The contractor shall install, diagonally with respect to the walls, new porcelain stoneware tiles of large size/format. Minimum standard acceptable sizes would be 90x90, 45x90, 30x90, 60x60, 40x40 or 48x48 cm. Anything less than 0.16 m² per tile is not authorized

The name “porcelain stoneware” indicates a non-glazed, dry-pressed, highly compact, ceramic product with high quality, technical specifications (these tiles are highly flex, graze, scratch, weather and chemical agent resistant) and have a very low porosity. Unglazed porcelain ceramic tiles are hard, dense ceramic tiles; of homogeneous composition throughout, deriving its color and texture from the materials of which the body is made and from the method of manufacture. Unglazed porcelain tiles are very tough and they are extremely vitreous and dense. They are a through-color product and recommended for very heavy traffic areas like hallways they may wear, but will retain their original color. Unglazed porcelain tiles are available in various finishes, from matte to high gloss, and some have textured finishes, made to imitate natural stone.

The minimum technical features of the porcelain stoneware are:

- Water absortion (ISO 10545-3) < 0.1%
