Garage Floor sunk!! How do you fix that? How much?

[Samuel DeMass]

Hey BP,

This one is a little off the wall, but just curious if anyone else has dealt with this already.

Just when you thought you'd seen a few things, you walk into a garage that sunk 2-4"...it's bizarre!

The foundation of the house is solid, but it looks like the garage floor was attached to the outside of the foundation or poured at a different time, because it sank.  I think it was caused by some run-off issues with water.

The bottom line is I need to get it fixed.  Who does that type of work, and how is it done?

Do I need to get someone to jack-hammer it out and haul off the old floor?

Can they just pour a new layer on top of the old layer?

I appreciate your time and thoughts!

Cheers,

-Sam
