I am having some repairs made to my 15 year old pole barn, used for horses. Among other things, much of the dirt around the barn has blown and/or washed away, exposing footings and leaving openings under the walls in places .

The contractor had 2 ideas for replacing the dirt, using either 1-1.5" gravel or using screenings. I'm concerned about the horses walking on the gravel and wonder if screenings near the doors to the stalls and gravel elsewhere would be best.

I would be grateful for any input.
