Dirt erosion underneath concrete front steps, fill with gravel?
We have poured concrete front steps that lead into our house from the ground level, and I've always noticed how there's dirt missing underneath them, but finally getting around to addressing the issue. The home was built in '85, and fortunately the stairs haven't sunk yet *knock on wood*, but I'm wondering what can be done to prevent the erosion from getting any worse, and possibly filling in the void created by some soil erosion.
I wouldn't classify the erosion as terrible (to my untrained eyes), but I'll post up a picture later. The house has proper drainage with gutters working properly and long black tubes to carry the water away from the house. However, I would like to do what's best to try and fill in the void underneath part of the concrete steps, to avoid them sinking down the road.
Can I buy bags of a certain kind of gravel and fill in underneath the steps vs. just dirt? Any advice is greatly appreciated. There could've been a problem w/ water drainage at some point that caused the erosion (I just bought the house a year ago), but drainage definitely isn't a problem now.
