My wife and I have purchased a 102 year old Craftsman home (3,500 sqft) and our basement has some challenges. Some we are working on just fine (heat & A/C duct not screwed together & hung wing wire), plumbing etc. But others such as two areas with existing supports - steal screw piers/jacks (finished basment); and unfinished basement for minor joist are supported with a 2x4 sitting on rock(s).
The steel screw jack / piers are sitting right on the floor rusting away. I want to replace, so a system like Ellis 4x4 screw jack sitting on a pier (concrete) pad or just some kind of concrete column? The unfinished basement, the same kind of quetion. So what are good solutions? What are you doing? Next, keeping wather out of a 102 year old basement?
