I have a home that recently flooded and want to fix the flooding potential by turning a walk out door into a window. I have a poured foundation wall that I would like to infill bottom half of door opening with concrete and rebar. The question is.. will the concrete infill, with rebar tying into existing foundation, hold up to pressure of backfilling with soil? Whats going to happen when ground freezes in winter time? I live in Fargo ND.
See attached drawing
Thanks in advance!
