Our Nero Porcelain Paving features a range of black and charcoal tones throughout the surface, offering a bold and striking finish to any garden or patio. Porcelain paving tiles are man-made, vitrified paving which is non-porous and extremely durable. With a slip-resistance rating of R11, porcelain tiles will retain their grip underfoot, even when wet and as a non-porous stone, they won’t allow moisture to penetrate the surface which will help to prevent any build-up of moss or algae, saving you time and money!
