Concreting Driveway vs Exposed Aggregate Costs: What Does the Finish Really Add?

Plain concrete and exposed aggregate often sit in the same conversation, but they are not the same budget category. Both need base preparation, reinforcement and finishing, yet exposed aggregate adds process, material selection and finishing risk that push the quote up. The right choice comes down to whether that visual upgrade is worth the extra money on your site.

Typical Cost Comparison

Driveway finish	Low	Average	High
Plain concrete driveway	$70/m²	$100/m²	$140/m²
Exposed aggregate driveway	$100/m²	$140/m²	$220+/m²

Exposed aggregate requires decorative stone in the mix, more careful finishing, washing back at the right time, and a higher presentation standard. It is less forgiving than plain concrete. If the contractor gets the timing wrong, the finish suffers. That risk is priced in. Both finishes still need excavation, compacted base preparation, formwork, reinforcement, control joints and drainage fall.

Plain concrete is better value when the driveway is long, purely functional, or likely to take heavy use with little concern for architectural presentation. Exposed aggregate earns its keep when street presentation matters, the home already has premium landscaping, or the driveway is a major visual surface from the front boundary.

Buying Tips

1. Ask for the base-prep scope in writing.
2. Check whether sealing is included and when it happens.
3. Ask to see local finished jobs that are at least a year old.
4. Confirm the exact aggregate mix and border detail.
5. Do not compare decorative concrete quotes with vague plain-concrete allowances.

Frequently Asked Questions

How much more is exposed aggregate than plain concrete?

Often 25–50% more, though the gap can widen further on premium stone mixes and detailed borders.

Does exposed aggregate last longer?

Not necessarily. Longevity depends more on base preparation, thickness, drainage and workmanship than on the decorative finish.

Is plain concrete easier to repair?

Usually yes. Matching exposed aggregate repairs can be more difficult because stone colour and exposure depth vary.

Which adds more street appeal?

Exposed aggregate usually does, especially on contemporary homes and landscaped frontages.

How We Collect These Prices

WhatCosts compares concreting prices by finish, access and preparation scope so owners can see the real uplift between functional slabs and decorative driveway work. We also look at adjacent site work like drainage, paving edges and excavation because driveway value is shaped as much by prep as by finish.
