When they do inspect the framing, I would imagine if something stood out as clearly wrong they would notice it. Based on the answer by isherwood that it's likely fine structurally, I will just do some cosmetic work and I think I'll be in good shape. | |

| Jun 14, 2023 at 12:24 | comment | added | HelpinKC | @crip659 I do have weather where rain can freeze. I was thinking of using a water blocking product to fill the gaps above grade to help prevent this. Something like: quikrete.com/productlines/hydraulicwaterstopcement.asp | |
| Jun 14, 2023 at 12:22 | comment | added | HelpinKC | @FreshCodemonger I bought MasterCraft 5000 PSI Concrete Mix. I read the instructions again, and they indicate to use approximately 4.5L of water per bag. It also says use water as needed--but perhaps it meant add the 4.5L as needed over time to achieve consistency. Many other products have a range of water to use. I'll aim to be precise the next pier and see what I get. | |

| Jun 14, 2023 at 3:15 | comment | added | HelpinKC | I will aim to mix for a longer amount of time on the next pier. It's 36 inches deep. | |
| Jun 14, 2023 at 3:15 | comment | added | HelpinKC | @JACK I mixed it by hand. The directions said to start with 4 pints and work your way up from there as needed--no specific amount given. | |

In other words, the specified amount of water should have been sufficient for the whole bag. You had overly wet clumps (weaker than spec) and probably normal clumps. If the pier is fairly tall, you might take a chance; if it was only, like, a foot deep, I'd bust it apart (rotohammer/chipper). | |
