One of my driveway slabs just rose 2" on one side, is that because of the drought? Or just coincidence? Are we supposed to be taking any precautions to your driveways or anything right now?

Not from here so this is all new to me. I have sprinklers but I'm noticing some of my slabs on the driveway on up on my pathway to my door have rose about 2" on one corner.

Just not sure if this is normal, if the ground is so dry it's shrinking? I have no idea.
