I have a small concrete patio outside my back door. Over the last few years it appears to be moving slowly away from the house creating a 1"-2" gap. The patio is ringed by several feet of paver stone so I don't expect it to shift very far. I wanted to fill the gap with crushed limestone (for safety and aesthetic reasons) but my wife feels it will push the patio out or up. I have the same issue with some of the expansion joints in my driveway and I would like to do the same thing.
