Old rotten locust post
This was one of the posts that was failing
Failed Support
As you can see, moisture and decay lead to the post failing.
Flir Moisture Meter
High amounts of moisture were present in the basement.
Failing Rolled Steel Post
The moisture is why this post was failing
New Footer Pocket
The floor was not thick enough to be load bearing, so new large footers were installed.
Temp Supports
These supports allowed for the removal of the failed support posts.
New Steel, Waterproofing and Posts
The new supports were far superior to the old.
Steel
Notice the steel under the sagging beam which was used to lift and level the beam and ensure it stayed in the appropriate elevation.
