Helical pilings, also known as helical piers, screw piers, or earth anchors, offer a technologically advanced alternative to traditional foundation repair and stabilization methods.
These steel shafts with helical plates are turned into the ground much like a screw into wood, providing a solid footing for various types of structures.
Their versatility and ease of installation have made them a popular choice for homeowners facing foundation issues or constructing new buildings on unstable soil.
While traditional foundation repair methods can be invasive and time-consuming, helical pilings provide a less disruptive and often more cost-effective solution.
They are particularly beneficial in situations where soil conditions are challenging and can be customized to support a wide range of weight requirements.
Whether for residential homes, commercial buildings, or even bridges and boardwalks, helical pilings can ensure the stability and longevity of a structure’s foundation.

Helical pilings, also known as screw piles, are a deep foundation solution adopted in both residential and commercial construction to provide structural stability.
Helical pilings are a type of foundation system consisting of long, slender columns with one or more helix-shaped blades attached.
These piles are driven into the ground using rotational force, which allows for minimal soil disturbance and immediate load transfer capabilities.
The concept of helical pilings dates back to the early 1830s and was originally employed in nautical contexts, primarily for mooring and lighthouses.
The industrial revolution saw innovations in helical pile design, making them a more prevalent choice in construction.
Despite a period of reduced popularity due to steam-powered pile driving, helical piles have experienced a resurgence.
They are now recognized for their versatility and effectiveness in soil stabilization and geotechnical engineering.
The Components of a Helical Piling System
Primary Components:
These components work in unison, allowing helical pilings to be precision-driven to engineered depths, providing robust foundational support for structures of varied sizes, from a small porch to a high-rise.
Their design effectively mitigates issues related to different soil strata, making screw piles a reliable solution for a multitude of projects.
Helical pilings offer homeowners a reliable and efficient solution for foundation support.
They bring together cost-effectiveness, robust durability, a streamlined installation process, and a lower environmental impact compared to traditional methods.
Durability and Longevity
Helical pilings are engineered for strength and longevity. Their durability is evidenced by their ability to support both light and heavy structures, from small residential extensions to large commercial buildings.
They can handle a wide range of weights, up to and exceeding 1,125 million lbs, highlighting their suitability for a multitude of applications.
Installation Process
One notable advantage of helical pilings is their simplified installation process. Unlike traditional piling methods that may require large machinery, helical pilings can be installed with common construction equipment.
This reduces the need for extensive site preparation, minimizes disruption, and can be performed in a variety of weather conditions, adding to their cost-effectiveness.
Environmental Impact
The environmental impact of construction is an ever-growing concern. Helical pilings score high in this aspect due to their minimal site disruption.
They do not generate spoil that needs to be disposed of, resulting in a smaller carbon footprint.
Furthermore, the equipment used for installation typically has a lower environmental impact compared to heavy-duty piling rigs.

Proper installation of helical pilings is critical for ensuring the stability and longevity of a structure’s foundation.
This process involves meticulous planning and follows a specific step-by-step procedure adhering to building regulations and weather considerations.
Planning and Design
Before any physical work begins, a comprehensive plan must be in place. A qualified contractor selected for their expertise in helical pile systems will generally conduct a soil analysis to design the pile system.
They will account for building codes and acquire permit requirements to ensure compliance with local regulations.
Careful consideration is given to weather conditions, as they can affect the timeline and safety of the installation.
Step-by-Step Installation Procedure
Ensuring your helical piling foundation remains in optimal condition is crucial for the longevity of your home’s stability.
Unlike traditional foundations, helical pilings require unique maintenance to preserve their structural integrity.
Tips for Regular Check-Ups
These experts will look for signs of movement or stress and can make informed comparisons with traditional foundations to ensure the helical system is performing as expected.
Signs of Maintenance Needed

What factors influence the cost of helical piers for residential projects?
The cost of helical piers ranges from $1,750 to $3,000 per installed pier. Factors such as length, soil conditions, and additional materials affect the final price.
How do helical piers compare to traditional foundation methods in terms of durability and installation?
Compared to traditional methods like concrete piers, helical piers offer quicker installation with less soil disturbance. They are also noted for their durability in various soil conditions.
Can homeowners self-install helical piers, and what are the risks involved?
Self-installation of helical piers is not recommended due to the technical expertise required. Improper installation can lead to foundation failure and safety risks.
What is the typical number of helical piers required for a stable house foundation?
The typical spacing between helical piers is 5-7 feet. However, the total number needed varies based on the structure’s weight and soil stability.
What are the common disadvantages or limitations of using helical piles for foundations?
Despite their advantages, helical piles may be less suitable in rocky soils, and the initial investment is typically higher than some conventional methods.
In what scenarios are helical piers for decks considered the most suitable foundation solution?
Helical piers are most suitable for decks when the soil is unstable. They are also suitable when space is limited or when a rapid installation is required.
