Pier and Beam foundation
Pier and beam foundation is a foundation that has a crawl space between the ground and the structure. The pair and beam foundation is also referred to as post and beam foundation. Crawl space below footings and living space to support foundation are present in pier and beam foundation due to this it is more stable in shifting soils.
The exterior wall of the home is supported by a masonry foundation with the help of pier and beam construction. With having a pier and beam foundation there are pros and cons because there is a crawl space beneath the house.
For things like plumbing repairs or re-writing without having to break through a section of a slab, this can access that area more easily. Pier and beam foundation has an over slab foundation this is an advantage.
The construction of the pier and beam foundation is constructed with three primary components. The first one is deep in the ground reinforced concrete footing is buried which ensures the entire foundation of building in the ground to prevent shifting in volatile soil. Next, the pier is constructed and attached to the footing and piers are made from brick or concrete. The pier comes out of the ground and supports the beam which is connected to the floor joists.
Installation Of Pier And Beam Foundation:
There are several steps in installing or applying of pier & beam foundation which are given below;
Step 1: Dig Holes & Pour In Gravel & tamp
First, you must dig holes into the ground. Once those holes have been drilled, before placing pre-formed cardboard forms on top of it gravel is poured and compacted into the bottom.
Step 2: Place Tube In Holes & Begin Filling
Before being filled to the top with concrete, the forms are leveled with the ground and each other. Metal hardware that will be bolted to the floor support beams is placed into the top of the forms before concrete cures.
Step 3: Place Footing Hardware in Forms
Allow the concrete to fully cure and mound skids in hardware. When the concrete cures and wooden beams are bolted in and the floor is built on top of them.
Step 4: Attach Subfloor to Skids
Piers are spaced evenly otherwise the beams will begin sag which in turn will cause the windows and doors to stick. Also, you must make sure that there are no air bubbles in the concrete.
Use a spare piece of rebar and repeatedly stab the concrete all to the bottom of the form making sure to get along the walls of the tube after the forms have been filled halfway.
Performance Of Pier And Beam Foundation:
The performance of this foundation depends on two factors:
- First is the structural integrity of wood pier and due to the moisture for much longer of time naturally preserved wood that is able to resist the decay. The common practice is to use the cedar posts for piers.
- The second factor of performance is drainage, the well and maintained drainage system can improve the performance of a pier and beam foundation.

For all pairing methods of foundation repair uses ECP steel piers.
ECP helical piers are installed into the ground and then the load is tested after this the total weight of the structure is lifted onto the piers and stabilize the structure.
It is most important to have an experienced foundation repair contractor if you see any foundation problem and offers you the foundation repair that you may need.
Advantages of Helical Piers:
- No vibration
- Can be installed in any weather conditions
- Load transfer after installation
- To verify the capacity load test is easy.
Advantages Of Pier And Beam Foundation:
There are many advantages of pier and beam foundation:
- Termite control
- Accessibility and ease
- Easy and economical repair and change of foundation
- On land with slopes, pier and beam foundation can be created
- Easily access to pipes and wires
- Builders need less equipment and space for installation.
Disadvantages Of Pier And Beam Foundation:
- Development of moisture
- Flooring can be difficult
- If crawl space is too low difficulty in getting under the foundation.
