What Are Helical Piers and How Do They Fix Foundations?

Helical piers look like large screws. The spiral plates bite into the ground as the shaft is turned, pulling the pier deeper until it reaches load-bearing soil. Once installed, the pier carries the weight of the foundation above, preventing further settling.

The process involves attaching brackets to your foundation and using hydraulic equipment to turn the piers. The depth depends on soil conditions and the weight of your home. The pros use torque readings to confirm the pier has reached solid ground, then lock the bracket to hold the foundation steady.

• Steel shafts resist corrosion and last decades
• Spiral plates provide grip in various soil types
• Installation causes minimal disturbance to your yard
• Piers can be removed or adjusted if needed
• Works for both interior and exterior foundation issues

Water is a common cause of foundation problems. Heavy rain, plumbing leaks, or poor drainage can saturate the soil, causing it to expand and contract. Over time, this movement can lead to settling or heaving of your foundation.

If you have water damage inside your home, address the source first. Drying out the area and fixing leaks can reduce further soil movement. In Doral, the humid climate means moisture is a constant factor, so keep gutters clear and slope landscaping away from your home.

The cost of helical piers varies widely. It often ranges from $1,000 to $3,000 per pier, but the total depends on the number of piers, soil conditions, and the accessibility of your foundation. A full project can range from $5,000 to $20,000 or more.

Helical piers are designed to last for the life of your home, often 50 years or more. They are less invasive than concrete piers and can be installed in tight spaces. Regular inspections can help ensure they continue to perform well.
