FOAM TO USE AS AN ALTERNATIVE TO NON - SHRINK GROUT
FOAM TO USE AS AN ALTERNATIVE TO NON - SHRINK GROUT
(OP)
Is it okay to use foam as an alternative filler to non - shrink grout on gaps between the steel column and its base?
Thank you, Hoping to hear your good comments and suggestions.

Maybe it is very light grout. And they shook it, rather than mixing with a trowel or hoe?

Had a job where I called for a 90-deg hooked rebar at the base of a retaining wall and the "contractor" replaced it with 2-straight bars cut to the length of the hook (they didn't have a bender). I imagine these guys didn't have grout?

In theory you can support a good amount of load on anchor bolts alone. Given the position of the bolts within the flanges, I'd say that was not the intent of the designer. If this is supporting a roof or floor, it likely needs (real) grout.

Before freaking out on this, I would determine if the spray foam was used to provide a grout dam. A very common trick in concrete form construction.

Here's to hoping that's what they did but it looks to me that the foam is squirting out from under the plate...

TME - We do that often - covers a multitude of sins in form construction. Spray it into small gaps in the formwork, let it harden, then shave it flush with a knife. Great at the bottom of wall forms on footings that are less than perfectly level & smooth. Very helpful when you're using SCC, as SCC will find every hole.
