Reversible 16 in. x 16 in. x 0.75 in. Terra Cotta Brick Face/Flat Profile Rubber Paver

Used on the path my dog made, just dirt 7 years ago. They are still there, no movement at all. getting more.

I did not put anything under them. I just randomly put them as a path where my dog had worn away the grass 7 years ago, and they are still there. We just mow right over them. They have not shifted, cracked or anything. I really didn't think they would last, but they are still there. I plan on getting more. When I can afford it. They are expensive, but worth it.

Can these tiles be placed on grass?

According to the paver calculator on the product's Home Depot web page, you would need 279 pavers at a total cost of $1,389.42. To check this yourself (in case the per paver cost is different in your area - it's $4.98 in my area), just scroll down the product's page until you come to the calculator. Enter the 15 x 30 dimensions and the amount of pavers you need and the total cost appears.

You can secure it to a dirt area as long as the area must be firm and level before applying these tiles.

These are not heavy. I wouldn't recommend using them for weights. I recommend the large flat concrete pavers for their weight. I think they are 14'x14'???? I used them for a drive pad I created. They have been down for over 5 years. I few have cracked, but my Impala is sitting on them, and they are still durable.

As far as I know, it doesn't.

No

I don't see why not, they are for outdoors. The chair legs will go through if you are on the seams.

Hello, Yes you may install these tiles over a wooden deck.
