Hello all, new to the forum. When my garage was built, the amateurs poured a slab of concrete over some crushed stone with no footers or even rebar, just a slab of concrete. They built my 2 car garage on it. Well, now the slab has cracked down the middle and is sinking on both sides. The only option I have come up with is this: Score around the inside perimeter, cut and remove the floor inside. Then, with the concrete remaining along the sides that is holding up my garage I will drill holes and run a system of re-bar through them and pour new concrete inside. Also, I will dig in the corners down a few feet to install some supporting footers. Will this work? Thanks in advance.
