I’m doing some foundation work on a pier n beam house and the main beam is gonna be replaced so I am lifting up the floor joist and placing them on temporary supports so that way there’s no weight on that beam and I can swap it out

however,

I am finding some of these joists Are no good anymore so when I’m jacking up the floor joist to place on the temporary pier. Some joists start to crumble and collapse on me Typically with good wood. I have my bottle jack and I just place a 6 inch block of 2 x 4 in between the bottle jack and the joist that I’m jacking on just to give it that protection so the jacks not going into the actual wood and spread the weight a little bit.

That’s not really working in this scenario what do you guys find? What do y’all do in this kind of situation, I mean, I guess I can just get a longer piece of wood to spread the load from the bottle. Jack on the joist that I’m trying to jack up.

Any advice?
