new block to existing poured wall ??????

This is a copied and extended questrion from my previous unanswed posting....please help!

when adding blockwork to an existing wall, should this joint be gap filled with joint movement controll sealant?

Should it be mortared?
Should new footings be tied (rebar rods) to existing footings?

There is not enough information to answer it correctly.

I am adding an addition to my house. The existing basement is poured wall with a wood stud 96" wide walk-out opening.

I will be installing new footings, and new block to create an addtition. The existing walout opening will be filled with new block and a door into the addition basement area.

I trying to determine if I can block right from the existing walkout opening into the new basement addition area without a flexible joint.

does this info help?
can you tell me what other info will help you answer my question?

thanks

At least in Florida, code requires you to marry the two footers.

For example, we were required to do the following:

Use #5 rebar
Drill a hole a minimum of 6" into the existing footer at 3" above the rebar in the chairs of the new footer .
Fill the hole with epoxy and insert a piece of rebar to end approx. 3" from the far edge of the new footer.
Had to be done every 6' for us since we were pouring a mono slab to the side of the house.

Can't help above ground
