Ive tried to search the threads and really havnt' been able to find any answers or opinions so I'm posting this question. Why is it necessary / recommended to build steps as a solid unit vs using compacted base CR6? We did a job a while back with 2 steps to a landing. We used crusher run compacted every 2 inches from the ground up. There hasnt been any signs of settling as of yet. Just wondering, if It can be expected to over the next few years or not. Just seems to be rather cost effective to use compacted base material vs stones.
