Helicon has been installing helical pier systems across Florida since 2004, helping homeowners protect their pools from costly settling or cracks. Whether you’re building from scratch or fixing an existing issue, it’s what’s under your pool that matters most.
In this blog, you will learn:
- What helical piers are and how they support swimming pools
- Why do they outperform traditional foundation methods in Florida
- How to choose the right pier design for your pool project
Let’s break it down!
What Are Helical Piers for Pool Support?
Helical piers support your pool by reaching deep into stable soil layers. They work well in soft or shifting ground, keeping your pool level and secure over time. Understanding how they work, how they compare to traditional methods, and the benefits they offer can help you choose the right support system.
How Helical Piers Work?
Helical piers are steel shafts with screw-like plates called helices attached along the shaft. Installers screw these piers into the ground until they reach firm soil or bedrock. As they turn the piers, the helices dig deep and anchor the pier securely.
The piers transfer your pool’s weight from loose or weak soil to strong layers below, stabilizing the pool foundation and preventing sinking or shifting. Helicon uses high-quality steel piers engineered to handle heavy loads and Florida’s unique soil conditions.
Installation causes minimal disturbance to your site. Because installers place the piers vertically, they require less digging than traditional footings. This means faster work and less mess around your pool area.
Comparison With Traditional Foundation Methods
Traditional pool foundations often use concrete footings or slabs poured on or just below the surface. These footings rely on the strength of upper soil layers, which can be unstable in many areas, including Florida.
Helical piers go deeper, bypassing weak or shifting soils that can cause cracks or settlement in concrete slabs. Unlike large, wide footers that need extensive excavation, installers place helical piers with simple equipment and cause less site disruption.
| Feature | Helical Piers | Traditional Footings |
|---|---|---|
| Depth of support | Deep into stable soil | Shallow, depends on surface soil |
| Installation time | Faster, less excavation | Slower, requires digging |
| Soil adaptability | Works in many soil types | Less effective in soft soils |
| Load distribution | Transfers load to firm layers | Relies on shallow soil strength |
Helical piers offer a practical option if your soil is soft or uneven.
Key Benefits for Swimming Pools
Using helical piers for your pool support offers key advantages:
- Long-term stability: They prevent uneven settling or sinking that can crack pool walls and decks.
- Protection from soil issues: Helical piers work well in Florida’s sandy or clay soils, reducing problems related to soil shifting or erosion.
- Less excavation: Smaller, cleaner installs save time and reduce disruption to your landscaping.
- Quick installation: Projects usually finish faster than with traditional foundations, letting you enjoy your pool sooner.
Our helical pier systems hold your pool firmly and safely. The steel piers are also coated to resist corrosion, ensuring they last for the life of your pool.
Choosing Helical Piers for Your Pool Project
When adding helical piers to support your pool, it’s essential to understand your site’s soil, how much weight the piers must carry, and which pier design fits your needs. These choices affect the pool’s stability and safety over time.
Assessing Pool Site Conditions
Start by checking the soil type where your pool will be built.
Sandy or loose soils need stronger support than firm clay or rock. Look for signs of shifting or erosion, which can cause future problems.
A professional soil test is often necessary. It shows the depth of stable soil and any underground issues like sinkholes. This information guides the length and size of the piers needed.
Also consider water drainage and nearby vegetation, as they affect soil moisture and pressure. Proper site assessment helps avoid costly repairs later.
Load-Bearing Capacity Considerations
Your pool’s overall weight, including the structure, water, and decking, directly affects the type of helical piers required. Here’s what you need to consider when evaluating load capacity:
- Pool and Deck Weight: Heavier pools with concrete shells or extended decking require piers that can handle greater loads. This ensures the foundation stays stable even under long-term pressure.
- Shaft Size: Helical piers come in different shaft thicknesses. Thicker shafts can support more weight without bending or failing, making them ideal for larger pools or deeper installations.
- Helix Diameter: Larger helix plates provide better soil grip and distribute weight more effectively. This is important for pools built on softer or looser soils.
