Hi buyer，
Thank you for your time to the mail.
Yes, these tiles are made of hard rubber and are hollowed out for easy drainage.
Hope this helps.
Best wishes, Jennifer Customer Support

No. It has holes in it so the water actually goes down to what ever you have below the tiles.

It is not solid it does have a pattern with holes so if water gets on it the floor underneath will get wet. I have it on the back porch under an awning. However, I do spray it off.
