What Are Helical Piers?

• Definition: Helical piers, also called screw piles, are strong steel rods with spiral plates that help support buildings. They act like big screws and go deep into the ground to keep things steady.
• Parts:
  • Shaft: This is the main long part that goes into the ground.
  • Helical Plates: These are the spiral plates on the shaft that twist into the soil to hold it firm.
