History of Helical Piers
Helical piers, also known as helical piles, helical anchors, or screw piles, have a fascinating history that dates back several centuries. The concept of helical piers emerged from various engineering and construction practices around the world.
Mid-19th Century
Helical foundations can be traced back to the mid-19th century. Alexander Mitchell, an Irish civil engineer, is often credited with the development of the screw-pile foundation. In 1833, he patented a screw-pile lighthouse foundation design, which was used for constructing lighthouses and other structures in soft, marshy ground or underwater sites
Early 20th Century
Throughout the 19th and early 20th centuries, screw piles became one of the most popular ways of constructing lighthouses, bridges, and piers in coastal regions, especially in places with poor soil conditions. These early helical piers were manually screwed into the ground using various methods, often with the help of human or animal labor.
1950s and 1960s
In the 1950s and 1960s, technological advancements led to the development of more efficient helical pier designs and installation methods. Engineers began using hydraulic machinery to install helical piers, making the process quicker and more reliable.
Helical piers started gaining traction in the civil engineering and construction industries during the late 20th century. Their applications expanded to include various types of structures such as buildings, bridges, communication towers, and transportation infrastructure.
Today
With advances in materials science, manufacturing techniques, and engineering design, helical piers have become a versatile and widely used foundation solution. Today, helical piers are commonly made of steel and are designed to withstand specific load requirements based on the project’s needs. They offer several advantages over traditional foundation methods, such as faster installation, reduced site disruption, lower environmental impact, and the ability to bear heavy loads in various soil conditions. These benefits have contributed to their growing popularity in the construction industry.
Today, helical piers continue to find applications in both residential and commercial construction projects. They are often used for underpinning existing structures, supporting foundations in environmentally sensitive areas, and stabilizing structures in regions prone to seismic activity or soil subsidence.
Foundation Support
Helical piers are used to support various structures in the oil and gas industry, such as equipment, tanks, pipelines, and modular buildings. They provide a stable foundation in areas with challenging soil conditions, including soft or loose soils, which may not be suitable for conventional foundation methods.
Soil Stabilization
In areas prone to erosion or landslides, helical piers are used to stabilize the soil and prevent ground movement. This is crucial for maintaining the safety and stability of oil and gas facilities and infrastructure.
Guy Wire Anchors
Helical piers are utilized to anchor guy wires and cables that support tall structures like drilling rigs, communication towers, and transmission lines. These anchors provide stability and reduce the risk of structural failure.
Pipeline Support
Helical piers are used to support and anchor pipelines, especially in areas with uneven or unstable terrain. They can be employed in both onshore and offshore pipeline projects to ensure the stability and integrity of the pipeline system.
BESS Projects
Helical piers are an increasingly popular choice in battery energy storage systems due to their numerous advantages, including ease of installation, load-bearing capacity, and adaptability to various soil conditions. As the demand for energy storage systems continues to grow, helical piers offer a reliable foundation solution for these crucial infrastructure projects.
Substations
Helical piers offer excellent load-bearing capacity, ensuring the stability of the substation structure even in soft or unstable soil conditions. Installing helical piers generates less noise and vibration compared to other foundation techniques, making them suitable for projects near residential areas or locations with noise restrictions. High-side breakers, low-side breakers, static masts, dead-end structures, control buildings, transformers, and HV cabinets are some of the various structures that can be supported by helical pier foundations.

Why Choose Helical Pier Foundations?
Helical piers offer several advantages over traditional concrete foundations, making them an increasingly popular choice for various construction projects.
Ease of Installation
Helical piers can be installed quickly and efficiently using hydraulic machinery, which significantly reduces construction time and labor costs. In contrast, concrete foundations require extensive excavation, formwork, and curing time, leading to a longer construction period.
Minimal Site Disturbance
Helical piers are screw-like steel shafts that are screwed into the ground, eliminating the need for large excavation and heavy equipment. This results in less disruption to the surrounding environment and a smaller construction footprint, making them ideal for projects in environmentally sensitive areas or sites with limited access.
Versatility
Helical piers can be installed in various soil conditions, including rocky or sandy soils, as well as in areas prone to high water tables. Their design allows them to bear different loads and adapt to a wide range of building types, making them suitable for residential, commercial, industrial, and infrastructure projects.
Immediate Load Capacity
Once installed, helical piers can immediately support the load of the structure, as they don’t require any curing time like concrete foundations. This can be especially beneficial for projects that have time constraints or where construction needs to proceed quickly.
Potential for Removal & Reuse
Unlike concrete foundations, helical piers can be removed and reused if necessary. This feature can be advantageous for temporary structures, such as modular buildings, or in situations where the foundation needs to be relocated.
Predictable Performance
Helical piers are designed and tested to meet specific load requirements, providing a more predictable foundation system. On the other hand, the quality and strength of concrete foundations can be influenced by various factors during pouring and curing, leading to potential inconsistencies.
Cost-Effectiveness
While the upfront cost of helical piers may be higher than that of concrete foundations, their ease of installation and reduced construction time often result in overall cost savings. Additionally, the reduced site disturbance and minimized environmental impact may lead to lower regulatory and permitting costs.
No Need for Concrete Mixing or Disposal
Concrete foundations require the mixing of cement, sand, and aggregates, which can be messy and labor-intensive. Helical piers eliminate the need for concrete, reducing waste and the associated environmental impact.
