Porcelain tiles can be installed on pedestals, which are support structures that raise the tiles off the ground. Pedestal systems are often used to create a raised floor or deck surface, or to level an uneven surface. They can be made from various materials, such as plastic, metal, or concrete, and are available in different heights and sizes to suit different applications. When installing porcelain tiles on pedestals, it is important to ensure that the pedestals are level and stable, and that they are spaced correctly to support the weight of the tiles. The tiles should also be cut to fit the pedestals properly and be secured with an appropriate adhesive.
