Read OnConcrete Milling is the process that involves removal of upper layer of concrete to obtain a smooth surface. Due to faulting and rutting of wheel studs, the upper layer of roads becomes uneven over time. Some of the areas that need milling are; roads, pavements, bridges, parking lots and sidewalks. The paved surfaces, thus, needs to be renewed ...
Read OnConcrete 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.
