FOUNDATION / FOOTING UNDERCUT
/ SETTLED / LIFTED / TILTING:
The inspector notes a condition which indicates
either excessive movement of the foundation or
the potential for damage to occur to the
foundation should the condition not be remedied.
Some causes are: fill settlement, "downhill
creep", tree root lift, animals digging
under the footing, "basement"
excavations by the homeowner, erosion, excessive
moisture around the building, earth tremors,
etc. The inspector will usually indicate the
severity of the condition if it is visible.
Often the problem will be minor and typical for
the age of the structure. This situation may
require the assistance of a Concrete Contractor.
It may be necessary to pour or pump concrete
under the footing to stabilize it. Adding dirt
under the footing usually will not be sufficient
since it will simply settle away from the
underside of the footing. It may be necessary to
jack the foundation up and add concrete
underneath. It is commonplace to leave the jack
in position and pour the concrete around the
jack. Special foundation jacks are available for
that purpose. Sometimes it will be possible to
pour a new foundation under the building behind
the affected section. The new foundation
relieves the affected section of its load. More
severe settlement or other movement, where the
foundation has shifted or where differential
movement is noted may be due to earth settlement
or movement. You are advised to consult with a
Geotechnical Engineer if settlement-caused
foundation or slab cracks are noted.
