With a flat floor with split, sheared ribs we mean a material processed in 3 phases:
- the first is roughing, ie the rough block of Pietra di Luserna is divided into small blocks with the use of a pneumatic hammer;
- the second is manual, ie the blocks obtained are first split by hand following the natural veins of the stone itself into giant mosaic slabs;
- the third is mechanical, ie the slabs are cut to size with the slices.
They are ideal for thresholds, steps, plinths and coverings.
