What is Exposed Aggregate?

The most popular decorative concrete is exposed aggregate concrete. While many types of concrete are mixed with aggregates to add to the durability of the mixture, the distinct beauty seen in exposed aggregate surfaces comes from the specific manner of laying the concrete.

To achieve the lovely and unique look of exposed aggregate, we use a high end product to remove the top layer of concrete to reveal the mixed-in aggregate. The kinds of aggregate available to create this type of concrete surface are almost limitless.

Where Can It Be Used?

Because of its durability, flexibility and stylishness, this type of surface can be used virtually anywhere. It is particularly popular for alfrescos, driveways, pathways, patios and school areas. As it’s a non-slip surface, it can also be used for pool surrounds or other areas that might get wet and slippery.

Our expert team create looks with more specific details by laying stones or other materials directly to the top of the concrete before the surface hardens. By using the exposed aggregate method, we assist our customers in creating a one of a kind blend to harmonise with the existing surroundings. The aggregate is mixed in with the concrete batch or set onto the surface for a truly individualised look.

We can help you work through the designing phase and offer you expert suggestions. As such, we’re completely confident you’ll love the finished product.

We have a huge range of different designs!

Exposed Aggregate Benefits

Exposed aggregate is more than just beauty and style. It is also durable, making it a cost-effective option for home and business owners in Perth. Here is an overview of its advantages:

  • Durable: Compared to normal concrete, exposed aggregate lasts longer. It is designed to endure high traffic and heavy vehicles moving down the paths. This is in compliance with AS 3600.
  • Stylish: Enjoy the visual benefits that can enhance the look of your property. No matter which type you choose, washed or honed, you can be sure it will meet your design expectations.
  • Flexible: This type of surface is customisable in every aspect of layout, colour, and design. The possibilities are endless.
  • Cost-effective: Sealer does not require yearly applications. Depending on the location and sun exposure, sealer reapplication can vary from three to five years.
  • Weather-resistant: Weather damage has always been the main concern with every type of material. Western Australia is generally hot and dry, but it is not a problem with exposed aggregate. We user a sealer for protection, along with other weather-resistant components.
  • Maintenance-free: It is long-lasting and does not have issues such as pebbles and sand that get between the pavers, tree roots popping out, and so on.

Over the last 20 years, concrete has come a long way. When you choose a highly reputable company such as Decorative Concrete WA, we ensure the exposed aggregate matches the style and colour scheme of your home.

Steps for Laying and Finishing Exposed Aggregate

Here's a brief outline of the basic process when laying and finishing:

1.) In order to come up with a design that's best suited to a customer's home or business, we sit down and have an in-depth discussion about the layout of their premises, their budget, the finish/surface they desire and more.

2.) Based on our detailed planning, we mark out everything with string lines and chalk lines. Water drainage is essential in 90% of concrete jobs, so we make sure we're prepared in the event of excessive rain. Once the earthworks (compaction) are complete, we install a strong SL62 mesh in all areas, including pathways.

3.) The exposed aggregate mix will then be placed. If the area is elevated or a long distance, we will use a concrete pump or line pump. Otherwise, we utilise wheelbarrows in normal circumstances.

4.) Control joints are then placed 25 to 30mm deep. This process is normally done within the first 12-16 hours of the pour.

5.) If a washed aggregate mix was poured, our team will be back the next morning to wash off the top layer of cement to reveal the aggregate. If a honed or polished aggregate mix was poured, then the concrete will be left for about a week to reach a completely hardened state to begin machining.

6.) It may take one to two days to properly finish the job. We use acid wash (hydrochloric acid) and water with a 1:10 or 2% ratio. This step is essential in removing all residues and contaminants. The result is a consistently evened out, beautiful looking surface.

We Use Only the Highest Quality Sealers

Making sure your new concrete exposed aggregate driveway, pool surrounds or walkway is properly sealed is essential to the life and beauty of any concrete work.

At Decorative Concrete WA, we give the same amount of care and attention to sealing your project as we give to every other part of the job. We use only the highest quality sealers available; those rated to keep out 99.5% of moisture. We will not use lower quality, less expensive sealers on the market, because we care about every detail of our craft.

Sealers come in two main types; penetrating sealers and topical sealers.

  1. Penetrating sealers absorb into the concrete, binding to it via a chemical reaction that takes place between the sealer and the concrete. The sealer is applied to concrete that is dry or slightly damp. The typical life span of penetrating sealers is five years.
  2. Topical sealers are, as the name suggests, coatings which stay on the surface of the concrete. These sealers are typically epoxy/urethane blends that work on dry surfaces. The topical sealers give a brilliant shine to concrete and have a life span of one to five years.
