Are Push Piers Better Than Helical Piers?

Advantages of push piers:

• Ideal for heavy structures since the building’s weight helps drive the piers deep into the ground

• Reach bedrock or highly compact soil, making them effective in areas with unstable surface soil

• Provide reliable, long-lasting foundation support once installed

Disadvantages of push piers:

• Require significant weight to be effective, which can make them unsuitable for lighter structures

• Less versatile compared to helical piers, especially in soil with varying densities

• In some cases, only stabilize the foundation rather than lift it back to its original position

How Helical Piers Work

Helical piers have screw-like helical plates that allow them to be screwed into the ground rather than pushed. This installation method does not rely on the weight of the structure, making it a versatile option for a variety of projects, including residential homes, decks, and commercial foundations.

Advantages of helical piers:

• Work in most soil conditions since they screw into the ground rather than relying on downward force

• Do not require a heavy structure for installation, making them suitable for lighter buildings

• Can support weight immediately after installation, reducing project timelines

• Used for a wide range of applications, including new construction and foundation repair

Disadvantages of helical piers:

• May not be ideal in areas with shallow bedrock where the helical plates cannot properly engage

• Require certified installers to ensure proper installation and long-term stability

• Can lose some effectiveness in high water table conditions

Comparing the Installation Methods

The key difference between push piers and helical piers is how they are installed.

• Push piers are installed by hydraulic jacks, which drive the steel piers into the ground using the weight of the structure.

• Helical piers are installed by a motorized drive head that screws them into the ground until they reach competent soil.

Since push piers rely on a structure’s weight, they are often preferred for large commercial buildings or multi-story homes. Helical piers, however, can be installed before construction begins, making them an excellent option for new foundations and lighter structures.

Cost Considerations

When evaluating foundation repair costs, both push piers and helical piers require specialized equipment and skilled labor. However, there are some differences in price:

• Push piers tend to have higher installation costs due to the need for hydraulic pressure systems and deeper installation.

• Helical piers are often more cost-effective because they can be installed quickly with smaller equipment.

While helical piers typically have lower labor costs, the overall cost depends on soil conditions, foundation type, and the number of piers needed.

Choosing the Right Pier for Your Foundation

The best option depends on several factors, including:

• Weight of the structure – push piers work best for heavier buildings, while helical piers are more versatile.

• Soil conditions – helical piers perform well in a variety of soil conditions, while push piers are best suited for deep stable soil.

• Installation needs – if immediate load-bearing support is required, helical piers are often the better choice.

Conclusion

There is no one-size-fits-all answer to whether push piers or helical piers are better. Push piers are ideal for heavy structures that need deep stabilization, while helical piers provide versatile support for a range of buildings. The right solution depends on foundation conditions, soil type, and specific structural needs.
