When the soil beneath a foundation can no longer support the weight of the structure above it, the foundation begins to sink. Helical piles, also called helical piers, are one of the most effective and reliable solutions because they bypass failing soil and transfer the load to stable ground deeper below.

Foundation settlement is serious, but it is also highly fixable when it’s diagnosed correctly and stabilized early. If you’re seeing cracks, sticking doors/windows, sloping floors, or gaps that suggest one part of the home has dropped relative to another, settlement may be the cause.

A foundation is only as stable as the soil supporting it. Settlement happens when soil loses capacity due to:

• Erosion/washout: water movement removes fine soil particles and creates voids
• Poor fill/compaction: fill soil continues compressing long after construction
• Expansive/unstable soils: clay-rich soils swell when wet and shrink when dry
• Organic decomposition: buried roots/debris compress as they break down

In all cases, the correct long-term approach is the same: bypass failing soil and anchor the foundation to stable bearing below—which is exactly what helical piles do.

A major advantage of helical pier installation is that capacity can be evaluated during installation by monitoring torque, the resistance the soil provides against rotation. There’s a known relationship between torque and load capacity in the soil being penetrated.

This gives real-time feedback about what’s happening underground, rather than relying only on a predetermined depth.

Once the helical pile reaches the required depth and capacity:

• A steel bracket is attached to the foundation footing
• The foundation load is transferred through the bracket, down the pile, into stable soil
• Hydraulic lifting can raise the settled section back toward its original position

Important expectations about lifting

• Lift is the goal, but full recovery isn’t always possible (depends on time, structure condition, soil response)
• Stabilizing and lifting does not automatically “erase” past damage—cosmetic repairs often follow (drywall, trim, masonry, siding)

Helical piles can be designed to carry significantly more load than is currently present, allowing for long-term stability and even future changes (additions/renovations) when engineered appropriately.
