I have a older house to fix up. And there are some steel pipes, pieces of trees logs, and old Adjustable Steel Building Columns that need to be replaced.



My question is how do I figure out which ones are right for me, I want to make sure that the weight is being held up correctly



other notes -
1 brick column
2 wood tree logs
3 pieces of old metal pipe (2 times thicker then the common adjustable column for a regular house.)
4 adjustable newer jack posts (maybe 30 years old), best guess 18,000 to 11,000 range.



All the columns are rusting or rotting. you can see where some of the rust has dropped through. The house is a 2 two story house 1800's, looks like there is slate put on top of roofing martial. The has had 2 layers slate/shingles for at least 50 years.


Thank you

Ayuh,..... If you put concrete pads under the columns, they shouldn't rust,......

My local precast concrete place sells what they call Camp Pads, which are reinforced concrete, 6" thick, in a 2' circle,.....
Good thing they're round, so they can be rolled into place,.....

'bout any of the available Lally Columns should be plenty stout enough for the loads yer lookin' at,.....
If you don't think so, add more columns to spread the load,....

Image 1 is adjustable lolly column, 3" diameter, from homedepot. Website says this is good for 12,400 lbs. Image 2 shows my rusted out, cement filled original, 4" dia. Photo arrangement is temp only. I will be removing the old column and permanently install the new. How do I know if new 3" is good enough?

I am guessing. Only other way is paying for an engineer to do the support analysis. I think I can guess because the old column is a mid support for 1920's 8x8 beam, about 12' long. It has 16" oc 2x8 floor joists attached to it. On the other side of the floor joists, also 8x8 beam, has no such mid supoort.:smile: I'm not sure why the photo column was installed but I'm doing it monkey see monkey do, only with adjustable column because I don't think another cement filled column is necessary. I do have some experience. If you're not sure, you can use 2. Kind of over-engineer it. I may do that as well. The foundation underneath will be wide enough.

thank you. I found ones that will will support 20,000 at the local store. And my old ones did not have any cement in them. Actually found one of the old boxes looks like the old ones only supported up 11,000 ish.

thats a really good idea thank you The reason why they were rusted out is because the prevoius owners had a gutter pipe that was draining right near the foundation of the basement so it would rain the basement would flood. Now the pipe is fixed its so much dryer.
