Exposed aggregate concrete is durable and long wearing. An exposed aggregate driveway can last up to 30 years with the right care and maintenance. Exposed aggregate concrete, when used around swimming pools can be lower depending on the chemicals used in your pool but can still be expected to last 15-20 years or longer with proper care. 

Exposed aggregate is created by washing back the top layer of concrete to expose the decorative substrate, creating a detailed, textured finish.  This process allows for an aesthetically pleasing result that also makes the concrete highly durable and non-slip. Exposed aggregate is available in a range of colours and textures depending on your needs and preferences. 

One of the benefits of exposed aggregate is that it does not require extensive maintenance to retain its appearance. It is recommended to keep your driveway or outdoor area clean by sweeping or hosing it down regularly. For more stubborn stains such as oil or tyre marks, cleaning with a high pressure washer using hot water and degreaser are effective. Exposed aggregate will also need to be resealed every few years to continue to protect the surface. 

Exposed aggregate concrete is more expensive more than standard or plain concreting due to the additional materials, labour and expertise in technique required to achieve a high-quality finish. The cost of concreting services will also vary depending on the contractor you engage for your project, the quality of the materials used and their level of experience. There are many advantages of exposed aggregate concrete that are not achieved with plain concrete so your overall cost should also be considered in conjunction with the results you hope to achieve. 

There are a few factors to consider when choosing colours for your exposed aggregate surface. Exposed aggregate consists of 2 main components – the base concrete and the aggregate. This means you will need to choose both a base colour and the size, texture and colour of your aggregate material. The choice of colour can also be based around the size of the area being concreted as well as the aesthetic you want to achieve. Our contractors are always willing to discuss options with you to help you find the right colour for your project. 

Exposed aggregate concrete is an excellent choice around a pool or spa. It provides a natural non-slip surface, even when wet and will not shift out of place like pavers or tiles. Concrete is also more versatile and efficient to install, offering more options and less disruption during the construction process. 

Concrete should always be given adequate time to set completely to ensure it remains strong and sturdy over time. The drying time required also depends on the total area and the thickness of the slab, as well as environmental factors during the drying time. In general, the surface can be walked on within 2 days, with vehicles able to drive on the surface after a week. Heavier traffic should be avoided for anywhere up to 30 days, after which the surface will be fully set and have reached full strength. 

Yes – exposed aggregate concrete should be sealed to protect it from damage, stains and wear and tear. A sealant will also enhance the appearance of your concrete, highlighting the colour and texture and providing a finished appearance. 

It is generally recommended to reseal your driveway every 1 – 2 years for best results. How often you reseal will be impacted by a number of factors including the original sealant used, the amount of wear and tear the driveway is subject to and the weather conditions. The more effectively the initial sealant is applied, the less subsequent sealant it should require so it is a good idea to use a reputable concreting company to install your driveway. 

Exposed aggregate is easy to maintain. Regular sweeping or rinsing down with a hose will stop dirt from building up and prevent stains sinking into the concrete. For a deeper clean a high pressure washer can be used with hot water and degreasing agent to remove stubborn stains such as oil or tyre marks. 

Exposed aggregate is ideal for commercial projects. It is durable and long lasting, and is able to hold up under high traffic from people or vehicles. It is low maintenance so is perfect for large areas including schools, offices, public facilities and more.
