Foundation piers are one method of rehabilitating a failing foundation. Piers provide a stabilization method used in both residential and commercial applications. Let's review the principle on how piers work.
Chance helical piers are constructed with a main shaft having helical bearing plates welded to it at certain intervals. The plates using a true helical shape do not auger into the soils but screw into the insertion point with minimal disruption to the soil..
The lead portion of the pier contains the helical plates. The lead section may contain up to four plates with the minimum number of plates being one. In certain instances additional plates can be installed with the use of helical extensions. Plain extensions are added as the helical pier penetrates the soil until the proper torque is achieved. The image in the lower right-hand corner shows the helical pier and extension.

Depicted above: is a typical stairstep crack. Mortar cracks may indicate a cause deeper then normal settling in the foundation.
| • | Time-proven, technically sound system |
| • | System and installation lower cost |
| • | Faster installation over other methods |
| • | Limited site excavation |
| • | Heavy equipment not required |
| • | Installs in limited-access areas |
| • | Use in new home construction to enhance foundation strength on sites with poor soil conditions |
| • | Patented Technology |
Below: depicts the repair of the stairstep crack and the result that can be achieved using the Chance helical peir foundation system.
