Our new pool has some settling of the deck, most notably at the back of the yard. There is a slab that has sank on one end considerably. It's not directly attached to the coping or pool, there is a flowerbed inbetween. I am thinking of trying to fix it myself by digging under the low end, using bottle jacks to raise it back up, and adding either concrete piers or stacked cinder blocks for footings. Has anyone ever tried something like this?
