The A.B. Chance company invented the first earth anchor in 1912 and has been a leader in this field ever since. The system consists of a load-bearing helical pier that is constructed of a steel, helical shaped screw head attached to a high strength galvanized steel column.

The piers are screwed deep into the ground so that the helical shaped screw head is anchored deep into the soil. A portable high-torque hydraulic drive head is used to install the piers without disturbing the home or surrounding ground.

The load bearing capacity of the pier is based on the torque it takes to drive the pier. As the pier comes in contact with the bearing soil the helical plate begins to meet more resistance. Calculations based on the torque on the hydraulic head and the amount of resistance experienced by the pier flange determine the bearing capacity of the soil.

This has been engineered out and proven in thousands of load tests across the nation. The system can be installed with minimal disturbance to the surrounding property, eliminating need for large excavations and heavy trucks.

Once the A.B. Chance pier is driven into the ground to a depth capable of supporting a predetermined load with a safety factor, a patented footer bracket is attached to the top of the pier and the bottom of the footer. This transfers the loads of the home from the foundation walls down to the bottom of the helical pier which is in the underlying more stable soil and rock.

Once all the piers and brackets are installed, we will place hydraulic jacks on top of every pier to load test the pier and attempt to lift the footer and the foundation wall back toward their original position.

With all of mother natures factors involved, we cannot state the amount of lift which will occur, but there have been many homes in the state which have been able to completely close the cracks and return the home to its original position during construction.
