I have some stone stairs that go along the side of a slope that is about 35 degrees. The slope continues to slump causing our stairs to slump sideways. How can I repair these stairs? Is there any way to prevent them from slumping too much? I though of driving some rebar into the slope and angling the srairs a bit into the slope but i am not sure if that would work. Any suggestions? I have attached a couple photos so you can get a better idea of what I am talking about...well, I tried anyway, but this website wouldn't accept my jpeg.
