Rotten Rim Joists at Your Concrete Porch?! Here's Why It's Happening.

Ғылым және технология

When constructing a concrete porch, it should never be poured against wood framing or directly against the weather resistive barrier, as moisture can be easily wicked from the slab to the framing components without a drained capillary break, resulting rotten rim joists and deterioration of your wood framing. In this video, we're talking about how this detail has led to a ton of rot problems in thousands of homes and what you can do to prevent it from happening, as well as how to address existing conditions.

    Good stuff man. I always have to shake my head a little when I see this very unnecessary type of damage especially when it's the result of "professional" design.

    Thank you! Raising awareness about the implications of these details is crucial.

    The amount of issues I see in crawlspaces due to concrete porches poured up against the house is staggering. Great video! Would love to see you do a video on ICF

    Thank you. My concrete porch is a huge thermal hemorrhage. It's against a brick crawl space. Even with mineral wool you can still feel the heat and cold off the porch.

    Fantastic! Building using the “humanize” principles. Building homes that last for generations. Thanks for sharing.

    Neat, I wouldn't have even thought this was allowed for all the reasons you mentioned here. If you feel like answering, while most of this isn't applicable indoors, are there concerns for doing this internally? IE: The same detail, but for a house slab (fully insulated and vapor barriered) meeting the rim joist of an i-joist floor flush with solid plastic vapor barrier between them?

    Good stuff here. Thanks. My son and I are currently building two houses and a studio on 20 acres where we will have a small homestead/farm with our families. We are doing pretty much everything less the concrete work and gutters. This subject has been on my mind. I have been and electrical state contractor in SC and prior as an electronics engineer. Its sad some of the things people do wrong that could have taken little effort to get it right. I overkill pretty much everything ha ha. I want these houses to be here for my grandkids and beyond should they choose to live here. Thanks for all your efforts. My son and I run a KZread channel ourselves following the homestead. We started with a forest so lots of work just cutting and clearing trees. I am considering putting insulation over top my roof. I want a clean dry area in the attic. I will check your channel for info on that subject. I put a slab with Stego underlayment in the crawl space to keep it dry. No bugs and rodents will be inhabiting my space lol. Thanks again! Terry

    I would have used Pordrän or Isodrän, but you dont have that.

    I like the idea of a capillary break. The last detail you show seems to have the slab resting on the backfill. This structurally isn’t a good idea as settling will occur. Especially if you have 9 and 10 ft poured walls. I do agree that this is a major issue and problem area with moisture.
