Sinking mud room

Have an interesting issue at my friend's house.

At some point a previous owner added a "mud room" on the back. Our intention is to clean it up and put up a piece of plywood to hang tools.

The interesting part is that it seems the concrete slab it sits on is sinking. I don't have photos (yet) but basically there's about a 3 - 4 inch gap under one wall where the slab is separating from it.

It's a small room (4' x 5' maybe) but I would like to be able to fix the gap in the floor if possible to help keep out unwanted furry guests, water, and so forth.


Is it even feasible to try to raise the concrete slab this was built on? Or just use a couple of pieces of wood and insulation to close the gap on the one wall? We're trying to keep this on the cheap, obviously.


Any advice would be great - thanks very much.

Pictures would definitely help but it sounds like the mudroom is not sitting on a proper footing which means it will keep sinking regardless of what you do.

Yeah, I figured that was probably the case. I'm going over Sunday to help clean it up so I'll get a few pics then. Thanks, though.

I see it all the time on pored raised porches, and breeze ways, garages.
99% of the time it was back filled with the wrong material and not compacted in layers.
