cementbasalttactile

“Pietrino Grezzo 25 Bugne” tiles are so economical and strong, for years they have been used for urban pavements. As their name suggests, “Rampe” tiles are used almost exclusively to pave the ramps of garages and the like because of their shape with diagonal lines. PIETRINO/RAMPE - COMPOSITION ANALYSIS About half the thickness of “Pietrini 25 Bugne” and “Rampe” tiles is a vibro-compressed agglomerate of finely crushed natural porphyrys and basalts mixed with hard stone powder and PTL 425 cement. The bottom layer of these tiles consists of a mixture of silica sands and PTL 425 cement.
