I have an enclosed patio with a horrible concrete job that is also the footing for the exterior walls. Could i demo it out and put pavers? I think i would cut along the footing and keep it then put paver sand and pavers to make the new floor. There is electrical conduit that i will need to keep under the floor for the hot tub. That is why i want pavers in case i need to access it later. Does this sound do able?
