Real rr ties and pt 6x6 walls is all we did in the late seventies and 80s some are still around. You can expect a properly built 6x6 pt wall and steps to last min 20 years. With the occasional tie hear and their degrading prematurely.
Synthetic 8x8 and soon stone look slabs will be the future. I've used old granite curb stones and PT but never RR for treads. They are rough and you will track the pitch everywhere. Plus I rarely find ones that aren't warped, twisted or filled with spike holes. Posted via Mobile Device
