Homogeneous characteristic of the porcelain stoneware in comparison with standard ceramic tile (not acceptable in this project)

2.9.3 Porcelain Stoneware (large format)

Some of the internal floors of the school are provided with large format ceramic tiles. The scope of work of this contract is to leave and respect the existing tiles as much as technically possible and to provide new porcelain stoneware tiles in all locations of the ground floor and second floor, currently without these large ceramic tiles. These new tiles:

- Shall have the same size as the existing tiles

- Shall have higher quality, as described and required below

Porcelain stoneware tiles shall have the same size as the existing ones, with 8 mm minimum thickness. It must be noted that the price for porcelain homogeneous stoneware ceramic tiles is at least 50% higher than regular ceramic tiles. The contractor shall provide matching wall base board from the same model as the tiles. Cutting the tiles to provide the wall base is not authorized.

Porcelain stoneware is a ceramic with a compact, hard, colored and non-porous body. This is also called “grès” porcelain. Tiles shall be homogeneous or non-glazed. This means that all the material of the tile is made of the same material. If we cut a tile, there would be no difference between the bottom, the top of the middle of the tile. The terms “porcelain stoneware” or “grès” means that the ceramic body of the tile is extremely vitrified, that is to say compact, hence the exceptional great resistance. The result is a lean clay body, little refractory, fired in a kiln (at 1200-1400 C°) until it reaches a non-porous vitrification and a complete water-proofing.

The new ceramic tiles shall be high quality, provided with the following technical features:

- Size: Same as existing tiles to remain as much as technically possible

- Thickness: Minimum 8 mm

- Scratch hardness of surface (Mohs) >8 (according to EN101)

- Resistant to impacts: Complies with ISO 10545-5

- Water Absorption: Tested by ISO 10545 - 3 ≤ 0.5%

- Deep abrasion resistance: Tested by ISO 10545 – 6: Max 175 mm3

- Frost resistance: Tested by ISO 10545 – 12: Tiles must not produce noticeable alteration to surface

- Chemical resistance: Tested by ISO 10545 – 13: Tiles must not produce noticeable signs of chemical attack

- Friction coefficient (slipperiness): Non slippery. Tested by ASTM C 1028 ≥ 0,60

Tile installation shall be done following manufacturer’s instructions and recommendations. All floors shall be perfectly leveled. In the toilet room the floors shall be sloped towards the new floor drains to be provided as part of this contract.
