Drilling

The process of producing our blocks begins with drilling. Holes are firstly drilled both vertically and horizontally, and then the required diamond wire is inserted to cut blocks out of the solid mountain.

Sawing

The sawing process starts by connecting the diamond wire to an electric engine. The diamond wire cutting tools then drill into the mountain, rotating to achieve a clean cut.

Extraction

After the sawing process, the large segments of stone are pushed to the ground onto a soft bed of rocks to ensure a safe landing. These big blocks measure approximately 10 x 15 x 2m and weigh roughly 100 tonnes. The finished cut cubes are taken out of the mountain to be prepared for sizing and transportation.

Utilisation

The first quality check concerning colours, veins and cracks is done straight after the extraction. This is done by a manual inspection of the stone after spraying water on the surface.

Formation

After determining the use of the block based on its colour and quality, the blocks are then formed.

Quality control

The formed blocks are then inspected a second time to ensure the right colour and quality classification has been given.

Transportation

The blocks are finally put in position for further selection and transportation around the world. Blocks vary in size from 2 to 40 tonnes and the dimensions are up to 3.5 metres long and 2 metres high.
