What is a Helical Pier—and Why It Matters for Your Outdoor Project

When you’re investing in a patio, retaining wall, or outdoor living space, everything comes down to one thing: the foundation. If the ground beneath your project isn’t stable, it doesn’t matter how good it looks—it will fail over time.
That’s where helical piers come in.
At Hannah Outdoor Designs, we use helical piers when we encounter weak, unstable, or shifting soil—because building on a bad base is not an option.
🔩 What Is a Helical Pier?
A helical pier is a steel foundation system that is mechanically screwed into the ground until it reaches stable, load-bearing soil.
It looks similar to a large metal shaft with helix plates (like screws) attached. These plates allow the pier to be advanced deep into the ground, anchoring into soil that can properly support weight.
Once installed, the pier acts as a structural support system, transferring the load of your project from weak surface soil to stronger soil below.
🏗 What Is the Purpose of a Helical Pier?
The purpose of a helical pier is simple:
👉 To create a stable foundation where the existing soil cannot support the structure.
This is critical in areas where you may have:
Loose or uncompacted soil
Fill dirt from previous construction
Clay soils that expand and contract
Organic material (roots, old stumps)
Erosion-prone areas
Slopes or hillside properties
Instead of hoping the ground holds, we engineer a solution that guarantees stability.
⚠️ Why Weak Soil Is a Problem
If you build directly on weak soil, here’s what typically happens over time:
Patios begin to settle or sink
Retaining walls shift or lean
Concrete cracks
Pavers become uneven
Drainage patterns fail
In Georgia, this is especially common due to:
Expansive clay soils
Heavy rainfall
Erosion on sloped properties
These issues don’t show up immediately—but when they do, they’re expensive to fix.
🔧 How Helical Piers Solve the Problem
When we install helical piers, we:
Drive the pier deep into the ground (often 20–50+ feet depending on conditions)
Reach stable, load-bearing soil
Attach brackets or supports to your structure
Transfer the load away from weak soil
The result:✔ No settling✔ No shifting✔ Long-term structural integrity
📍 When Do You Need Helical Piers?
We typically recommend helical piers when building:
Large paver patios
Retaining walls with significant height
Outdoor kitchens or chimneys
Structures near slopes or erosion zones
Areas with known poor soil conditions
If we uncover weak soil during excavation, we don’t ignore it—we fix it.
💡 Why This Matters to Homeowners
Most contractors won’t talk about soil conditions—they’ll just keep building.
At Hannah Outdoor Designs, we take a different approach: We identify problems early and solve them the right way, even if it requires more work upfront.
Because your outdoor space should:
Stay level
Drain properly
Last for years
Not settle, crack, or fail.
🎯 The Bottom Line
Helical piers are not just an upgrade—they’re a solution to a serious problem.
If your soil can’t support your project, the only right move is to stabilize it properly before building.
At Hannah Outdoor Designs, we focus on what’s beneath the surface—because that’s what determines whether your project lasts.
