What is exposed aggregate?
Exposed aggregate is a type of decorative concrete that involves removing the top layer of concrete to reveal the natural aggregates (such as stones, pebbles, or shells) underneath.
What are the benefits of exposed aggregate?
Exposed aggregate is a popular choice for outdoor spaces because it is durable, slip-resistant, and can add visual interest to a space. It can also be customized with a variety of colors and aggregates.
How is exposed aggregate installed?
To install exposed aggregate, the concrete is poured and then a chemical retarder is applied to the surface to prevent the top layer from setting. Once the concrete has cured, the surface layer is removed with a pressure washer or other equipment to reveal the exposed aggregates underneath.
What types of aggregates can be used for exposed aggregate?
A variety of aggregates can be used for exposed aggregate, including stones, pebbles, shells, glass, and even recycled materials like crushed concrete.
What is the maintenance required for exposed aggregate?
Exposed aggregate requires regular cleaning to maintain its appearance and prevent staining. This can be done with a pressure washer or other cleaning solution. It's also important to reseal the surface every few years to protect it from damage and wear.
How long does exposed aggregate last?
With proper installation and maintenance, exposed aggregate can last for decades. However, the lifespan can vary depending on factors such as the climate, usage, and quality of the installation.
Is exposed aggregate slippery?
Exposed aggregate is generally slip-resistant, as the exposed aggregates provide traction for foot traffic. However, it's important to take precautions and avoid walking on the surface when it's wet.
Can exposed aggregate be used for indoor applications?
Yes, exposed aggregate can be used for indoor applications, but it may require a different installation process and sealer to accommodate indoor conditions.
Is exposed aggregate more expensive than traditional concrete?
The cost of exposed aggregate can vary depending on factors such as the type of aggregate used and the complexity of the installation. In general, it can be more expensive than traditional concrete, but the added durability and aesthetic value may be worth the investment.
Can I customize the appearance of exposed aggregate?
Yes, exposed aggregate can be customized with a variety of colours and aggregates to achieve a unique look. Talk to us about your options for customization.
Importance of Sealing Concrete: Sealing concrete surfaces can help protect against damage from moisture, staining, and other factors that can cause deterioration over time. It can also enhance the appearance of the surface and make it easier to clean and maintain.
Excavation is typically done with the use of heavy machineries, such as excavators or Skidsteer bobcats, as well as hand tools like shovels and picks. Proper excavation techniques are important for ensuring the stability and longevity of the finished concrete structure, as well as minimizing the risk of accidents or damage to surrounding structures.
The subgrade is the foundation layer, made up of compacted soil, crusher dust or road base aggregate. Its quality directly affects the overall performance of the concrete structure, as well as its longevity and durability. Evaluating the subgrade's properties, such as its strength, stiffness, and moisture content is crucial before constructing a pavement on top of it. Proper preparation and improvement of the subgrade can prevent concrete distress, such as rutting and cracking, which can lead to expensive maintenance and repairs. In summary, the subgrade plays a critical role in ensuring the long-term performance of a concrete system, and it is essential to give it due consideration during construction.
