Groove cutting is a technique used to create precise cuts in concrete to control cracking and improve safety. It's often done using diamond-tipped saws or specialized machines. 

Purpose 

• Control cracking: Allows concrete to expand and contract without cracking
• Improve safety: Adds texture to concrete surfaces to improve grip
• Improve functionality: Creates channels for water flow and facilitates the installation of equipment

How it's done

1. Concrete is cut with a diamond-tipped saw or specialized machine 
2. The grooves are filled with a sealant like polysulphide or bitumen 

Benefits 

• Enhances the structural integrity and lifespan of concrete surfaces
• Improves safety by reducing slip hazards
• Prevents pooling and ensures effective drainage

Safety

Groove cutting machines can be dangerous if used without proper inspection. It's important to wear appropriate safety gear and follow the manufacturer's instructions.
