When Is Helical Pier Installation Used?
Foundations that are cracking or shifting may need the extra support provided by a helical pier support system or a push pier support system installed under the footing. These systems offer permanent support for areas that are shifting due to (1) expansive soils or (2) poor workmanship during the construction of the original foundation. These installations are warrantied for the life of the structure, and are a very cost-effective remedy for certain foundation problems.
What Are Helical Piers?
Helical piers, also known as anchors, piles or screw piles, work by transferring the structure’s weight to load-bearing soil. These round- or square-shaft steel piers are “threaded” into the ground to stabilize the foundations of residential, commercial and industrial structures. Helical piers:
- Are easy to install
- Eliminate extensive excavation work
- Require minimal soil disturbance
