Stone Selection
Pick your aggregate — size, colour, blend. We keep local and imported stone samples in the shop.
Pour & Retarder
Quality-mixed concrete poured and finished, with a surface retarder applied to pause the top 3–5mm from setting.
Wash & Expose
After the body has cured, we wash the retarded paste away to expose the stone — timing is everything.
Seal
Penetrating sealer locks in the finish without changing the feel underfoot.
Exposed Aggregate we've built.
Common questions
Is exposed aggregate slippery when wet?+
No — it is actually one of the most slip-resistant concrete finishes, which is why pool decks and sloped driveways use it.
How long does it take to install?+
A typical residential driveway takes 3–5 days from form-up to final wash, depending on size and weather.
