Both helical piers and push piers work to permanently stabilize and lift your foundation. Additionally, both of these steel pier systems make use of bedrock and load-bearing strata deep below the surface to provide stabilization for settling foundations. However, the main difference between these two pier systems comes from their overall designs. Helical piers get their name from the helical blades attached to their body. These blades allow the helical pier to “screw” into the ground, which evenly displaces dirt. Push piers simply use a straight rod design.
