Porcelain landscape tiles are also ideal for resurfacing an existing concrete patio. Porcelain tiles will give your landscaping an unbeatable aesthetic quality. Porcelain tiles are the ultimate low-maintenance material when used outdoors. Unlike concrete pavers, porcelain tiles will not effloresce, which means it will not produce a whitish buildup that is very difficult to remove. And unlike many stone pavers, they will not be damaged by the use of household cleaners.
