DIY Patio - any red flags with the job so far that I need to correct before pour?
DIY homeowner here, wanted to replace my old, busted-up paver patio with a slightly larger slab. Looking for some opinions on how my forms/prep look, and anything else I might be forgetting. See below for a list of things I know I still need to do. Approx 12'x18' and aiming for 4" slab @ 4000psi, might be slightly thicker in some spots. Went with #4 rebar on roughly 18" oc (ended up being closer to 17", although the one side ended up with a slightly bigger gap). I know #4 rebar might be a bit overkill for a patio slab, but I wanted to have the option to throw a hot tub on it in the future. I'm also in Wisconsin, zone 4b/5a, so we can see some pretty bad winters. Tings I know I still need to do: But the rebar up on chairs - I'm thinking I need 1.5" so it sits in the bottom half of the slab? Backfill in around the forms to prevent leakage Attach the expansion joint to the house (construction adhesive + tapcons) Buzz off the tops of the stakes Questions I still have: What is going to be the best way to go about screeding this? I could go perpendicular to the house, but I'm not sure how well that work would because there isn't a form to rest the screed on at the house. I could go parallel to the house, but then would I need to put a temporary form down the middle, as the screed wouldn't reach all the way across? How high should I raise the rebar? Most of what I've heard online is aim for the bottom half of the slab - so 1.5" chairs. However, I see other people say go in the top half if you live somewhere with cold winters. Control joints - what do I need? Thinking a 6' grid? PS. I will have plenty of hands on deck for pour day, including somebody who has some concrete experience. So I'm not going at this totally green. https://preview.redd.it/28tfv9ra5u2f1.png?width=640&format=png&auto=webp&s=346f7a4d91d5658ba947060cd84c52f98155442c https://preview.redd.it/xju5lz5b5u2f1.png?width=640&format=png&auto=webp&s=b51cdb13080160eee5aa6da1050b87f536b55b55 submitted by /u/Wzup [link] [comments]
