Hello guys, I am working on the foundation inspection course and under-pinning was mentioned as far as a foundation wall reinforcement fix. Please let me know what under-pinning is?
" In construction or renovation, underpinning is the process of strengthening the foundation of an existing building or other structure. Underpinning may be necessary for a variety of reasons: The original foundation isn’t strong or stable enough. The usage of the structure has changed."
From: https://en.wikipedia.org/wiki/Underpinning
One method of underpinning: 1:14 sec.
Thanks Larry, I can see under-pinning would be a costly endeavor!
