What are helical piers?
Helical piers are used for two main reasons: to build foundations for various types of new construction projects and to raise sinking foundations. They get their name from the fact that the steel shaft resembles a helix. They’re sometimes referred to as “screw piles” because they resemble screws and they’re screwed deep into the soil to the required depth via a high torque motor. How far into the soil they go depends on a variety of factors including the building’s design load and the soil.
Why are helical piers good?
Their job is to take the weight of the structure and transfer it stable, load-bearing soil deep within the earth. Because they don’t require deep, expensive excavations they’re cost- effective and faster to install.
Why are screw piles called screw piles?
They’re sometimes referred to as “screw piles” because they resemble screws and they’re screwed deep into the soil to the required depth via a high torque motor. How far into the soil they go depends on a variety of factors including the building’s design load and the soil.
