Hold on here Rob, I am listening and following through on this with few opinions and nothing else. I too have wondered how stones (especially those veteran stones) set in concrete 60 and longer years ago have lasted. I have tried floating slabs which snapped before they compressed the stone, appears cheap concrete is deadliest. I have issues on both sides of the fence, your side, too. I don't have all the answers, and I use a few things learned on this list, altough I don't use any of the products widely recommended. I have seen stones set in concrete by the WPA and are still there. I have seen stones where its been done elsewhere and failed. Believe me, I am far from "great". I will make a trip to your graveyard and look for myself, I don't think looking at any pics would have helped me anyway. I have always poked my nose into work projects that are mentioned on here. And I am going to respect views on all sides, I don't know that there is an expert out there, but I'm here to learn more. Terse as these discussions have gotten, I'm not out to get anyone. I'm all ears to everyones voice. Thanks, Lee Creed
