*I just realized that this should have probably been posted in the FOUNDATION forum* I have a crawl space that is about 18-24" high. A couple of the girder supports have rusted where they meet the concrete footing due to an old standing water problem. I have fixed the water problem (via french drain) so the space is complete dry now. I'm looking for some suggestions on how best to replace these rusted supports. Currently they are adjustable metal posts that are embedded in the concrete. My two ideas are: *preferred method* 1) Cut off the old post where it meets the concrete pad and remove it completely. Put in a Simpson Strong Tie adjustable pier post (EPB44PHDG) This should slide into the embedded metal post (with just enough room) and the washer and nut would rest on the concrete footing. I would then use a pressure treated 4x6 to support the girder. This would allow me to adjust the post over time should the need arise. Would this work and be up to code in California? And, am I allowed to use a 4x6 post on a 4x4 pier support? *Alternate method* 2) Cut off the old post where it meets the concrete footing. Insert a PST 4x6 and use Simpson Strong Tie 'A' brackets to anchor the 4x6 to the concrete footing. Then use a different type of bracket to attach the post to the girder. This would require drilling new holes into the concrete footing for the anchors and since space is limited, I'd like to try and avoid this if possible.
