Rough concrete is a type of concrete surface that has not been smoothed or finished after pouring. This texture is often achieved by using a specific type of aggregate or by not using a finishing tool. Rough concrete is commonly used in construction for foundations, sidewalks, and other structures where a non-slip surface is desired. The rough texture of concrete can also enhance its grip, making it suitable for outdoor areas like driveways and patios. Additionally, rough concrete can be more cost-effective than polished surfaces, as it requires less labor and materials to achieve the desired finish.
