There are two base types of pier & beam foundations. Those with a concrete grade beam around the perimeter and those without.
With a Concrete Perimeter Beam
If a home has a concrete grade beam, the perimeter can be lifted using pressed pilings (steel or concrete).
Adjusting Interior Floor Levels
The floors of a pier & beam house sit on beams (typically 6 in X 6in). The beams are supported by “piers”. These “piers” are typically either poured concrete piers, Bois d’Arc stumps, or pre-made concrete blocks.
The floor levels can be adjusted by raising the beam off its support and adding or removing steel shims. Sometimes supports (piers) need to be added or changed out if they have failed.
On a pier & beam foundation, it is often necessary to replace wood in the crawl space located under the floor. The wood may be cracked or damaged due to moisture and/or insects.
In a pier & beam foundation, adequate ventilation in the crawl space is required to minimize rotten wood and mold or fungus growth. Vents and/or mechanical ventilation systems can be added to reduce moisture build-up and stabilize humidity levels in the crawl space.
