This technique involves removing the top layer of concrete to reveal the aggregate underneath, creating a textured and visually appealing finish.

Benefits of Exposed Aggregate in architecture

One of the main benefits of using exposed aggregate in architecture is its durability. The exposed stones and pebbles add strength to the concrete, making it more resistant to wear and tear. Additionally, the textured surface provides better traction, making it ideal for outdoor spaces such as driveways, patios, and pool decks.

Applications of Exposed Aggregate in architecture

Its versatility and aesthetic appeal make it a popular choice for both residential and commercial projects. The natural beauty of the exposed stones and pebbles can enhance the overall design of a space, adding a touch of elegance and sophistication.

To achieve the exposed aggregate finish, a special mix of concrete is poured and then the top layer is removed using a process called washing or sandblasting. This reveals the aggregate underneath, creating a unique and visually striking surface.
