Exposed Concrete

What is ‘exposed’ and ‘honed’ concrete, and how does it differ from traditional methods such as brick paving?

Exposed and honed concrete are two popular landscape finishes in Perth, that differ from traditional methods. The colour choices of exposed concrete offer greater versatility, consistency, and integration possibilities compared to brick paving, making it an attractive option for outdoor paving where design flexibility and modern aesthetics are desired outcomes. Exposed concrete is known for its durability and long lifespan, maintaining its colour and appearance over time with minimal maintenance.

So, what is exposed concrete?

Exposed aggregate concrete is created by removing the top layer of cement paste to reveal the aggregate (stones, pebbles, gravel, etc.) underneath. This process involves pouring regular concrete and then using various techniques to expose the aggregate. It can be achieved through washing, brushing, or using chemical retarders to expose the aggregate.

Exposed Concrete

Exposed aggregate concrete provides a textured and visually appealing surface due to the exposed stones or pebbles. It offers better slip resistance compared to traditional smooth concrete finishes, making it suitable for outdoor areas such as pool surrounds, where slip hazards might be a concern.

The exposed aggregate concrete can come in various colours and sizes of aggregates, allowing for customization to suit the aesthetic preferences of the homeowner or designer.

And what is honed concrete?

Honed concrete is a smoother and more refined finish compared to exposed aggregate concrete. It involves grinding the surface of the concrete to a uniform level, resulting in a flat and smooth surface. The process typically involves multiple passes with progressively finer grinding tools to achieve the desired level of smoothness.

Honed concrete provides a sleek and contemporary look, making it a popular choice for modern outdoor spaces. It offers a more uniform appearance compared to exposed aggregate concrete and is often chosen for its minimalist aesthetic.

While honed concrete offers a smooth surface, it may not provide as much slip resistance as exposed aggregate concrete, especially when wet. However, anti-slip additives can be incorporated into the sealer to enhance traction.

How are they different from traditional outdoor paving?

Traditional outdoor paving in Perth often involves materials like bricks, pavers, or natural stone, which are laid individually or in patterns on a prepared base of sand or gravel. These materials typically offer a different aesthetic and texture compared to exposed or honed concrete.

Exposed and honed concrete, on the other hand, are poured as a single slab and then treated to achieve the desired finish. This can result in a more seamless and contemporary look compared to traditional paving methods.

Additionally, exposed and honed concrete can be more cost-effective and easier to maintain than traditional paving materials, making them attractive options for outdoor paving in Perth and other regions.
