looks like the bags are loaded in the top and fed into the hopper.

About 26ft up in the air. Company didn't want scaffolding. 8 " slab with 12" beams and a 4'×4' opening. Did lay out and built. Did not do the rebar. Slab just sitting on about 4" of wall all the way around. Engineer wanted it to be "removable". Was not nervous at all when it was being poured.

Normally we use pump and backpack sprayers for smaller jobs, but sometimes slab is out of reach for them. I was thinking about buying petrol engine sprayer from Stihl, but I'm not convinced about their reach with fine midst. What are your thoughts on that?

Found this beautiful slab in the wild yesterday.

Ever pumped concrete in the clouds about 1,000 ft up

Company that allows butchers to run jobs?

Hired some rebar installers in Winnipeg. They did a fantastic job! Just wanted to give a shoutout to Justlee Construction Ltd. They were super fast compared to our guys. Do yourself a favour and hire rebar installers (Rodbusters) and save yourself more time to do what you’re good at!

Starting to get really use to not having anyone around and doing everything with the couple homies I have. We do about 100 yards a week I just don’t post.

I started making some miniature low-poly concrete models as decor pieces for my friends. I’m relatively new to working with concrete and was wondering if I can skip applying a sealer given that they will be kept indoors?

Please take a look at the WikiFAQ posted here: https://old.reddit.com/r/Concrete/wiki/index

The chances that your situation is covered in the WikiFAQ are pretty dang good.

If your issue is NOT covered in the WikiFAQ, this is the place to ask if that hairline crack warrants a full tear-out and if the quote for $10k on 35 SF of sidewalk is a reasonable price.

Sometimes good enough just is

I’ve been doing one sided walls basically the same way forever, it’s that, some banding wetset into the footing and a stud nailed across the bottom. Anyone have any tricks or anything they do different?

Apologies if there isn’t enough info or this is the right place to ask this. I have no experience in concrete or construction. This is the 2nd floor of a concrete parking garage for my work. It’s always had a little bit of bowing (about a year or so that I’ve seen) but today I noticed it almost looks to be sagging more. I could be wrong but my gut says it shouldn’t sag like that at all. The photo doesn’t do it justice, either. I’d guess the low points and high points are about 8-10 inches apart in height. Thoughts?
