In order to get privacy in our backyard weíve build a large berm(mound) about 8 feet high. I did put in steps out of natural stones to allow easy access to the top. However, here in Southwest Florida due to the sandy soil and the summer rainy-season the stones donít stay fixed. It needs a constant rework. (see picture)
Iím looking for an idea to get a durable staircase solution. The angle to the bermís top is about 15 degrees.
