Howdy- I am working on a paver repair job and I would like a little advice if you dont mind. The current paver patio was built on top of an existing concrete patio. Because of a pipe leak under the old patio some pavers had to be torn up as well as a section of the old concrete patio (about a foot wide). There is a layer of sand under the pavers that were left undisturbed. I plan to fill the void where the concrete used to be with compacted b-19 and then add sand. My question is...how much sand? I know new construction is 1" of sand but there is only around 1/2" under the undisturbed pavers that I need to match up to. Do I just make them level with the existing pavers or do I leave them higher to allow for settling? Should I mess with Paverbond or anything else or should I just use regular paver sand? Any tips and or advice on the best way to put this patio back correctly would be greatly appreciated. Thanks!
