Thanks!

As G & S states, there is WAY MORE going on here than just 'cracks'. A concrete slab cracks...but they are normally hairline or spider cracks. You have BIG cracks running in straight lines (concrete doesn't normally do this....so what is CAUSING it to do this?????). And you have voids in your concrete. Something (from below) has damaged it SOOO badly that chunks have come out of it. Ouch!

I think you will need to put your flooring purchase on hold and call a 'wet basement' specialist that deals with damaged concrete slabs and moisture issues. They will deal with this...but it is going to cost the same amount (or more) as you had planned for the vinyl purchase + install.

To fix your basement slab, you will want to set aside at LEAST $5/sf...with the knowledge that it is very possible it will go up. I've seen badly damaged cement slabs with +++ water damage cost $10/sf or more to permanently fix.

Gasp! I know. I get it. That's not what you wanted to hear. At least I can say it here (and you can read it in private) so that when the quotes come in, you will be mentally and emotionally prepared to 'hear them'. You will not feel like you are being 'ripped off' if you start hearing some of these numbers come back at you.

Take a deep breath and start calling companies in your area. I can guarantee they have seen this before. And more than likely they have seen it in the same neighborhood as well.

Calling a local specialist now, will get a pro out before we do any more. Thanks all!

Marina, what ended up being the resolution for repairing your concrete?
