Ok so I ran out to Home Depot yesterday and picked up my PVC, Astro Turf, and of course a ceramic tile. Then I was out in the garden shop, checking to see if perhaps a rock might be something better than the tile, and I found this:
http://www.homedepot.com/p/Envirotile-10-in-x-24-in-Flat-Profile-Stair-Tread-in-Terra-Cotta-MT5000805/203061067It's made of recycled rubber and I was hoping to use it on top of egg crate for the basking platform instead. My mom was worried that Sheldon might try to eat it. I figured there was no way to gain access to eating it, as the eggcrate was going to be on the bottom of it and the only spot to really get at it would be when she came up the ramp. Still I was wondering what everyone thought here before I go ahead and use it.
Also, a thought occurred to me about the artificial carpet - Astro Turf -

I think this would be perfectly safe as it's used in areas that get wet all the time but I again wondered if anyone had any thoughts before I went ahead and put it in. I intend for the turf to go beneath the PVC (meaning it will be submerged at all times) to prevent scratching the glass.
