Do everything it takes to avoid these, learn from our experience. We had this type of plastic tile floor on our court in Gießen for about a year. It was terrible, theres nothing good about them! The court was unplayable for most of the year.
The slightest bit of rain made it slippery as hell. In addition to that the capillary force kept water between the tiles and the surface below the tiles. Every time you rolled over it, water was squeezed on to the court again, even on days it seemed playable at first glance . Thus, ten minutes of rain left the court unplayable for days or even weeks.
In springtime autumn and winter, the dew was enough to trigger the mentioned effect, leaving the court unplayable no matter how sunny the days were.
The few instances when it was hot enough for the court to dry throughout, the court saw another problem: The tiles extended and shrank so heayily on sunny days, that lines of tiles were pushed up and formed ridges. You could roll over them with your bike, but the ball would jump or get deflected.
The city put the tiles on the court due to one hockey player pushing for it, the day we were allowed to rip them of was a great pleasure.
tl;dr
HAD THE TILES ON OUR COURT, WORST POLO SEASON EVER.
