Introduction of Pier and Beam Foundation
Important Point
- The foundation plays important role in the construction of the building. The strength of the structure depends on how the foundation of the building is constructed.
- In the olden days Pier and beam foundation is widely used in the construction of these structures because of its economy.
- In this article, you will get to know about the Pier and Beam Foundation, Advantages and Disadvantages of Pier and Beam foundation.
What Is Pier and Beam Foundation?
The Pier and beam foundation is a large diameter cylindrical column which is constructed to support the superstructure and transfer the total load into the underground strata.
The Pier and beam foundation is also referred to as the footings which are the columns that are constructed to hold this structure. The beams are connected with the piers to transfer the load into the ground. It is a common type of foundation which is widely used for the construction of residential buildings.
A pier and beam foundation which includes the three main elements such as concrete piers that anchor the house foundation to the ground.
The second is the posts or piles that run between the piers and the horizontal beams and the third is the wooden beams that support the weight of the house.

Pier and Beam Foundation Spacing
A true pier and beam foundation consists of pedestals (piers) embedded into the ground and spaced at an average of 5 to 6 feet on center with wood beams supporting the floor joists. Poorly draining properties are more likely to have foundation issues and movement; regardless of the age of the foundation or the home.
Post and Pier Foundation Spacing
While 8 to 10 feet apart is a sufficient distance for foundation piers to support most structures that would sit atop a post and pier foundation, if the building is particularly tall or made of heavier materials such as brick or metal, it’s not uncommon to place the foundation piers even closer together.
What Is Pier and Beam Foundation?
A pier and beam foundation is an alternative to a slab or basement foundation. Slab foundations typically are inexpensive, can be built quickly, and are made from reinforced concrete. In a pier and beam foundation, a concrete pier is reinforced with steel (rebar), forming a strong cage within the pier.
House Leveling Pier and Beam
A Pier & Beam Foundation can be repaired and leveled by installing steel pilings or concrete pilings under key locations under the concrete perimeter beam. The interior is adjusted by adding or removing shims placed on top of the interior pads or columns.

Post and Beam Foundation
A post and pier foundation—also sometimes called a pier and beam foundation—is one of two major types of home foundations. Spanning up from the concrete piers are either concrete or wooden posts, and along the tops of the posts run horizontal wooden beams that provide the bed on which the structure will be built.
How Many Pier Blocks for Shed Foundation?
As with the on-grade foundation with concrete blocks, at least 8 piers plus one in the center will be necessary. Therefore, provide for a minimum of 9 piers. 2 – Use a posthole auger to dig holes 10” to 12” in diameter and approximately 54” deep, depending on the area.
Pier and Beam Foundation Cost Per Square Foot
Generally, you can expect to pay around $9 per square foot to have a pier and beam system installed. This price may be higher depending on where you live in the United States, as pier and beam have become something of a niche request. For an average size home, you will pay between $7,200 and $13,500.

Pier and Beam House
First, a pier is sunk into the ground deep enough so it butts up against stone and a concrete base is added. This helps to ensure the piers won’t shift. Next, beams are extended from one pier to another. These will support the joists and flooring of the home.
Pier and Beam Vs Slab
While pier & beam systems do create very stable foundations and are preferable in some situations, they can deteriorate over time. However, they are usually easier and less expensive to repair than a slab foundation. It’s also easier to install, repair, and add plumbing with this kind of system.
Pier and Grade Beam Foundation
Pier and beam slabs consist of brick, stone or concrete piers and wooden beams that support the weight of the home. Unlike slab foundations which sit directly on the ground, pier and beam foundations are elevated, usually about 24” off of the ground.
Foundation Beam
A grade beam or grade beam footing is a component of a building’s foundation. It consists of a reinforced concrete beam that transmits the load from a bearing wall into spaced foundations such as pile caps or caissons.
Building Piers
Pier, in building construction, vertical loadbearing member, such as an intermediate support for adjacent ends of two bridge spans. In foundations for large buildings, piers are usually cylindrical concrete shafts, cast in prepared holes, but in bridges they take the form of caissons, which are sunk into position.
Shed Foundation Piers
A shed pier foundation consists of 4 or more concrete piers with diameters of 12”-24”, which are poured to a depth at least 6-12” below the local frost line. Ideally, shed piers should be combined with a gravel shed foundation.
Pier Block Shed Foundation
A pier block shed foundation is not strictly a permanent foundation it comprises of a series of concrete blocks laid directly on the ground (occasionally a shallow hole is dug and filled with crushed stone), the tops the blocks are then levelled to support the main floor beams of the shed.
Pier Foundation Design
A pier foundation is a series of vertical pillars or piles that transfer the building load to the soil. Beams are then built on top of these columns. They lift the house off the ground and are very popular in coastal regions where rising tides are a problem.
Can You Build a Shed on Pier Blocks?
We don’t recommend pier blocks for sheds because they do not provide frost-proof structural support and are at risk of shifting over time.

- Ensure that there is sufficient space for equipment and workers to maneuver.
Install Temporary Supports:
- Before starting the leveling process, install temporary supports or jacks to stabilize the affected areas.
- Use hydraulic jacks or screw jacks to lift and support the beams and floor joists, providing temporary stability during the leveling process.
Lift the Foundation:
- Once the temporary supports are in place, carefully lift the foundation in gradual increments.
- Lift each support point slowly and uniformly to avoid causing additional damage to the structure.
- Adjust the jacks or hydraulic systems as needed to achieve a level position.
Secure the Foundation:
- Once the foundation is leveled, secure it in its new position to maintain stability.
- Install permanent shims or wedges between the beams and support posts to provide long-term support and prevent future settling.
Best Pier and Beam Foundation Construction Methods
When it comes to pier and beam foundation construction methods, there are several approaches that can be considered. The choice of method depends on factors such as soil conditions, climate, local building codes, and personal preferences. Here are some commonly used and effective pier and beam foundation construction methods:
Concrete Piers with Wooden Beams:
- This is a traditional and widely used method for constructing pier and beam foundations.
- Concrete piers are poured into pre-dug holes, typically reinforced with steel rebar for added strength.
- Wooden beams are placed on top of the piers, providing support for the structure above.
- The beams are leveled and secured to the piers, creating a stable foundation.
Steel Piers with Steel or Concrete Beams:
- Steel piers offer increased load-bearing capacity and can be a suitable option for areas with expansive or unstable soils.
- Steel piers are driven deep into the ground until they reach stable soil layers or bedrock.
- Steel or concrete beams are then placed on top of the steel piers, providing support for the structure.
- The beams are leveled and secured to the piers, creating a durable and stable foundation.
Pier Beam Foundation
Pier and beam foundations, also known as post and beam foundations, are a type of foundation system commonly used in residential and light commercial construction. They consist of a series of vertical piers or columns that support horizontal beams, which in turn support the structure above.
