What Are Helical Piers?
Helical piers are deep foundation solutions designed to stabilize and support structures experiencing foundation settlement. These piers consist of a steel shaft with helical plates welded onto them, resembling a giant screw. By twisting into the soil, they provide a firm anchorage, transferring the structural load to deeper, more stable ground layers.
When Are Helical Piers Used?
Helical piers are utilized in a variety of situations, including:
- Repairing foundations of homes and buildings experiencing settlement.
- Supporting new construction in areas with unstable or weak soil.
- Stabilizing decks, patios, and other structures susceptible to ground movement.
- Reinforcing commercial buildings, bridges, and industrial structures where deep foundational support is needed.
How Are Helical Piers Installed to Repair an Existing Foundation?
The installation of helical piers involves the following steps:
- Site Assessment: Experts evaluate the foundation issues and determine the number and placement of piers needed.
- Pier Installation: Using hydraulic machinery, the piers are screwed into the ground until they reach a stable soil layer.
- Load Transfer: Once the piers are secured, brackets are attached to the foundation footing to transfer the building’s weight onto the piers.
- Final Adjustments: The system is tested for stability before backfilling any disturbed areas.
This minimally invasive process requires no extensive excavation and can be completed within a few days, depending on the project size.
Benefits of Helical Piers
Helical piers offer several advantages, including:
- Immediate Load-Bearing Capacity: Once installed, they can support structural weight immediately.
- Minimal Disruption: Unlike traditional underpinning methods, helical piering requires minimal excavation and disturbance to the property.
- Versatility: They can be used in various soil conditions and for both residential and commercial projects.
- Longevity: Made from corrosion-resistant steel, helical piers provide long-term foundation stability.
- Cost-Effective: They are a more affordable alternative to complete foundation replacement.
Signs Your Foundation Might Need Helical Piers
If you notice any of the following signs, it may indicate foundation issues that require helical pier installation:
- Cracks in walls, floors, or ceilings
- Uneven or sloping floors
- Doors and windows that stick or won’t close properly
- Gaps between walls and ceilings or floors
- Chimney separating from the house
Ignoring these signs can lead to more severe structural damage and costly repairs.
How Much Do Helical Piers Cost?
The cost of helical pier installation varies depending on factors such as:
- The extent of foundation damage
- The number of piers required
- Soil conditions
- Accessibility of the site
- Labor and material costs
On average, helical piers can cost between $1,500 to $3,000 per pier, including installation. A professional assessment will provide a more accurate estimate based on your specific needs.
What Causes Foundation Problems?
Foundation problems can arise due to several factors, including:
- Soil Movement: Expansive clay soils shrink and swell with moisture changes, leading to foundation shifting.
- Poor Drainage: Excess moisture around the foundation can cause soil erosion and settlement.
- Tree Roots: Large trees near a structure can draw moisture from the soil, causing instability.
- Improper Construction: Inadequate foundational support during construction can lead to premature settling.
- Plumbing Leaks: Water leaks beneath the foundation can weaken the soil and cause structural instability.
