A 30% chance of afternoon showers turned into an inch of morning rain on my concrete garage slab. I have pits from drops from the above subfloor, foot prints, some ridges from the visqueen we eventually just had to put over the top. The foot prints and ridges are probably 1/16- 1/8 deep. We poured at 8 am, and were out there til 11 pm pushing around a layer of soup trying to just keep thinning it out, drying it out, but the rain just kept coming. Put a bag of portland cement on it and kept working that in(right or wrong I don't know). But I am thinking I will lucky if the whole top 1/8 inch doesn't just eventually crack and peel off.

I am sick over this, can you grind it down? That will make it pretty rough I am guessing. Will epoxy(which I know is expensive as heck) fill stuff in and smooth it out?

Should I just live with it for a while then lay down some wire mesh with some pex tubing and pour another slab over it and have radiant floor heat?

I could just cry right now.

So if you have done any types of repairs to concrete, or seen anything like this, or know of any products I could take a look at, let me know. Because right now, my shop floor is @#$%#$^.

With all that water your concrete is probably garbage won't support any kind of weight. I'm thinkin you are probably gonna have to start over.

bad deal, happend to me on my 25x50 ft patio a few years ago.

yep, top 1/8 inch broke up like peanut brittel. if you find a fix let me know. i tried to re-surface it but it does the same thing after the winter is done with it.

How long was it before the top peeled off? Weeks, months, or after winter?

I really thought i had lucked out and all was fine, cause for 8 months it looked good. then after the snow melted off i had a heck of a mess.

I dont know what to do with it, i cant afford to tear it out and pour it again .

drahthaar...check w/home depot type place/contractor supply or concrete mixing plant...you may be able to seal w/epoxy or concrete sealer...otherwise you may have to grind down to solid set concrete.

From all that I have read, it seems that my best "bet" is going to be to put a grinder over it, get that bad top layer off and epoxy the whole thing. Its going to cost me the grinder rental and another 800 bucks for the epoxy kit for a 28x40 shop.

I am waiting for a reply from the guy about waiting until next spring, or just waiting the 28 days(that is what they recomend for new concrete) then doing the epoxy before it all comes apart.

How about a Rhino lining garage floor?

 

[drahthaar]

Hmmmmmm, haven't heard of that. Will look that up right now.

 

[rosco]

not a bad idea, since its indoors, grind it down then spray it with bedliner. but rhino lining will cost 5x what it will to epoxy it. you can get roll on bed lier that may work, but i dont know how durable it is compared to rhino or other spray on liners.
