Concrete Grinding is a process that uses a piece of equipment and abrasive tooling to wear down or remove concrete toppings or concrete surfaces. This process is very common when refurbishing floors in commercial and industrial buildings. Most of the time, there are materials that need to be removed from the concrete before a new floor can be put down.
Concrete Grinders are very popular for this job.
Polishing Concrete is a similar process to grinding. The main difference is that there are multiple steps of grinding, which use finer and finer grits each pass. This begins to add shine to the concrete and make it usable as a finished floor.
