What is Exposed Aggregate?
Exposed aggregate concrete is a popular type of decorative concrete that can be featured in numerous settings both indoors and out. The surface is made of ordinary concrete mixed with various kinds of stones and other materials. Our experts then use different techniques to wash away a few millimetres of concrete, exposing the other material. Many business and residential clients choose exposed aggregate because it can enhance the environment and is a durable and cost-effective option.
How is Exposed Aggregate Installed?
There are several steps to installing exposed aggregate concrete. While the process may sound simple, our installers spend years perfecting the techniques that create fabulous exposed aggregate surfaces.
1. Preparation- The site is cleared of any debris, the ground levelled, and concrete forms put up.
2. Mixing- A combination of cement and water is mixed and may contain various aggregate materials.
3. Pouring- The freshly mixed concrete is poured into the forms.
4. Adding Aggregates- If the aggregate materials are not added when mixing, they are scattered across the wet concrete surface.
5. Treating the Surface- The top layer of concrete is removed to expose the aggregate materials added to the surface or mixed into the concrete. There are three ways this takes place,
- Surface Retarder- A chemical that slows the concrete’s setting is applied and left overnight. The next day, the top layer is washed away.
- Brushing and Washing- The surface is sprayed with water, and a broom is used to wash away the surface mortar.
- Abrasive Blasting- Fully hardened concrete is blasted with abrasive materials to remove the surface. This method is rarely used as it can damage the aggregates and dull the finish. Curing- To completely cure, the exposed aggregate must remain undisturbed for several days.
6. Sealing- After curing, a sealer is applied to the surface. This protects the exposed aggregate concrete and enhances its appearance.
Is Exposed Aggregate Expensive?
When asking the question, “Is exposed aggregate concrete expensive?” it is necessary to view the prices of different types of concrete relative to one another. For example, exposed aggregate concrete has a higher price tag than plain concrete. However, it is considerably more affordable than stamped or coloured concrete.
How Much is Exposed Aggregate?
One of the first questions people considering this kind of surface ask is, “How much does exposed aggregate cost?” Generally, you can expect to pay between $100 and $150 AUD per square meter. There are several factors that help to determine the exposed aggregate’s cost. These include,
- Location- If the site is difficult to access, it is hard to prepare, or if it is in a densely populated area, the project may have added costs.
- Design- A design that is intricate and requires more materials and specialised labour will have a higher price tag than a simple exposed aggregate.
- Materials- Choosing unique aggregate materials such as shells or crushed glass will raise the price of the project. Simple types of materials will cost less.
- Extra Features- Adding fancy borders, coloured pigments, or special secrets will increase the exposed aggregate’s cost.
Is Exposed Aggregate Concrete Worth the Price?
Seven Benefits of Exposed Aggregate Concrete
1. Cost-Effective: Exposed aggregate concrete is a relatively inexpensive choice for residential and commercial uses. While the up-front costs can be higher than those of other materials, you will find that aggregate saves money over time. The installation process requires fewer materials, which saves money. Additionally, the exceptional look of exposed aggregate tends to add value to a property should you plan on selling at some point.
2. Low Maintenance: An exposed aggregate surface inherently requires less cleaning because the texture hides stains and dirt well. The steps to maintain an exposed aggregate surface include,
- Regular sweeping with a broom or a leaf blower
- Inspect the surface for stains and spot clean right away.
- If the surface is unusually dirty, a pressure washer on the lowest setting will remove embedded dirt.
- Apply a high-quality sealant every few years to ensure the concrete’s durability.
3. Long-Lasting Beauty: Exposed aggregate concrete stays beautiful for many years. The textured surface plays a significant role in maintaining beauty because dirt is less noticeable. Additionally, the coarse surface resists wear and retains its beauty.
4. Customisable and Versatile: Installing exposed aggregate concrete allows a great deal of choices because there are a number of ways it can be tailored to your area. Some of your options will include,
- Aggregate Variety- There are a multitude of aggregates available to add to your concrete. Pebbles, shells, quartz, granite, and recycled glass are popular options in exposed aggregate.
- Colour Customisation- If you want a unique colour palette, you can request tinting of the cement used to hold the aggregate.
- Texture Control- You can choose the aggregate used for your surface, but you can also determine if you want a coarse or fine texture.
5. Environmental Benefits: Exposed aggregate concrete is environmentally friendly for several reasons.
- Reduce Landfills – Exposed aggregate is frequently made using materials that would go to landfills.
- Sustainable- Concrete is a sustainable material that is easily recycled.
- Local- The materials used in exposed aggregate often come from local sources.
6. Slip Resistant- Exposed aggregate’s texture makes it naturally resistant to slipping. This quality makes it a popular choice for pool decks and outdoor walkways.
7. Durability- The textured surface of exposed aggregate enhances its ability to withstand harsh weather conditions, extreme temperatures, and consistent wear and tear in heavy traffic areas.
