels.

3. Repairs Are More Noticeable

If exposed aggregate cracks or needs patching, repairs can be harder to blend seamlessly compared to plain concrete.

That’s why:

• Proper base preparation is critical

• Control joints must be placed correctly

• Experienced installation matters more with decorative concrete

How Exposed Aggregate Compares to Other Driveway Options

Exposed Aggregate vs Standard Concrete

• Cost: Higher

• Appearance: Much more decorative

• Maintenance: Similar

• Durability: Comparable

Exposed Aggregate vs Interlock

• Cost: Often similar or slightly lower

• Maintenance: Much lower

• Longevity: Comparable

• Repair flexibility: Interlock is easier to spot-repair

Each option has its place depending on priorities and budget.

Installation Timeline

An exposed aggregate driveway typically follows the same timeline as a standard concrete driveway:

• Removal & base prep: 1–2 days

• Forming & reinforcement: 1 day

• Concrete pour & exposure: 1 day

• Initial curing: 24–48 hours

• Vehicle access: 5–7 days

The exposure process requires precise timing, which is why experienced crews are essential.

Overall Price Estimates (Southern Ontario)

Costs vary depending on size, access, aggregate choice, and site conditions, but typical ranges are:

• Exposed aggregate driveway:
  $18,000 – $25,000+

For comparison:

• Standard concrete driveway: $10,000 – $15,000

• Decorative borders or accents: +$2,000 – $5,000

Factors that influence pricing include:

• Driveway size and thickness

• Type and colour of aggregate

• Base conditions

• Accessibility for equipment

A proper on-site assessment is the only way to get an accurate quote.

Is Exposed Aggregate Worth It?

Exposed aggregate is a great option if you:

• Want a premium, decorative finish

• Plan to stay in your home long-term

• Value durability and low maintenance

• Want something more unique than plain concrete

It may not be ideal if:

• Budget is the top priority

• You prefer a smooth surface

• You want the easiest surface to shovel in winter

Final Thoughts

Exposed aggregate driveways offer a balance between beauty and strength, making them one of the most popular decorative concrete options for homeowners who want more than the basics.

As with any concrete project, installation quality matters more than the material itself. Proper base preparation, timing, and finishing make the difference between a driveway that lasts decades and one that develops issues early.

If you’re considering exposed aggregate for your driveway, working with an experienced local contractor ensures the final result looks as good as it performs.
