I have a foundation of block wall. To get it to the correct height I need to put 4" solid block top cap on it and my sill plate on top of the 4" solid top cap. I can fill in the voids in the block wall where I'm going to need to bolt it down with cement.
My question is how best to secure the walls. If I bury a J bolt in there I'll have to drill a hole through the 4" solid top course that won't be serving any purpose for securing the walls so it's just a bolt going through a hole. I can't even seem to find a bolt long enough that would bury the J bolt in the cement under the 4" solid block in the cement filled blocked wall more than a few inches.
I'm thinking I'd fill in the block wall with cement where I need to anchor the walls and then go in from the top and put in a 1/2" x 6" tapcon (or longer if I can find it like 10") or something so that it uses the 4" solid block and a bit of the cement underneath for grip. Can't tell if this meets code or is even a good idea though.
