Helical ground screws are a type of foundation system used to support structures and secure them to the ground. They consist of large screws or helical plates that are mechanically rotated into the soil, creating a stable foundation for various applications.

The price of large, long helical screw piles can vary depending on several factors such as the length and diameter of the pile, the type of soil conditions, the load-bearing capacity required, and the specific project requirements.
