Concrete milling is a process that strips layers of concrete from roads, bridges, parking lots, and other paved surfaces to create a smooth surface with plenty of grip. Even though concrete surfaces that have been milled are finished and level, they need maintenance over time, in order to make sure they're safe and well-cared for. ...
