When Helical Pier Installation Is Needed for Pools and Structures

January 9, 2023

When building a pool, retaining wall, or structure, what’s below the surface matters just as much as what’s visible. In areas with unstable or shifting soil, helical pier installation is often required to provide long-term structural support and prevent costly damage.

Understanding when helical piers are needed — and why they matter — can help homeowners and builders protect their investment and avoid future foundation issues.

What Is Helical Pier Installation?

Helical pier installation is a foundation support method that uses steel piers with helical (screw-like) plates. These piers are mechanically driven deep into stable soil, creating a secure foundation that supports heavy loads.

Unlike traditional concrete footings, helical piers transfer weight to load-bearing soil layers below the surface, making them ideal for areas with poor soil conditions.

Helical pier installation is commonly used for:

  • Swimming pools
  • Retaining walls
  • Structural foundations
  • Additions and outdoor structures

When Are Helical Piers Necessary?

Not every project requires helical pier installation, but certain conditions make them essential. Helical piers are often recommended when:

  • Soil is expansive or unstable
  • The project is near existing structures
  • There is a risk of settling or soil movement
  • The structure requires engineered support
  • Pools are built on slopes or fill dirt

In these situations, helical pier installation provides the stability needed to protect the structure over time.

Why Helical Pier Installation Is Critical for Pools

Swimming pools place significant weight on the surrounding soil. Without proper support, shifting ground can cause cracks, movement, and structural failure.

Helical pier installation helps:

  • Prevent pool shell movement
  • Support pool walls and bond beams
  • Reduce the risk of settling or shifting
  • Improve long-term structural integrity

Pool builders often rely on professional excavation contractors to handle helical pier installation with precision and accuracy.

The Helical Pier Installation Process

A professional helical pier installation follows a detailed process to ensure performance and reliability:

1. Site Evaluation

Soil conditions and load requirements are reviewed to determine the number and placement of helical piers.

2. Precision Installation

Helical piers are mechanically driven into the ground until they reach stable load-bearing soil.

3. Load Verification

Installation torque is monitored to confirm each pier meets engineered specifications.

4. Integration With Construction

Once installed, the piers are tied into the pool or structure foundation to provide support.

Proper helical pier installation requires experience, specialized equipment, and coordination with builders and engineers.

Benefits of Helical Pier Installation

Choosing helical pier installation offers several advantages over traditional foundation methods:

  • Immediate load-bearing capacity
  • Minimal soil disturbance
  • Faster installation timelines
  • Long-term stability
  • Suitable for tight or limited access sites

These benefits make helical piers a preferred solution for both residential and commercial projects.

Common Mistakes to Avoid With Helical Piers

Improper installation can reduce the effectiveness of helical piers. Common mistakes include:

  • Incorrect pier placement
  • Insufficient depth
  • Ignoring soil conditions
  • Using unqualified installers

Working with an experienced excavation contractor ensures helical pier installation is performed correctly and meets project requirements.

How Helical Piers Support Long-Term Performance

One of the biggest advantages of helical pier installation is long-term reliability. When installed correctly, helical piers help prevent:

  • Structural movement
  • Cracking
  • Uneven settling
  • Costly future repairs

This makes them an excellent solution for projects where stability is critical.
