A helical pile (also called a screw pile or helical pier) is made of steel.

The helix is the “thread.” As the shaft turns, the plate cuts and advances into the soil. The plates transfer weight into deeper, stable ground instead of relying on a shallow concrete pad that can heave with frost.

​

A hydraulic drive on an excavator turns the pile like a giant screw. The plates pull it down into stable soil. Once it hits the right depth and torque, it can carry the load of a deck, addition, or building.

 

•Coating: Helical Piles are hot dip galvanized so they last in wet Maine soil and resist rust.
 

•Top hardware: a steel cap or U-bracket (saddle) bolts or welds to the shaft so you can set a beam on it.
 

No waiting for concrete to cure, less mess, and they can go in through frost and poor surface soils.
