[Shop-talk] Pervious landing for deck stringers?

[Thomas Coradeschi]

Jim: I would not have the stringers land on anything that is not solid, regardless of what’s underneath. I’d suggest (depending on what the stringers are made from) a pressure treated 2x10 or 2x12 at a minimum.

I'm thinking the constant boucing of the stringers would slowly bore holes into the stone dust and change the level of the stairs. Am I overthinking it? It's an 8' wide staircase with 7 stringers, so the PSI is very low, as is the frequency of more than one person at a time using the stairs.
