We are adding an addition on the back of the house. The old exterior footing will now essentially support an interior wall with the old exterior side now being under roof and concrete slab.

In backfilling against this concrete footer and 3 block masonry wall, does it matter whether the back fill is packed with rock or dirt as it runs under the new concrete slab?

Dirt is only good for growing things in, not for constuction.

Use compacted granual soil for strength and stability.
