Trench Wall Foundation
Signs:
Room addition or enclosed porch settling
Cause:
Structure built on deck or concrete patio with no foundation frost wall.
REPAIR
Excavate outside the effected area to 42 inches below grade. Shore and raise to a compromise level. Install reinforcing
steel (rebar), form and pour a concrete frost foundation.
The Dave Pate Advantage:
The repair is engineered and inspected by the local building department. It becomes more cost effective to install a frost foundation under the existing structure than to demolish and rebuild.
