Which Pier System is Best for Underpinning a Sinking Foundation?

When comparing pier systems for a sinking foundation, helical piers are often considered the best choice, particularly for residential properties and projects in areas with expansive clay soils like the Colorado Front Range. While the ideal solution depends on a professional site inspection, helical piers offer several distinct advantages:

Immediate Load Capacity: Unlike push piers, which often require concrete to cure and add days to a schedule, helical piers can accept structural loads immediately after installation.
Faster Installation: These systems can be installed up to 66% faster than push piers in poor soil conditions because they are screwed into the ground using hydraulic torque rather than being driven by heavy hydraulic force.
Minimal Disruption: Helical piers use lighter, more maneuverable equipment. This makes them ideal for tight spaces and minimizes damage to landscaping and existing structures compared to the excavation needed for push piers.
Soil Performance: They are highly effective in weak or variable soil strata. Push piers, by contrast, rely on the structure’s own weight for reaction force and may require deep excavation that can further destabilize problematic ground.

While push piers are a time-tested option for heavy commercial loads or sites where stable bearing strata are easily accessible, helical piers are typically preferred for their efficiency, speed, and minimal site impact.
