What is the difference between using helical piers or concrete footers?

The main difference between helical piers and concrete footers comes down to installation method, performance in various soil conditions, and project timelines:

• Concrete Footers: These are traditional foundations made by excavating holes, installing forms, and pouring concrete, which then cures to provide support. This method works well in stable, well-drained soils but requires heavy equipment, longer project timelines (due to curing time), and can be impacted by weather conditions.
• Helical Piers: These are steel shafts with spiral plates that are screwed deep into the ground until they reach stable soil. Installation is quick, requires minimal excavation, and can be performed in all weather—even when it’s too wet or cold for concrete. Helical piers are ideal for challenging soils, sloped sites, or locations with trees and roots.

Key Comparisons:

• Speed: Helical piers can be installed much faster (usually within a day), whereas concrete footers need excavation and several days for concrete to cure.
• Soil/Conditions: Helical piers excel in poor, soft, or unstable soils. Concrete footers work best in solid, undisturbed ground.
• Disturbance: Helical piers cause less disruption to landscaping and require less heavy machinery.
• Weather Flexibility: Helical piers can be installed year-round, while rain or freezing temperatures can delay concrete work.
