Porcelain pavers are twice the thickness of most tiles, and they often complement a 10mm porcelain range, so the same product can be used inside and outside.. They are the ideal paving solution, they will not stain, fade and require no treatment. Easy to install, porcelain pavers and slabs can be laid dry on sand, grass, or gravel, or they can be laid on concrete with adhesive, like a traditional porcelain tile. Another alternative is to lay them using adjustable, raised supports with open joints allowing for drainage.
