Hi CB thank you for your recent inquiry with The Home Depot. Upon further research I was able to determine that the item is able to be install over grass as long as the grass is cut short enough. I hope this information helps. We appreciate your business and look forward to serving you in the future.
The tiles work great on a concrete patio. While it can handle minor variances in levels, if it really unlevel you may want to level it off before installing the tiles.
Most definitely. Very good quality.
The key here is the size of the rough spots. If they are > 1/2" in size/depth you want to fill them in before laying the tiles.
Yes, using an electric saw, you can cut these to fit an existing deck.
Yes you can put furniture on top. They should not get damaged but of course you always want to be careful regardless.
No it does not.
These are made of PVC, I used a jig saw and it worked well.
The XL tiles have “legs” underneath that may puncture the roofing material. You’ll want lay a protective barrier between the tiles and the roof.
