Could the original poster please clarify "Paver Base Panels"? I think I know what you are referring to but want to be sure.
First thought I have is what is the pattern of paver, can I reuse the cuts or was it laid on a 45 degree and have a ton of little triangles. Then I am (like others) concerned on why it has failed. If there was never a proper base to begin with you will need to redo entire project from scratch (I would do that anyways because even though there appears to be proper base depth who knows how or if it was compacted). If anyone ever asks me to ballpark a redo of a patio, figure almost double cost to do a new one because you have to remove entire existing patio area and save every brick vs digging up grade and disposing.
