Re: Wheelchair flooring
Another option is lightweight concrete. It can be poured over a regular wood subfloor, with proper underlayment material. Opt for infused color rather than a stain, as it will be much more durable and won't show wear.
This will likely be the most durable and may be the most expensive, with the possible exception of tile (depending on the tile). It can be stamped to give the impression of tile or rock, thought that makes it rougher.
A similar option is terrazzo (it's Italian!) which is poured concrete that is then ground down to expose the aggregate. When colored aggregate is used, it can be very striking.

I have read several books on various home improvement topics. I do not have any current code books I can refer to. I was an apprentice plumber for two years.
