Exposed Aggregate Driveways Gold Coast
Tired of plain grey concrete that looks cheap, stains easily, and becomes dangerously slippery when wet? Our QBCC-licensed team pours engineered exposed aggregate driveways, pool surrounds, and patio slabs using local Gold Coast pebbles, high-strength N32 concrete, and commercial UV sealers compliant with AS 3600 & AS 2870.

What is Exposed Aggregate Concrete & How Does It Work?
Exposed aggregate concrete is a premium decorative concreting technique where the top layer of cement matrix is washed away before curing, exposing natural stones, quartz pebbles, or crushed granite embedded beneath. Unlike plain broomed concrete, exposed aggregate provides superior structural grip and timeless architectural beauty.
Exposed Aggregate vs. Plain Concrete
Plain concrete is inexpensive but prone to visible tire marks, oil absorption, and a dull utilitarian look. Exposed aggregate hides dirt, provides exceptional wet-weather foot traction, and increases property resale value across Gold Coast residential estates.
Exposed Aggregate vs. Pavers
Paving stones shift over time, allowing weeds to sprout between joints. Exposed aggregate is a solid, continuous reinforced slab that eliminates weeds, ant mounds, and unlevel tripping hazards permanently.
Climate & Ground Factors Affecting Exposed Aggregate in SEQ
Concreting on the Gold Coast requires deep understanding of local environmental conditions:
- • Subtropical Humidity & Wash Timing: High humidity alters concrete set times. Our crews monitor surface hydration closely so the top cement paste is washed at the exact micro-window for uniform aggregate exposure.
- • Salt Air Exposure (Hope Island & Sanctuary Cove): Coastal salt spray can erode poor quality concrete. We pour high-density N32 grade concrete with marine-grade UV acrylic sealers to prevent salt pitting.
- • Reactive Clay Soils (Pimpama & Coomera): Expansion in clay soils causes plain slabs to crack. We install 50mm compacted roadbase and SL82 steel reinforcement mesh on bar chairs per AS 2870.
Our Exposed Aggregate Pouring Process
Excavation & Base Compaction
We excavate topsoil to 150mm depth, compact the subgrade using heavy mechanical plate compactors, and lay a solid 50mm roadbase sub-base to prevent slab movement.
SL82 Mesh & Formwork Setup
We set straight timber edge formwork, lay plastic moisture underlay, and elevate heavy SL82 steel reinforcement mesh on 50mm plastic bar chairs per AS 2870.
N32 Concrete Pour & Surface Retarder
We pour high-density N32 concrete premixed with natural QLD river pebbles, screed level, hand float, and apply a specialized chemical surface retarder to control curing.
Pressure Wash & UV Acrylic Sealing
At the exact hydration window, we high-pressure wash away top cement paste to reveal the aggregate, saw-cut control joints, and seal with 2 coats of UV solvent acrylic sealer.
Why Cheap Exposed Aggregate Jobs Fail (And How We Fix It)
We are frequently called to repair or replace botched exposed aggregate driveways poured by unlicensed operators. Here are the 3 most common failure modes:
1. Patchy Aggregate Exposure
Washing off the top paste too early dislodges pebbles creating deep hollows; washing off too late leaves ugly cement film over the stones. Our crew uses precision retarder spray and timed wash-off for 100% consistent stone exposure.
2. Steel Mesh Sinking to Bottom
Unlicensed concreters lay steel mesh directly on the dirt instead of elevating it on plastic bar chairs. The steel rusts from ground moisture and the slab snaps under vehicle weight. We elevate all SL82 mesh on 50mm chairs.
3. Skipping UV Solvent Sealer
Failing to apply 2 coats of UV-stable solvent acrylic sealer allows engine oil stains and green algae to soak into porous pebbles. We apply commercial-grade clear acrylic sealers to lock in color and shine.
Exposed Aggregate Service Suburbs
Exposed aggregate is our most requested finish across Northern Gold Coast communities:

What Property Owners Say
"Had an exposed aggregate driveway poured for our canal home in Hope Island. Non-slip finish around our pool path and the pebble blend matches our landscaping perfectly!"
Sarah M.
Homeowner, Hope Island"Poured a 110m² exposed aggregate driveway in Ormeau Ridge. Solid N32 mix, SL82 steel mesh on chairs, and high quality UV sealer. Highly recommend!"

Frequently Asked Questions — Exposed Aggregate
Q: How much does an exposed aggregate driveway cost on the Gold Coast?
A: Exposed aggregate costs depend on driveway size, chosen pebble aggregate blend, excavation depth, site access, and sealer grade. Because every site is unique, we do not provide fixed online estimates. Call us on 0411 914 157 or fill out our quick quote form for a free, accurate, no-obligation on-site quote.
Q: Is exposed aggregate concrete slippery around swimming pools?
A: No. Unlike smooth troweled concrete, exposed aggregate features natural stone textures that provide superior slip resistance, making it ideal for Gold Coast pool surrounds and wet entertaining areas.
Q: How do you prevent exposed aggregate driveways from cracking?
A: We prevent cracking by compacting a 50mm roadbase sub-base, placing SL82 steel mesh on bar chairs, pouring N32 concrete, and saw-cutting expansion control joints every 3 to 4 metres.
Q: How long before I can drive on a new exposed aggregate driveway?
A: Foot traffic is permitted after 24 to 48 hours. We recommend keeping passenger vehicles off the slab for 7 days, and heavy caravans or trucks off for 28 days.
Q: How often should an exposed aggregate driveway be re-sealed?
A: We recommend re-sealing exposed aggregate driveways every 2 to 3 years with commercial UV solvent acrylic sealer to preserve stone color vibrancy and prevent oil absorption.
