Helical Piers vs Push Piers: Which is Best for Your Foundation?
As a local contractor with years of experience serving Long Island, Brooklyn, and Queens, I’ve seen firsthand the foundation challenges homeowners face—especially with our unpredictable soils and coastal conditions. When it comes to stabilizing your home’s foundation, helical piers vs. push piers is a common comparison that property owners are interested in comparing, and it’s because they are two of the most effective solutions. But depending on your specific situation, one option may be better suited than the other.
Helical piers are the go-to choice for new construction and problem soils, offering unmatched longevity and performance. Whether you’re in Massapequa dealing with sandy soils or in Rockaway needing solid support for a beachfront property, helical piers outperform traditional foundations on every count. Push piers, on the other hand, are more commonly used for fixing existing foundation problems, especially in older homes with settlement issues.
In this article, we’ll break down the differences so you can make the right choice to protect your property for the long term.

What Are Helical Piers?
Helical piers are long steel shafts with screw-like plates at the end, designed to be drilled deep into the soil to stabilize foundations in shifting or weak ground conditions. These piers are twisted into the ground using hydraulic machinery, anchoring securely into stable soil layers. Because they don’t require extensive excavation, helical piers are a versatile solution for both new construction and foundation repair projects, particularly in areas with challenging soil conditions like those found in Long Island, Brooklyn, and Queens.
Helical piers are ideal for properties in coastal or sandy areas, where soil movement can threaten the stability of a foundation. They are effective in a variety of soil types, including loose or expansive soils, and provide long-term structural support for homes, commercial buildings, and even decks. While helical piers excel in these conditions, push piers offer a different solution, particularly for homes already facing settlement issues.
What Are Push Piers?
Push piers are hydraulically driven steel pipes that are installed under the foundation to provide support by reaching load-bearing soil layers deep beneath the surface. Unlike helical piers, which are screwed into place, push piers are driven straight into the ground using the weight of the structure as leverage until they reach stable soil.
Push piers are most commonly used in retrofit applications, particularly when a home’s foundation has settled or shifted due to poor soil conditions. They are designed to lift and stabilize sinking foundations, restoring structural integrity to buildings that may have already shown signs of damage, such as cracks in the walls or uneven floors. This makes push piers a reliable option for homeowners in Queens or Brooklyn, where older homes are prone to settlement issues.
Key Differences Between Helical Piers and Push Piers
Although both helical piers and push piers are designed to stabilize foundations, there are critical differences in how they work, their installation process, and where they are most effective. Understanding these differences can help you choose the best solution for your property in Long Island, Brooklyn, or Queens.
Helical Piers vs Push Piers:
- Installation Method: Helical piers are screwed into the soil using hydraulic machinery, while push piers are hydraulically driven into the ground until they reach load-bearing soil.
- Ideal Soil Conditions: Helical piers are better suited for weaker or shifting soils, while push piers are more effective in reaching deeper, stable soil layers.
- Foundation Type: Helical piers are versatile and can be used for both new construction and foundation repairs. Push piers are typically used for repairing existing foundations that have already settled.
- Cost: Push piers can sometimes be less expensive for repair projects, but overall costs depend on soil conditions, the size of the structure, and specific foundation needs.

| Key Differences | Helical Piers | Push Piers |
|---|---|---|
| Installation Method | Screwed into the soil | Driven into the soil |
| Ideal Soil Conditions | Weaker or shifting soils | Deeper, stable soil layers |
| Foundation Type | New construction or repairs | Repairing existing foundations |
| Cost | Depends on soil and structure | Can be less expensive for repairs |
When to Choose Helical Piers
Push piers are often used in foundation repair projects when a building has already settled and needs to be lifted back into place. These piers are driven deep into the ground to reach stable, load-bearing soil, making them an ideal choice for heavier structures that have experienced significant settlement.
Key scenarios for using push piers include:
- Heavy Structures: Push piers are more effective for stabilizing larger, heavier buildings, such as commercial properties or multi-story homes.
- Deeper Soil Layers: They are ideal when the foundation needs to reach deeper, more stable soil layers that can support the weight of the structure.
- Cost-Effective for Repair: For homes or buildings that have already settled, push piers can sometimes be a more cost-effective solution for lifting and stabilizing the foundation compared to alternative methods.
For situations where the foundation has already experienced significant movement, push piers provide a reliable and durable solution.
Factors to Consider Before Choosing Between Helical and Push Piers
Several key factors should be considered when choosing between helical piers and push piers, including soil conditions, building weight, and project costs. Each foundation system has its own strengths, and the best option depends on your property’s specific needs.
Factors to Consider Before Choosing:
- Soil Conditions: Helical piers are better suited for softer or unstable soils, such as those found in coastal areas of Long Island and Queens. Push piers work best when they can be driven deep into stable, load-bearing soil layers, typically found in areas where the top layers of soil are weaker.
- Foundation Status: If your foundation is still in good condition but requires additional support, helical piers are ideal. If your foundation has already settled or shifted, push piers are often the best option to lift and restore it to its original level.
- Project Budget: Costs can vary depending on the number of piers required and site conditions. Push piers may be more affordable for foundation repairs, but helical piers can provide long-term value for new construction or preventative foundation support.
- Installation Speed: Helical piers are often quicker to install, especially for new construction projects. Push piers may take longer to install, particularly in retrofit situations where precision is key to reaching load-bearing soil.

Long-Term Stability and Maintenance of Helical and Push Piers
Both helical piers and push piers offer long-term stability, but their effectiveness over time depends on proper installation and routine inspections. With professional installation, these systems can provide decades of reliable support.
- Helical Piers: Known for their ability to resist corrosion, helical piers require minimal maintenance. Their galvanized steel composition ensures durability, even in challenging soil conditions like those found in Long Island and Brooklyn.
- Push Piers: Push piers can also provide lasting stability but must reach deep, load-bearing soil to be effective. Periodic inspections are important to ensure the piers are performing as expected.
- Maintenance Needs: Both systems are low-maintenance but should be checked regularly to ensure the foundation remains stable, particularly after significant weather events or soil shifts.
Final Thoughts on Choosing Between Helical and Push Piers
Ultimately, the choice between helical piers and push piers comes down to soil conditions, building weight, and the specific needs of your foundation. Helical piers offer excellent support in softer soils and are ideal for new construction, while push piers are best suited for heavier structures and foundation repair.
