my backyard isn't leveled. And half of the weights i make out of concrete end up uneven, which makes them useless since 1 half is thick, the other half is real thin. I thought about letting the concrete dry in my bedroom where i sleep. Since it's in buckets, my floor will stay clean. But how toxic are the fumes? I don't want to risk my health. Thank you for reading.

On a concrete front walk that's probably 30 years old, 1 panel has sunk a little (3/4" of an inch?) and water would pool there for a bunch of years now. I (foolishly??) got the bug in me to fix it. I dug under the low corner and Using a car jack (1 1/2 ton cap) I lifted it almost level with the panel next to it. (wasn't able to get higher than that - the jack was straining / really hard to pump it up more / afraid I might bend the lever on the jack. I started realizing - even if I get it level / higher (to allow for settling).... then what? What do I do to keep the panel up / allow for settling. And there;s a gap now between the bottom of the concrete and undisturbed dirt... (yeah, it's just dirt under it? I thought there'd be an inch or 2 of gravel?) Oh, and how to get the jack out THEN fill the area (taking the jack out = the corner will sink? Any thoughts on the panel weighing more than 1 1/2 tons? Or is it likely binding against the next panel? YES, I did look around a while ago for a company that does this work, but no one I found was interested in a small homeowner job like this. THANKS!
