A helical pier owes its name to the helical plates welded to the pier shaft. These plates help to pull the pier into the soil during installation and provide anchoring strength as the weight of the foundation or structural element is transferred to the pier. Additional sections can be added to the pier until it reaches the necessary depth. Helical piers have a great deal of versatility for stabilizing and restoring foundations and masonry elements.
Advantages of helical piers:
- Year-round installation
- Fast, effective installation
- Stabilize light structures like decks or concrete stairs
- Can help lift settled foundations back to original level
