Are the pebbles in exposed aggregate only in the top layer of the mix?

No, the aggregates chosen in each particular concrete mix are responsible for the colors and textures which result in the final product. This means that, unlike the traditional blue/grey screenings used in “normal” grey concrete, a wide variety of options are now available. These aggregates (or stones, screenings or pebbles as you may refer to them) are throughout the entire batch of concrete.

Once laid and trowelled, the concrete sprays a chemical on the surface of the concrete which slows down the “going off”, or setting, of the top few millimetres of the mix. Allowing several hours for the chemical process to take place, the concreter then pressure washes back the surface of the newly laid concrete to “expose” the aggregate in the mix. This is how the natural beauty of the various aggregates is revealed in an exposed aggregate design mix. Once sealed, the colors and textures are further enhanced.

How will I know the sample I choose will match my exterior designs at home?

All customers are welcome and encouraged to bring along a spare tile or brick from existing landscaping to choose a mix which best enhances and compliments the home.

For concreters, builders and landscapers, the on-site displays at Cranbourne Pre-Mix can streamline the selection and quoting process by refering your customer to directly view and choose a mix on site here. Looking forward to seeing you!

Can anyone lay exposed aggregate concrete?

Laying exposed aggregate concrete is a highly skilled technique. Concrete is laid, trowelled and then a retardant chemical applied prior to washing back and exposing the aggregate. So much knowledge and skill goes into a beautifully finished end product that we recommend you choose a concreter who has this experience. We are more than happy to put you in touch with a concreter that we have found to be experienced and professional in the laying of exposed aggregate concrete. Please feel free to contact Angelo or one of his team to refer you to a concreter who can then provide you with a quote.

How do I know how much concrete to order?
Concrete is ordered in cubic metres. If a concreter is doing your job, he will be able to measure up and estimate an accurate quantity of concrete to be ordered. If working on a small job at home, we can help you out with quantities required if provided with accurate metric measurements.
Is my concrete going to look exactly like the samples displayed?

Whilst we endeavour to maintain consistency in our exposed aggregate mix designs, we cannot guarantee that your job will be the same as previous deliveries or samples provided. Concrete is comprised of many different mined resources which vary naturally in colour, size and composition. Our samples on display, in our brochure, and online are provided as an indication only of the finished product and it is only natural that some variations may occur. Supply of some pebbles and aggregates is also difficult at times and it is always best to ensure your mix is currently available. When viewing samples on this website or in our brochure, keep in mind that colours vary in print and from browser to browser.. A better appreciation of the finished product can be found in viewing our many in-ground displays at 219 South Gippsland Highway, Cranbourne or by viewing your concreter’s previous job sites.

NB: All aggregates are a naturally mined resource and may vary in composition. Natural oxidation of minerals in aggregates can sometimes result in concrete rust stains for which Cranbourne Pre-Mix cannot be held responsible.
