I have a very heavy planter box that measures 6' X 2' X 2' (L/W/H) filled with dirt and has 6 swivel casters to allow for rolling on my patio. I don't know exactly how heavy it is. Will the flagstone rubber tiles withstand the weight without depression points where the casters rest and will I be able to roll the box around?
Our Flagstone Rubber Pavers are dense enough that they can withstand any furniture or item on top of them without indenting while also allowing water to flow through them. So a planter or furniture will not lead any indentations in the pavers.
