Foundation Support Specialists offers three types of pier systems – push piers, slab piers, and helical piers. You might be wondering how these pier systems differ. Keep in mind, each pier system accomplishes the same overall goal: stabilizing your home and keeping it protected from settlement. However, each pier system is designed differently for use in different situations. Push piers use a simple long, straight, steel rod design that is inserted deep below the soil. Slab piers are specifically designed to be installed directly below a concrete slab. They share many design similarities with the push pier but differ in the way they are installed. Helical piers use a helix blade design to “screw” into the soil without disturbing it.
