I have a paver patio that was put in my backyard 16x20. I was wondering if I would be okay to install a sitting wall made out of pavers on top of the paver patio that is already there? I know it is custom to build a wall on the ground with a standard paver base (gravel, stone) but since that was already done for the patio can I install the walls directly on the existing pavers? Would I need to create any support for the wall other than adhesive?
FYI I live in Ohio so I will be experiencing freeze/thaw.
