Perhaps the most obvious appeal of exposed aggregate is its beautiful decorative effect. With a wide variety of size, color and texture variations, every exposed aggregate installation is unique. The surface creates the perfect complement to your home or business exterior. The stones’ varied shapes and sizes add depth to your concrete. Exposed aggregate is visually interesting, especially when you choose colors that are unexpected for concrete. Even better, maintaining that look is a breeze you only need to hose the concrete down with water every few weeks.
