Re: Footing Steps

[Subject Prev][Subject Next][Thread Prev][Thread Next]
If I can't step to a 2' by 4' run then I run into the next wall, call for
good compaction and design the connection and footing capacity for a
suitable span from the foundation I butt into.  Usually allow for at least
6' or more.

In residential here, if you are not careful, the contractors will just run
down the hill.  For slopes steeper than about 5% or so I review the
conditions for stability etc and may sometimes require upgrade to the
footings or create load collection to other parts of the foundation
