After mining the granite stones, they will step into the next process.

Cutting the Huge Granite Stone into Block

You might know that the naturally occurring granite stone is large, and you will not be able to use it directly on the countertop. Hence it is necessary to cut this stone into blocks. Using the expanding or explosive motors, they will cut the stone into a large block.

After cutting, these blocks will go to the warehouse where they will be storing all these blocks. There is special machinery that they will use when cutting the blocks. During this process, the people involved will have to be very careful, as the block might explode and shatter in the worst case.

The previously cut slab will get polished well, and then the granite slabs obtained from the same granite block will be packed together and sent to the distributors. The main reason for packing all the slabs you obtain from one block together is because this will make the customers and the seller easily find the granite countertops with the same pattern and color.

After choosing, the fabricator will fabricate the slab according to the countertop in your house. They will cut the holes for the sick and the faucet.
