Quoted from rufessor:I think some of the commercial stuff may even come in glue down squares so you can easily fix anything that gets worn or whatever.
Yes, some of the commercial carpet does indeed come that way. I used 2' x 2' commercial carpet squares for my game room. They have a rubber backing and a sturdy low pile top. As part of the same order I got spray cans of glue made for use with the carpet - you spray a few quarter sized shots of glue on each carpet tile before laying it down on the concrete floor. I've never had a tile move out of place in the ten years or so that they have been installed. But if I damage a piece or carpet, I could take up just one tile and put down one of the spare tiles (yep, order some spares!). I have no problem moving pins around on my Harbor Freight lift table on this carpet, and it doesn't "bunch" up when rolling a pin around on the lift table like a traditionally stretched carpet with pad would do.
