Are you dealing with tricky soil or building on uneven ground? A pier foundation might be just what you need. It is a reliable choice for homeowners and builders who want maximum stability on challenging terrain or various soil types.

However, is a pier foundation suitable for your project?

In this short guide, we’ll explore the positive and negative aspects of pier foundations to help you determine if it’s the right solution.

What is a Pier Foundation?

In a nutshell, a pier foundation is a special type of building support that uses vertical columns or “piers” to elevate and stabilize the structure above.

These piers are crafted from materials like concrete, steel, or in older homes, wood. Usually, the piers go down below grade and are anchored into a spread footing.

A spread footing is a layer of concrete experts typically reinforce with steel poured in a hole under the pier.

This specialized method of foundation construction is effective for tackling challenging ground conditions such as soft soil or uneven terrain.

One of the biggest advantages of choosing a pier foundation is its practical design. The design of a pier foundation minimizes the impact on the surrounding land, requiring less excavation and preserving more of the natural environment.

Furthermore, it’s a versatile solution suitable for a variety of building projects. It is especially beneficial in flood-prone areas as it raises the structure above potential water levels.

Are you considering this foundation type? It’s a good idea to consult with professionals who understand local conditions and can provide customized solutions.

What are the Benefits of Pier Foundations?

A pier foundation can make a major difference in your construction project. For example, pier foundations offer benefits such as less disruption to the environment, long-term cost savings, and easier access to maintenance. Let’s take a closer look at each of these benefits.

Minimal Environmental Impact

Pier foundations are designed to minimize their impact on the environment. They use narrow, deep placements rather than wide excavations, which helps preserve the soil’s natural structure and reduce erosion. This approach is great for environmentally conscious people working in sensitive areas.

Suitable for Challenging Sites

Is your build site on a slope? Is the ground uneven? If so, a pier foundation could be the ideal solution.

Unlike traditional foundations, which may require expensive and extensive leveling, pier foundations can provide a firm base no matter the surface conditions.

Easy Accessibility for Repairs

One of the perks of choosing a pier foundation is the easy access it provides to the underside of your building. This space allows for straightforward inspections and repairs, making it simpler to handle plumbing or electrical issues without major disruptions.

What are the Drawbacks of Pier Foundations?

Despite its popularity, pier foundations come with a few drawbacks that should be considered before opting for this type of foundation. These include the following:

  • Higher initial cost: One of the main drawbacks of pier foundations is that they are more expensive to construct than slab foundations. This is because pier foundations require more materials, as well as more labor to construct. In addition, pier foundations may require additional excavation work, which can add to the cost.
  • Risk of pest infestations: Another potential drawback of pier foundations is the risk of pest infestations. Because the foundation is raised off the ground, it can be more susceptible to insect and rodent infestations. This can lead to structural damage and the need for costly repairs. Regular pest control measures should be taken to prevent infestations and protect the foundation.
  • Moisture problems: Moisture issues can also be a concern with pier foundations. Because the foundation is elevated, moisture can accumulate underneath the structure, leading to mold and mildew growth. Proper ventilation and drainage should be installed to prevent moisture buildup.
  • Insulation is usually necessary: Insulation is another consideration when choosing a pier foundation. Because the foundation is raised off the ground, it can be more exposed to the elements, leading to higher heating and cooling costs. Proper insulation should be installed to maintain a comfortable indoor temperature and reduce energy consumption.
  • Periodic adjustments are necessary: Pier foundations come with challenges, including the need for regular adjustments.

    Unlike solid concrete slabs that move together, piers can shift independently—especially around the edges of your home where soil moisture varies. Due to this, you may have to deal with uneven settling and bending in different parts of your house, often increasing costs.

    Traditional pier systems usually can’t be adjusted easily, which makes the adjustment process difficult and disruptive. It often requires removing the house beams from the piers, lifting the structure with hydraulic jacks and blocks, and placing steel shims between the pier and the beam before reconnecting them. This method takes a lot of work and can increase the risk of other structural problems.

    Only top foundation repair offers the Adjust-A-Pier system. This system simplifies the adjustment process by removing the need for hydraulic jacks, detaching beams, or adding shims.

Is a Pier Foundation Suitable for Your Project?

To determine whether a pier foundation is the best solution for your building project, consider the following four main factors.

Assess the Soil and Terrain Conditions

Pier foundations work best in demanding conditions. If you are dealing with an uneven building site or one with more challenging soil, such as sand or clay, a pier foundation may be the best option.

Consider the Building Load

Think about the size and weight of your planned structure. A pier foundation is ideal for lighter buildings like smaller commercial spaces and residential homes. If you want to build something heavier, you will want to ensure the foundation design is strong enough to handle the load.

Consider the Environmental Impact

Do you want to preserve the natural setting of your construction site? If so, a pier foundation may be right for you. The installation process is minimally invasive, so it won’t cause major damage to the surrounding vegetation and land.

Think About Your Budget

The cost of pier foundations can vary depending on a number of factors, including the size of the building, the depth of the piers, and the type of soil conditions. However, on average, pier foundations tend to be more expensive than slab foundations but less expensive than basement foundations.
