How Pier Installation Works

Piers can stabilize and even raise homes with slab foundations. They bypass unstable soil, driving deep into the ground until they reach bedrock to transfer your home’s weight.

Pier Installation

A strong support bracket and fastening plate are installed on each pier head. The pier is then anchored to the bracket to secure it in place. For professional expertise, contact Pier Installation Near Me.

A significant amount of excavation is required to prepare for the pier foundation installation process. During this stage, technicians will take measurements and elevations of the area around your home to determine the best place to install the piers. They will then dig holes to a depth of 25-60 feet. This is a more extensive excavation than what is required for other foundation repair methods.

These holes are used to install the piers, which are made from concrete or another type of material. Once the piers are in place, they are checked to ensure that they are level using a spirit or laser level. Once they are, the beams are installed and attached to the piers using brackets.

Helical piers are the most commonly installed pier foundation solution because they offer numerous benefits over other methods of fixing a sinking or settling foundation. This repair method doesn’t require the use of large machinery, and it can be done inside your home, making it a more cost-effective option. In addition, helical piers have an environmental advantage because they don’t require extensive digging and cause minimal disturbance to the soil environment.

Although helical piers are considered environmentally friendly, they do have some drawbacks that you should consider before having them installed in your home. For one, they have a limited load capacity. This means that they aren’t suitable for foundations with heavy structural loads. They are also prone to corrosion, especially in environments with high levels of moisture or salt.

Another issue with helical piers is that they can sometimes lead to the deterioration of other components in your home, such as joists and beams. This is because they transfer the weight of your house from your foundation to these other components. This can lead to problems such as mold and mildew, energy inefficiency, and creaking floors. To avoid this, it is recommended that you follow a maintenance routine for your pier foundation and ensure that water is properly directed away from your home.


During this phase of pier installation, foundation footings are prepared for the pier. The footings are a concrete structure that transfers large super-imposed loads to the solid strata beneath it. The footings are typically made of concrete, but they can also be made of brick, stone, or treated lumber.

The concrete used for pier foundations is typically reinforced with steel to give it superior strength. Concrete is a durable material that is resistant to corrosion and can handle even the heaviest load. It is a very affordable option, and it is easy to work with.

In most cases, a concrete pier is constructed of a series of cylindrical columns that are poured and reinforced. In some instances, these piers are built as monolithic concrete pillars. These types of piers are commonly used in old pier and beam houses where homeowners want to preserve the structure. However, these pillars are very prone to tilting once they start to heave or shift in their location.

A poured pier is less prone to shifting as it distributes the weight of the home evenly across the entire surface. It can be more expensive to build a new pier with this type of foundation, but it is highly effective and extremely long-lasting.

The holes dug for a pier footing are often quite deep. They should be at least 12″ below the frost line, and may be required to be much deeper depending on local soil conditions. Depending on the size of the pier design called for, these holes may be created by hand or with a power auger. The tools required to dig pier holes vary by local requirements and the pier design called for, but in most cases round-point shovels and a post hole digger are adequate.


Foundation piers are typically made from concrete or steel. They consist of a bell-shaped bottom, a straight shaft, and a pier cap. Steel rebar is inserted into the length of each pier for strength. Concrete is then hand poured on location into each pre-drilled hole for each pier. A waiting period of up to 7 days is needed for the fresh concrete to cure and solidify.

The piers are then capped with a steel plate for structural integrity and a surface that resists corrosion. After the piers are in place, they are checked for uniformity using a spirit level or laser level to ensure that they’re perfectly even. This step is especially important if your home has had a basement foundation prior to the installation of the new piers.

There are several benefits of a pier and beam foundation that make it more desirable than slab foundations. These include less excavation and disruption, more visible and accessible areas for electricians and plumbers, and less vibration during seismic activity. They also provide better drainage, as they allow water to safely flow away from the foundation.

In addition, piers are a great solution for homes that experience sticking windows and doors. When a home’s foundation sinks or shifts, it affects the entire structure, including smaller frames like window and door frames. Foundation piers can stabilize and in some cases raise the settled slab back to its original position.

While piers are an effective repair for foundation issues, it is important to remember that they only address the symptoms of the problem. It is not uncommon for what caused the movement in the first place to continue causing problems once piers are installed. For this reason, it’s important to address the root cause of the movement with a professional Bay Area drilling company.


Pier and beam foundations are popular for homeowners looking for stability, easy access to utilities, and protection from soil and water-related issues. They work by elevating a building on vertical piers that are built deep into the ground, with horizontal beams constructed from treated lumber or steel. This design results in a crawl space beneath the foundation that allows for easy access to plumbing and reduces the risks of wood rot, pest infestations, and moisture in the area.

Despite their advantages, pier and beam foundations are not without disadvantages. One of the most significant concerns is the fact that they are subject to moisture problems like other foundation types. Moisture not only decays the wooden piers, but it also causes the soils to swell up, which can cause a shift in the weight of the structure over time. This can lead to sagging, cracking and other problems.

Another drawback is that a pier and beam foundation system requires regular inspections and maintenance to address moisture concerns. The beams are usually pressure-treated lumber, which does not withstand moisture for long. In addition, the soils underneath a pier and beam foundation must be properly graded to evacuate water away from the foundation. This can be a challenging task and is often overlooked in the construction process.

The last major issue with a pier and beam foundation is that it can be difficult to add on to a home if you decide to make changes down the road. This is because the piers are large, solid cylinders that cannot be removed or replaced easily, unlike slab foundations which are made up of a single monolithic piece of concrete that can be accessed from above.

Final Inspection

The final inspection is the last opportunity to ensure that your project complies with industry regulations. It also helps you identify any issues that need to be corrected before a certificate of occupancy is granted. It is important to have a well-developed final inspection checklist that aligns with your specific industry standards and project requirements. This checklist can be used by your team members to perform regular inspections and ensure compliance.

Foundation piers are steel support pillars that go deep into the soil or bedrock to reinforce your home’s foundation. They help distribute the weight of your house to more stable ground, preventing differential settlement that can lead to structural damage. They can even help return your house to its original position if it was built on expansive soil that swells and shrinks over time.

The piers are then connected to beams, which are typically made of treated lumber or concrete. The placement of the beams is crucial, as they must be perfectly level to provide a solid foundation for your home. The installers may need to use a spirit level or laser level to ensure that all the beams are at the same height.

If you’re having foundation repair work done to your home, ask the company about including a drain system to keep the soil from becoming waterlogged. This can prevent hydrostatic pressure that can push down on the piers and cause them to sink.

When it comes to foundation repairs, the helical deck pier is one of the most effective options available today. This patented piering method has become the industry standard for foundation repair because it’s highly versatile and can be used to stabilize most types of structures. They get their name from the helix sections (like a staircase or corkscrew) that are welded to the bottom of each galvanized steel pier shaft. This design makes them much more powerful than push piers and other steel systems, and they can be driven into the soil to prevent differential settlement.
