## Frequently asked questions

### What is concrete grinding?

Concrete grinding is the process of using an abrasive tool such as a concrete grinder to remove irregularities and imperfections from a concrete surface. This is a finishing tool not to be confused with heavy duty grinding for large uneven surfaces.

### How much will a concrete grinder remove?

A concrete grinder will remove a minimum of 1.5mm from your concrete surface with each pass.

### How do I break up concrete?

Breaking up concrete is no mean feat, but much easier when you have the right gear. To break up concrete, first ensure you have the correct safety equipment and you understand the thickness of the concrete you are wanting to break up. When you are ready with your selected concrete breaker tool, fit a breaker bit and begin breaking up concrete from the corners of the slab you are working on.
