Attaching Concrete Block to Floor

[brycez28]

Not really sure where this post best fits, but here it is. I have a concrerete slab for my sunroom. I'm remodeling it and turning it into an all seasons room. Around the entire outside parimeter of the room, there is a layer of block (I'd guess 4" thick, 8" tall, 12" wide) that has 2"x4" framing attached to it. On my south wall (about 10' long), I'm replacing the screen door and small window with a sliding patio door. When removing the door and window, I discovered that the block is no longer attached to the floor and the wall/roof is holding it up (I can push the wall and the bottom moves). I'd say there is around 1/8" - 3/16" gap between the bottom of the block and the floor. A lot of the block will be removed with the framing/installation for the patio door, but how would I go about resecuring the block to the floor and seal out the elements? To the left of the patio door space, I can access the block on both sides. On the right side of the patio door space, I can only access the block on the outside because of stairs going up into the house being against the wall on the inside.

not sure how accessible the blocks are, can you drill into floor in the core , install a pc of rebar and fill with concrete?

If it were mine I'd build a temporary support to hold the weight and rip out all the lose block. I'd then install treated wood and drill and insert threaded rod. I'd then build a short wall to fill in the gap. Tie the two walls together with threaded rod and bolts.

An alternative, jack it up and insert new blocks and drill down and install threaded rod or rebar.

This isn't for casual diy type guy when you start ripping sills out of a load bearing wall.

Your best bet is to remove the existing and lay something more robust, like 6" block, in it's place. Van Der Vart might also make 4" bond beam block, which could work as well, as long as you take you time in setting them plumb, and fill the void......

Taking the block out and reframing is more my skill-set if there isn't an easy way to fix the block that is already there. As part of the remodel, the current siding and sheeting is coming off, along with the pine boards that finish the interior (will be drywalling).

Here are a couple pictures for a better idea of what I have.
