Aggregate Types
The aggregate that is mixed with the concrete can be pebbles of varying sizes, shells or even crushed stone, which gives a very fine finish, and as the aggregate is pre-mixed with the concrete, the risk of loose stones is eliminated. There are specialist concrete suppliers that offer exposed aggregate in Melbourne, and if you take a look at some driveways in that city, you will see just how much variation there is with the colour and the finish.
Colours
The supplier can create any shade that you like, and with the coloured oxide pre-mixed, you are sure of an even colour throughout the batch. If you choose a rich colour, it is recommended to have the driveway sealed, which offers a high level of protection, and with a professional installation, you are sure of a first-class outcome. If you would like to explore the colour options, search online for a local supplier and they can show you their colour catalogue, and can probably replicate any colour of your choosing.
Ground Preparation
It is generally recommended to have at least two inches of loose gravel laid prior to pouring the concrete, as this aids drainage, and depending on the type and density of the soil, the base should be compacted prior to pouring the concrete. Larger areas should also have steel reinforcement mesh laid prior to the ready mix being poured into the form, as this gives the concrete added tensile strength.
Sourcing a Supplier
While there would be several companies in the vicinity of your home that supply and install exposed aggregate driveways, you should select a contractor who can furnish you with some local references, which will allow you to see their workmanship for yourself. After making contact, the supplier would send a technician to your home, where you can both discuss the many finish options, and once a design has been chosen, they can quote for the project.
Installation
The project might take as long as 3 or 4days to complete, especially if the old driveway needs to be removed, and after a day or so, the ground would be ready for the mix to be poured. How much drainage added would depend on the drainage qualities of the ground, but in most cases, a layer of gravel is recommended. The finishing would be completed while the concrete is still wet, and once set, the timber forms would be removed, then edging stones fitted to complete the job.
If you decide on exposed aggregate for your driveway, you certainly wouldn’t be alone, as many Australian homeowners have opted for this stunning and hardwearing surface.
