What type of finish is created by removing some of the concrete to reveal the rocks beneath?

The type of finish created by removing some concrete to reveal the rocks beneath is known as an exposed aggregate finish. This process involves washing away the surface layer of the concrete to unveil the aggregate materials, such as stones, pebbles, or gravel, that are embedded in the mix. The result is a textured surface that highlights the natural beauty of the aggregate, making it visually appealing and often used for driveways, sidewalks, patios, and pool decks.

An exposed aggregate finish is popular because it provides both durability and aesthetics, offering a non-slip surface while enhancing the overall design of the concrete. Additionally, this finish can be customized further by selecting different types of aggregates, colors, and sizes, allowing for a variety of decorative options.

In contrast, the other finishes listed are created through different methods: polished concrete involves grinding and polishing the surface for a sleek look, stamped concrete uses molds to create patterns mimicking other materials, and textured concrete is achieved through various techniques to produce patterns or textures on the surface without revealing aggregates. Each of these finishes serves distinct purposes and aesthetic goals in construction and design.
