Exposed aggregate concrete has become a popular choice for driveways, patios, and pavement areas. This concrete has a warm, stone-like appearance and can be coloured with oxides to create a range of unique and appealing designs. It is particularly suitable for areas that are exposed to high traffic and is resistant to tyre marks.
Exposed Aggregate Concrete – Decorative Pebble Finish
Exposed aggregate concrete is more expensive to pour than other types of concrete. It should be poured using concrete forms (made from 2x4s or 2x6s), leveled with gravel or dirt, and smoothed with a bull float or 2×4. You should also apply a surface retarder to protect the exposed aggregates before pouring. Once the concrete has set, remove the forms.
Exposed aggregate concrete is an attractive exterior concrete surface, but it requires a skilled crew and precise technique. An untrained crew may not be able to install it properly, resulting in a poor finish. As with any type of concrete, the best way to avoid a substandard result is to hire a professional.
Exposed aggregate is especially good for patios and pathways, where it is non-slip and not susceptible to cracking. It is also a cost-effective option for wet and slippery areas.
