Bricking up door/damp
If you are going to remove the door and simply replace it with blocks, I would urge you to finish the outside like the existing walls are. Perhaps that is your plan all along but you did not specify that you were.
As mentioned in a comment, the floor slab that the door sets on needs to be broke back to the point that the face brick on the outside can pass in front of the slab. The existing brick need to be &quot;toothed out&quot; or raked back, since there are so few courses that the waterproofing layer (WPL) can be tied into with new material. The stucco needs to be carefully cut back too, or should be so the blockwork that serves as backing for the stucco can tied in to and expose the edges of the existing WPL to tie into that as well.
Then of course, lay up new brick that matches the original with the same mortar color and the necessary coats of stucco to build up and finish that the same to match existing as well.
