Hello,

I recently poured a slab in my basement to support a new Oil boiler (approx 600lbs). The slab consisted of 13 bags of 80lb sakrete and it's about 5 inches thick. The room was an old sauna that's being converted into a boiler room and it was very difficult to work in there. It's been about 36 hours since I finished and I started to notice a few blisters at the surface of the slab. My question - Do blisters compromise the integrity of the slab? I'm not that concerned about the look, but am very concerned about the strength. Any advice on what to do with this? The boiler is supposed to be positioned on Tuesday. Thank you very much in advance!

"Do blisters compromise the integrity of the slab?"
Yes because the blisters are telling me you made the cement too soupy.
Didn't you reinforce it with anything?
I wouldn't set that boiler on it for at least a week. Don't forget they aren't going to gently set it on the slab they are going to basically slide it on.

Thank you for the response. There are about 7 - 1/2" x 4FT Rebar in the center of the slab. I just scraped the blisters on the surface and the slab certainly looks and feels solid. Is there anything else you suggest that I do? The boiler is probably not arriving for another two days, so it will have been approximately a week of curing. Thanks!

I think it will be OK then. I'm glad you reinforced it. The longer you can wait the better. Cheers.
