The Resistant range tiles have been developed for the creation of chemical resistant flooring using the vibratory procedure. They are are made from 18.5 mm thick dry-pressed ceramic fine stoneware, as per DIN EN 176.
The tiles are distinguished by their good optical and hygienic characteristics:

• The reverse sides of the tiles have a profile, with a consequent improvement in adhesion. The tiles may be laid in abutting form, using the vibratory method, with their geometric shape providing a clean jointing appearance.
• The external shape of the tiles is that of a pyramid frustum, ensuring an uninterrupted, even joint with defined width.
• The uninterrupted joint is an aid to the durability of the grouting material.
• The special design of the central area of the flanks of the tile creates an open channel on the underside of the tile to the opposite side. This aids the ventilation of the grouting and base and supports the closure of grouting and base.
• The geometry of the pyramid frustum provides good laying characteristics, as it eliminates the risk of laying tiles on protrusions, and consequently that tiles that have already been laid do not rock.

The tiles with profiled surfaces are offered where the anti-slip groups R11 to R13 are requested.
