Groove-cutting machines
Concrete expands and contracts constantly as it is exposed to temperature changes, the moisture content in air and drying of cement which results in shrinkage. Due to this process cracks may develop on concrete surfaces, and it is nearly impossible to prevent these cracks but can be controlled. Making grooves
