Attaching footing to retaining wall?
Due to a miscommunication, a concrete retaining wall was poured without any footing. The wall is 4'H x 65'L x 8"W with #4 rebar. The site is pure sand, in a area that was previously sand dunes by the ocean. The proposed fix is to add a footer that will be 18"W x 12"H along the entire width of the inner wall, drilling 6" holes into the wall 3" from the bottom spaced 12" apart and using epoxy to secure #4 right angle rebar to connect the wall to the footing.
Will this be sufficient? My primary concern is mechanical failure due to the rebar not being tied in. Is there another solution you can think of, short of a total re-do?
