What’s the best adhesive to bond concrete block down to a concrete floor?
In the garage I’m building, I need to build up a post between the roll-up garage door and the walk-in door on the gable end.
There is a steel beam header across the top of the opening, so I just need to frame in for the 2 doors. Slab on top of 4′ frost wall.
Between the 2 doors, I’ll need to build up a post. Was planning on cutting a 3-1/2″ thick concrete block to a roughly 7×7 square, gluing that to the floor, and building up from that, starting with a piece of PT.
That way, if there’s any standing water around the base, it’s not wood in the puddle.
I’m thinking that I could get away with scuffing up the floor, and using PL Premium to glue the block down. Is there another adhesive that would work better? Should I use a separate caulk/sealer around the joint?
Had thought originally about drilling & pinning the two together, but if I have a good adhesive, I don’t think it’ll be moving unless I (or DW) back into it with a vehicle.
Thanx

Don,
There exists a real possibility that someone will bump your post with a car, given where it will be located. I'd glue it and pin it with the same all-thread that holds down the sill plate.
PL Premium works wonders, but the product reputed to be the strongest is called "Concresive." Master Builders has it, here: http://www.guaranteedsupply.com/products-MasterBuilders.htm

Thanks for the link.
As for bumping it, I've been trying to decide whether I'd want it more solid or less:
Since the post isn't needed to hold anything up (steel H beam header spanning both doors, my thought is that if the post gets hit, maybe I'd want it to fail rather than having it transfer the hit up to the rest of the building.
I had been thinking it would be kind of a pain to line up holes in the floor and block, then Hilti nail the sill on, but I guess it would be pretty easy to just drill down through everything and epoxy a piece or two of allthread through the whole mess.

What costs more to fix? The car or the facade of the building? I'd go with the "breakaway" post. ;-)
