Exposed aggregate is a type of ornamental concrete mostly used for driveways, sidewalks, patios, and other outdoor places. This design is achieved by removing the top layer of cement paste and exposing the underlying aggregate. Your chosen combination of sand, cement, and decorative materials like stones, pebbles, granite, or gravel can be used for the top layer. There are many different textures and sizes to pick from. Using this paving style, you may coordinate your exterior with your home’s overall design.
