I just bought a house with a concrete pool and the deck slabs have heaved. There was also a leak at the back of one of the slabs (the one that heaved the most) and while digging down to the pipes I did not run across any gravel, so it appears who ever poured the slabs did not do a proper job.
Since all the slabs have settled or heaved at some point, the previous owner's response was the fill the growing void with some sort of rubber caulk stuff. The "stuff" is still pliable, but it did not bond to the deck or the beam / tile.
Since I am in Michigan, my first thought is why in the heck would you even make a cantilevered deck like this? Any slab like that is going to move at some point, and it seems like a coping would help isolate the slabs from messing with the tile / pool edge.
Any suggestions as to the best course of action would be greatly appreciated. My first thoughts are to cut the slabs about 16" from the pool edge and have a proper coping put in, as well as new tile. Then I could break up the remaining slabs and install a new deck of some sort (undecided at this point).
Also, after looking closely at the photos I took, it seems the current tile is a little high. It looks like the top of the tile is above the beam. Is this typical?
I have more photos too, but it seems the limit is 3 per post.
