Pavement cubes in Prague

I noticed that sidewalks in Prague are predominantly paved by the same types of stone/concrete cubes, whose size and shape might cause (or at least less effectively prevent) the underlying layer to gradually deform over time.
I also saw a construction worker manually put one cube next to another to pave a surface.
So I guess these cubes have low enough manufacturing/material costs (via economy of scale) without too high manual labor costs (low hourly wage for construction workers and/or the curved streets are less amenable for machine construction).
