A helical pile foundation, also known as a helical pier or screw pile, is a type of deep foundation system that is used to support structures or equipment. It consists of a steel shaft with helical plates or “flights” that are welded onto the shaft. These plates act as blades, allowing the pile to be screwed into the ground like a corkscrew.
Helical piles are often used in construction projects where the soil is unstable or has a low load-bearing capacity. They are particularly useful for sites with difficult access, limited space or in environmentally sensitive areas, as they can be installed quickly and with minimal disturbance to the surrounding soil.
Helical piles can be used for a variety of applications, including new construction, retrofitting existing structures, and for temporary or permanent installations. They can be used for a wide range of structures, such as buildings, bridges, towers, and solar panels.
The advantages of using helical pile foundations include their ability to be installed quickly, their resistance to corrosion and their adaptability to various soil conditions. They are also cost-effective and can be removed and reused if necessary.
At Frontiers, we often used metal helical piles for the foundation of a deck or small addition… our rationale is that they are more economical, as well as more durable. A no brainer!
