Technical Bulletin – Vibrations of Helical Piles

Vibrations of Helical Piles

This Technical Bulletin examines the vibration characteristics associated with the installation and performance of helical piles. It explains that, unlike driven piles, helical piles are installed using a rotational method that significantly reduces ground disturbance and vibration levels. As a result, they are well-suited for projects near existing structures, sensitive equipment, or vibration-restricted environments.

The bulletin also outlines factors that can influence vibration levels, including soil conditions, installation torque, equipment used, and proximity to adjacent structures. It reinforces that helical pile installation typically produces minimal, low-amplitude vibrations, helping reduce the risk of structural impact or ground settlement. Overall, the document highlights helical piles as a reliable solution when vibration control is a key project requirement.
