Heavier than you might think! I estimate about 40 pounds. I use a garden cart to move these - helps when you have multiple bags! Hope this helps!
Yes! Easy to pick up the poo, urine soaks through and the roundness of the pebbles don't hurt dog feet (I have had up to 6 big dogs - now only 3) and they seem to prefer the pebbles over grass. Hope this helps!
Alot. There is no weight on the bag but it is quite heavy. I would guess over 50 pounds.
I didn't notice chemicals, just a lot of dirt and mud that needs to be cleaned.
Age, Each bag covers approximately 3” within 1 sq ft. Depending on the depth you want you can calculate the amount of bags you will need Example: 12 x 12 = 144 sq ft 3” deep = 144 bags 1 1/2” deep = 72 bags I hope this helps Enjoy your project.
Maybe they would look more like the photo if they stayed underwater, so that could be a good idea.
Ask Home Depot. Many is spelled like this M-A-N-Y!
I assume you can (or other adhesive), tho it would require a LOT of adhesive, since there are a lot of small pebbles. Not sure what your end goal is - to keep the rocks from moving, or to have them all stick together, or to have a watertight seal, etc.????