- Load Rating Accuracy: The chosen pier system must match—or exceed—your pool’s total estimated weight. Underestimating the load can lead to gradual sinking or uneven settling.
- Professional Load Calculation: Trustworthy providers like Helicon calculate exact load requirements based on your soil type and pool design, ensuring the right pier configuration for long-lasting support.
Selecting the Right Pier Design
Helical piers come in multiple designs, including single, double, or triple helix blades.
The number and size of blades affect their holding power. Standard pier lengths range from 4 to 7 feet, but can be extended if needed. Powder-coating or galvanization options protect piers from corrosion in wet environments.
Depending on soil and load needs, choose piers with certified steel shafts sized from 1 1/4” to 2 1/4” square. Making the right choice ensures a solid and long-lasting pool foundation.
Installation Process for Pool Helical Piers
Installing helical piers for your pool involves careful planning, precise steps, and the right tools. Each part of the process ensures your pool’s foundation is strong and stable in Florida’s soil conditions.
Below, you’ll find guidance to help you understand how this system comes together.
Pre-Installation Planning
Before any work begins, a detailed site evaluation is necessary.
You or your contractor will inspect the soil to determine how deep the helical piers must go. This helps the piers reach firm, load-bearing soil below soft or unstable layers.
You’ll also discuss the size and number of piers required. Helical piers come in different shaft sizes and helix blade configurations to match your pool’s size and weight. Helicon recommends planning based on soil type, pool design, and local building codes.
Arrange permits and early access to the site. This preparation keeps the installation smooth and meets safety standards.
Step-by-Step Installation Procedures
The installation starts by marking pier locations around your pool’s perimeter.
- Installers use a small, portable machine to screw the helical piers into the ground. This process is quiet and low-impact compared to traditional piling.
- Installers twist each pier into position until it reaches stable soil, confirmed by measuring torque resistance. They add extensions if the soil is deep or varied.
- After the piers are installed, brackets are attached at the surface to connect the pool’s foundation. This connection stabilizes the pool and helps prevent it from settling or shifting.
During installation, workers take measurements to ensure each pier is aligned and level.
Timeframe and Required Equipment
Installing helical piers usually takes one to three days, depending on the pool size and soil conditions. The key equipment includes a portable torque machine for tight access and tools for measuring and leveling each pier.
Since heavy machinery isn’t needed, the process causes less disruption to your property. Our equipment allows the team to work efficiently while maintaining safety and minimizing site damage.
Having the right team and tools ready before starting will avoid delays and keep the job on schedule.
Long-Term Performance and Maintenance
Maintaining the strength and stability of your pool foundation is key to safety and durability. Regular checks and proper care help avoid costly repairs and keep your helical piers working as designed.
Ensuring Foundation Stability
Your helical piers transfer the pool’s weight to strong underground soil layers, keeping the foundation steady even if the surface soil shifts due to weather or moisture changes.
To maintain stability, avoid excess water pooling near your pool area. Proper drainage is essential because standing water can loosen soil around the piers. Also, avoid heavy loads or structures placed close to the pool edge, which can stress the foundation.
Helical piers are made with durable, galvanized steel designed to resist corrosion. Your foundation works best when soil conditions remain consistent and well-managed.
Inspection and Upkeep Tips
Regular inspections help catch minor issues before they become big problems. Check your pool deck and surrounding concrete for cracks, uneven settling, or tilting.
Look for soil erosion near piers or unusual sinking spots. Pay attention after heavy rain or drought, as extreme weather can affect soil moisture.
A simple checklist:
- Check for cracks or gaps in concrete
- Look for signs of soil erosion or sinking
- Confirm proper drainage around the pool
- Schedule professional inspections every few years
If you notice unusual changes, consult with a specialist like Helicon early to evaluate pier performance and prevent damage.
Signs of Potential Issues
Watch for these signals that your pool support may need attention:
- Cracks widening along pool walls or deck slabs
- Pools or decks that tilt or feel uneven underfoot
- Doors or windows near your pool that suddenly become hard to open or close
- Soil pulling away from pier locations or settling unevenly
If you spot these, act quickly. Timely maintenance and repair ensure your helical piers continue working well.
