WHAT KIND OF TILES ARE SUITABLE FOR A TERRACE?

I have to redo an outdoor entrance terrace, which is also driveway, of 20/30 sqm. It is located in an area where winters are very cold, with ice and snow; in summer, it is exposed to the sun for 70% of the day. Therefore, I need a material that is both resistant and durable. I was recommended a klinker because it is cheaper than a porphyry. Now I have a porcelain stoneware, but probably of poor quality, because the tiles are gradually breaking. What do you recommend?

Regarding your request, without the possibility of a live inspection, I can only make conjectures and hypotheses.

1) The cracks on the terraceare hardly ever due to poor tile quality. Often their development is due to a bad laying, which did not consider the dilatations and the structural movements that can be made by a terrace, exposed to -10 ° in winter and to +60/70 ° on the surface in summer. If the tiles have cracks or fissures that pass from one to the other, my diagnosis is more than a hypothesis.

2) You can use the highest quality and thickest tiles on the market, but if no expansion joints have been made, if a flexible and elastic glue has not been used to balance structural movements, if no installation has been made with double layer of glue, if no suitable waterproofing has been made, etc… your terrace will necessarily have defects. If only one of these things has not been done, the tiles will jump, crack and come off.

Please also note that all terraces are always at risk. In fact, abroad they no longer perform glued floors; they cover all the terraces with floating floors, which, at any time, allow you to go and restore any loss of waterproofing, without removing anything.
