    Lift install: Is residential concrete slab typically thinner by footer?

    I'm not aware of any company that will deny warranty with a name brand anchor. It'd be tossed out in court (after an engineer testifies) and they'd be responsible for all incurred costs. The supplied anchors are usually lower grade than what you can get in a consumer hardware store, and far...

    Lift install: Is residential concrete slab typically thinner by footer?

    OK, for anybody else struggling with this I'll break down what I learned and figured out. The problem with drilling holes close to the FOOTER (confirmed with a concrete guy, that is the correct terminology) is that those particular anchors will be in tension in weak concrete. Yes. As my...

    Lift install: Is residential concrete slab typically thinner by footer?

    Dude...I was trying to be nice. I got everything figured out while you were pontificating - the manual was garbage and didn't address anything you claim it does. I guess the difference between 30 posts in 11 years vs three thousand in 9 years is getting **** done vs flapping your gums about...

    Lift install: Is residential concrete slab typically thinner by footer?

    Atlas recommends 6" from any concrete edge...trying to determine if I need to measure that 6" from footer/stem plane or the actual edge of the concrete (which is hidden). Honestly I worked underneath a janky maxjax installed 1" from a stem wall (could actually see the edge in my old garage) for...

    Lift install: Is residential concrete slab typically thinner by footer?

    Seriously been on this board for over a decade - didn't know it had turned to a bit of a cesspool like the rest of the internet. Somebody posts an honest question and is 100% up front that they don't know about a subject (concrete) and does their best to describe the situation including taking...

    Lift install: Is residential concrete slab typically thinner by footer?

    Quite possibly - I ASSumed the stem wall was directly supported by the footer underneath based on every diagram I've seen on how this garage would have been built. If that is not true then I may have used the wrong word? Again I have zero concrete experience other than seeing a few poured...

    Lift install: Is residential concrete slab typically thinner by footer?

    I appreciate the input and ideas. What you described is how I did the last ones, but did not use a glove to coat all the threads. I'll try that next time. Regarding your swinging robot arms - not to piss on your logic - but I think engineers like myself have more to do with which anchor to...

    Lift install: Is residential concrete slab typically thinner by footer?

    I've only tried epoxying the studs once (on a repair of my old maxjax) and it didn't seem to make a difference. It appeared that the stud was such a tight fit that as I hammered it in the epoxy just squished up and out the sides. I wasn't comfortable over sizing the holes just to fit epoxy, I...

    Lift install: Is residential concrete slab typically thinner by footer?

    Thank you sir! I'll follow your advice. Any recommendations on exactly how to check and what size hole necessary? If not I assume use my smallest SDS max drill bit and use a flat head screw driver as a feeler to see where I hit paydirt.... Sorry I'm overly cautious after having drilled holes...

    Where to put the mini-split

    You're right about most of that....but technically its to dry your clothes in asia...but we americans try to use it for dehu. It kinda works if you setup a proper controls system lol Sorry couldn't help myself, former mitsu ductless engineer here ;)

    Lift install: Is residential concrete slab typically thinner by footer?

    Thanks, very helpful information. If I had to guess from the way it looks its a "floating slab"... Trying to quickly learn some terms here - I googled "monolithic slab" and don't THINK that is what I have, but honestly don't know whats under the grade without digging down outside? Obviously I...

    Lift install: Is residential concrete slab typically thinner by footer?

    I am in the middle of a 9k lift install in my vintage 1987 "higher end" garage. I spoke to contractors in town and they tell me this vintage/area of construction with this builder usually had minimum 4" consistent pours, so in general I'm very comfortable setting my anchors (this is my 4th time...

    MaxJax Transport, Install, Impression, and Comparison

    They quoted me $135 for a liftgate service. I'm pretty annoyed, the closest terminal is 90 miles away :/
