Designed for flooring terraces or garden borders, DeckingStone is the Pietra Extraforte paving slab, designed as a natural stone alternative to the classic wooden plank. The slabs, available in two finishes, "sandblasted" or “flamed”, are 4 cm thick and measure 18x150 cm or 18x300 cm. They can be laid traditionally, applying the necessary adhesive straight onto prefabricated screed with grouting, or by using height-adjustable supports for raised flooring.
