Using helical piles will save you time and money, since they don’t require any excavation, concrete curing time or site repairs. Also, ensuring your project’s stability will prevent additional costs resulting from probable soil movement.
Helical piles vs concrete: which foundation should you choose?
The choice between helical piles (screw piles) and concrete foundations depends on several factors, including soil conditions, construction timelines, and budget. Helical piles stand out for their speed and simplicity of installation. They are mechanically screwed into the ground until they reach a stable load-bearing layer—without the need for excavation or concrete. In contrast, concrete foundations require multiple steps such as excavation, formwork, pouring, and curing time, which can significantly delay construction. For most residential projects (decks, home additions, sheds), helical piles are now a faster, more flexible, and cost-effective solution.
Are helical piles better than concrete?
In many cases, yes, especially when speed, stability, and cost efficiency are priorities. Unlike concrete, helical piles:
- require no excavation
- allow you to build immediately after installation
- provide real-time verified load-bearing capacity during installation
They are also designed to better withstand soil movement caused by freeze-thaw cycles, reducing the risk of cracks and long-term settlement issues. Additionally, their installation has a lower environmental impact, as it minimizes the use of concrete and reduces site disruption.
Helical piles are often the better choice for light to medium structures and variable soil conditions.
Foundation: helical piles or concrete—what’s the difference?
The main difference lies in the installation method and load transfer.
- Helical piles act like large steel screws, anchored deep into the ground until they reach stable soil.
- Concrete foundations, on the other hand, rely mostly on surface support and require extensive site preparation to prevent movement.
- Another key difference: Helical piles offer a fast, clean, and immediate installation, while concrete involves more logistical constraints and waiting time.
| Criterion | Helical Piles (Screw Piles) | Concrete Foundations |
|---|---|---|
| Installation time | A few hours | Several days to weeks |
| Excavation | None | Excavation required |
| Construction start | Immediate | After concrete curing |
| Overall cost | Optimized | Higher (labor + materials) |
| Soil stability | Deep anchoring (bearing soil) | Depends on preparation |
| Freeze/thaw resistance | Very high | Risk of cracking |
| Site access | Easy even in restricted areas | More complex |
| Environmental impact | Low | High |
Helical piles provide a faster, cleaner, and often more cost-effective foundation solution than concrete. They are especially well-suited for residential projects and challenging soil conditions, while ensuring long-term stability.
