Pier & Beam
Pier & Beam foundations are made of three main components.
- A concrete foundation covers the perimeter of the house.
- Concrete columns are installed inside of the perimeter of the foundation.
- Wood beams are placed on the interior concrete columns and on the perimeter of the foundation.
As Pier & Beam foundations are more costly to construct than slab foundations,
pier & beam foundations are often used for custom-built homes or for special situations where homes need to be elevated off the ground (such as homes built on a flood plain).
A slab foundation is made mostly of reinforced concrete. It is a thick slab of concrete that is poured directly over the ground where the house will sit.
Standard slab foundations are usually around 6″ thick.
To accommodate for additional weight around the perimeter of the home, the perimeter of the slabs are typically up to 36” deep. The deepest part of the slab foundation is called a beam.
To reinforce the center section of a slab, beams crisscross the middle in a waffle pattern. Interior beams are often 12 feet apart from each other.
Slab foundations are almost always enforced with tension cables or steel rebar rods.

How We Can Help Preserve Your Building
We offer soil stabilization piers. We offer two types of piers on slab homes which are concrete press pilings and steel piers. Both piers are installed by digging under your slab. The slab of your home is only 6 inches. Concrete beams give the home support. Most beams are 2 feet deep and 1 foot thick on the outside perimeter of your home. The beams are 12 to 14 feet apart throughout the center. The beam is where we place the piers to raise and support the home. Piers are installed approximately 6 feet apart depending on how unleveled the house is.
To build a concrete piers, you dig three feet beneath the concrete beam, 2-foot-wide, and 1 foot back under the concrete perimeter beam. We use a hydraulic compression machine to press the precast concrete piers (6 inches by 1 foot). We continue to press the piers into the ground to the point of refusal (until they raise the house). Again, it depends on the soil to see how far the piers go. Most piers go approximately 9-11 feet.
