Exposed Aggregate Concrete is a very popular residential concrete application on the Gold Coast. With many different options for stone colours, there is always a choice that suits your natural surroundings of your house. However, Exposed Aggregate Concrete doesn’t always have to be just a standard plain grey concrete with different coloured aggregates. It can be mixed up in a few different ways to really create something unique for your property.
Installation of exposed aggregate is usually quite a simple process for a contractor with enough experience in it’s application. Exposed is all about timing by your contractor, it takes skill and experience to know the timings of each stage of it’s placement. Typically after placing and screeding off your Exposed Concrete, it is then floated and the surface is continually worked to bed and flatten the stone correctly. When the timing is right, the surface is then retarded by with Raw Sugar or a chemical compound specific to this requirement, then again, when the timing is correct, the surface will be washed off revealing the coloured stones underneath.
Variation 1: Inserts / Borders
One way of mixing things up is with inserts and borders. As you can see in the image installation of plain coloured concrete with exposed aggregate has been installed for the middle section, followed by the same aggregate being installed surrounding it with a simple colour through the concrete to change it up. You can also do this with borders, plain concrete with a colour and also inserting tiles and pavers directly into the concrete.
Variation 2: Colour Through Concrete
One of the simplest ways to change things up is to add a colour oxide through your concrete during the mixing stage. The Oxide mixes through the entire concrete body and once we wash off the surface, with the right choice in colour, contrasts against the stone choice of our clients. There area many different options for colouring your concrete, please check out our Colour Charts under Customer Relations to have a look.
Variation 3: Polishing to Expose
Our final way of finishing your Exposed Aggregate Concrete is to place the concrete as per normal, but instead of washing off the surface during placement, we will wait for the concrete to set and cure, then return with our grinding and polishing equipment to remove the surface revealing the stones, along with flattening the stones along the surface for a very sleek, modern finish. At times this finish can be slippery when wet, however we can add texture to the surface within the sealer to assist with this.
