A stone alone: There’s one in every family. Within Techo-Bloc’s family of paving stones, the Antika paver stands out as an unusual stone with inimitable charm. Antika pavers are like snowflakes: no two are quite alike. Their asymmetrical profile confers to walkways and patios all the charm of an ancient cobblestone courtyard. Antika pavers can stand alone or be outlined by a beautifully sculpted curbstone.
