Standard square shaft helical piles can be installed using compact equipment, such as a skid-steer loader, or excavator with a hydraulic drive head. This approach not only speeds up the process of installation but also eliminates the need for extensive ground preparation. Operators play a vital role in ensuring the piles are placed in a straight line, using both visual cues as well as assistance from ground crews.

One of the key elements of helical pile installation is to achieve the desired load capacity. This is when the relationship between the installation torque as well as load capacities becomes crucial. The most modern torque gauges, such as the Chance Digital Torque Indicator, are a key component in this process by providing precise measurements and eliminating the uncertainty associated with hydraulic pressure estimations.
The speed at which the installation takes place is vital, generally ranging between 8 and 16 RPM. This controlled speed will ensure that the pile moves approximately 3 inches every revolution in accordance to the helical plate's pitch. If the pile doesn't advance according to plan, adjustments such as raising downward thrust or adding larger plates for helicals are made to prevent spinning out like a screw stripping its threads.
Screw piles, sometimes referred to as screw-piles, screw piers, screw anchors, screw foundations, ground screws, helical piles, helical piers, or helical anchors are a steel screw-in piling and ground anchoring system used for building deep foundations. Screw piles are typically manufactured from high-strength steel[1] using varying sizes of tubular hollow sections for the pile or anchors shaft.
The pile shaft transfers a structure's load into the pile. Helical steel plates are welded to the pile shaft in accordance with the intended ground conditions. Helices can be press-formed to a specified pitch or simply consist of flat plates welded at a specified pitch to the pile's shaft. The number of helices, their diameters and position on the pile shaft as well as steel plate thickness are all determined by a combination of:

Helical piles are also excellent in sustainability, which is an important aspect in modern construction practices. Since they cause minimal disturbance to the area and don't need concrete to construct, their impact on the environment is much less than foundations constructed with traditional materials. Furthermore, they are typically constructed from recycled steel and their ability to be removed allows them to be reused, improving their eco-friendly appearance.
Another notable advantage of helical piles is their capacity for load-bearing immediately after their installation. This immediate load transfer capability permits construction to begin without a delay, which is in distinct contrast to the lengthy waiting periods for concrete foundations. It also provides a distinct advantage in emergency situations or in the case of unstable structures which require immediate stabilization.
Helical piles, sometimes referred by the name of screw piles are one type of foundation that is deep and consists of one central shaft and some or all of the blades that resemble helix shapes. This design enables the screw to be inserted in the soil, creating solid and secure foundation for various types of structures. The origins of the helical piles are in the 19th century innovations from Irish engineer Alexander Mitchell, helical piles have evolved and are now at the forefront of current foundation technology.
One of the most notable characteristics of helical piles is their ease and speed of installation. In contrast to traditional concrete foundations which require significant excavation and curing times Helical piles are able to be installed quickly using hydraulic machinery. This not only accelerates the construction process but reduces their impact on surrounding environment. The lack of large excavations makes them especially advantageous in urban settings or in environmentally sensitive areas where preserving the natural landscape is paramount.
In addition to their core benefits, helical piles have a variety of other advantages that make them more prominent in contemporary construction. These include:
These additional advantages, when combined with their primary advantages are what are what make Helical piles an extremely versatile and reliable foundation choice for a range types of projects.
In the constantly evolving construction industry, helical piles have emerged as a nefarious gem providing strengths that are changing the construction industry. This article focuses on the advantages unique to the installation of helical piles, and explains why they are increasingly favored in modern construction projects.
Helical piles also referred to by the name of screw piles. They are a deep foundation that is distinguished by its spiral-shaped plates, which are connected to a shaft of steel centrally. This design is innovative and allows for quick and efficient installation, as the piles are actually installed to the earth. This method stands in stark contrast to conventional foundation techniques, offering distinct benefits.
Building on the foundational strengths of helical piles and their usage in construction projects provides a number of specific advantages. They can be described as follows:
These points highlight the multifaceted advantages of making use of Helical piles, emphasizing their role in improving efficiency, sustainability and cost-effectiveness of construction.
