There are a few reasons why contractors cut grooves into concrete. The first reason is for aesthetics. Grooves can give concrete a more finished look and they can also be used to create patterns or designs in the concrete. The second reason is for function. Grooves can help control cracking, provide drainage, and improve traction.
The most common type of groove is the saw cut groove. Saw cut grooves are created using a circular saw with a diamond blade. The depth of the groove is determined by the depth of the blade and the width of the blade. Contractors will often make multiple passes with different sized blades to create wider or deeper grooves. Another type of groove is the core cut groove. Core cut grooves are created using a core drill and an abrasive wheel. These types of grooves are typically shallower than saw cut grooves and are mainly used for decorative purposes.
No matter what type of groove you need, cutting concrete can be a messy and dangerous job. It produces a lot of dust and if not done properly, can lead to injuries. That's why it's always best to leave it to the professionals!
