While polished concrete remains a firm favourite, you will notice that exposed aggregate concrete driveways in Melbourne are on the rise. A decorative concrete driveway adds a stylish touch to any house, but there are a few ways you can achieve the exposed aggregate look.
Exposed aggregate concrete adds an extra dimension of aesthetic appeal to concrete, whilst harnessing the power of the concrete itself. It’s relatively cheap, easily moulded, strong and reliable. There are 2 basic ways to make an exposed aggregate.
Surface dressing achieves the exposed aggregate effect by pressing the aggregate into the freshly poured concrete. It’s a great way to achieve the decorative concrete look at lower cost. It’s also not the most skilled type of concrete driveway available in Melbourne, and even a good DIYer might be able to handle the job- if they’re confident with the laying of the concrete for the driveway. It isn’t the hardest wearing of the options, however, as the single layer nature means aggregate can be prised loose by wear and tear. The manner of laying the concrete, however, is very standard- using a damp proof membrane and a concrete pourer. After tamping, the aggregate is spread evenly over the surface and forced into the upper layer of concrete with a hand tamper.
Washed to Expose.
The second way of making this decorative concrete driveway style is the ‘washed to expose’ method. It’s perfect for heavy duty applications, as the aggregate is held very firmly into the concrete, unlike the surface dressed method. However, aggregate is expensive and the vast majority of the aggregate used in this driveway will never even be exposed, so it’s a matter of balancing durability and budget. You may want to create a basic layer of cement driveway, and pour over the more expensive aggregate cement in a smaller layer. As the decorative aggregate layer is layed, the aggregate is thoroughly mixed into the concrete inside the mixer. There’s a huge range of available aggregates out there to suit any taste. You can even blend them together to create the effect you want.
Once the decorative concrete is in place, you will reveal the aggregate by washing away the holding cement. The oldest and simplest, although not easiest, way to do this is by washing away the cement with a pressure sprayer and a scrubbing broom. This will expose the decorative aggregate. It’s best for smaller jobs. There’s also the option of using a chemical surface retarder sprayed immediately after placing the concrete driveway in Melbourne. This delays the setting of the cement paste, and enable the exposure to be done up to a day later. This enables a longer timeframe for larger jobs or during hot spells.see the website http://www.frasercoastchronicle.com.au/news/scooter-riders-face-big-risks/2559835/ for more info.
Whichever method you choose to apply to your decorative concrete driveway, there’s little wonder that exposed aggregate is becoming such a popular and dynamic choice for homes and business premises all over Melbourne, as it’s versatile and attractive.
