Why the System Works
AB Chance® Helical Pier Foundation System offers technically superior
and cost effective
home repair solutions. Sinking foundations, cracks, bowed foundation walls, and uneven floors are commonly faced annually by a quarter of a million home owners. Homes and other structures settle on unstable soil settle when their foundations are subject to extreme moisture variations or lack of proper drainage. A shift in foundation may result in structural damage to your home, resulting in loss of your investments.
Repair concept is founded on the principle of turning a Helix (screw) pile into stable subsoil until the torque of applied indicates the necessary low capacity is achieved. Adjustable house foundation repair brackets are attached to the base of your foundation walls, connecting the piles to the foundation. The weight of your home is then transferred to the pile. In this process, the foundation walls and floors are repositioned and retained from further movement. By transferring the stress load, the soil holds 100% of the weight of your home. It is obvious when there is problems in the soil, there will be problems in your structure. Although there are upper repair procedures known as concrete stabilization, this does not address the issue of drainage or bad soil. In essence, the weight of the home must be taken off the bad soil and transferred to a composition which will hold the home. Dumping concrete or driving straight through (hydraulically driven) does not solve the problem and, in some cases, may increase the problems. This has been proven by mathematics and history over time. Remember, unless the ground was soil tested and drilled when the Contractor built, he initially thought the ground was solid.
With the AB Chance® Helical System, we can transfer the stress load to the repair procedure. The Helical System consists of a load bearing helical pier that is constructed of steel helical shaped plate which is attached to a galvanized high strength steel shaft. The piers are screwed into the ground so the helical shaped plate is anchored in the stable soil. A high torque hydraulically driven head is used to install the helical piers. As the pier comes into contact with the bearing soil, the helical plate becomes more and more resistant. Calculations based on both the torque of the hydraulically driven motor and the amount of resistance experienced by the pier determine the bearing capacity of the soil. This has been engineered and proven in thousands of test loads across the nation.
On top of the pier, a heavy duty L-shaped bracket is attached to the footer. This bracket transfers the load down the column to the helical plate, deep in the solid ground. Once in place, hydraulic jacks can be placed overtop the piers to lift the structure for repositioning. In most cases, we are able to close all cracks and return the structure back to original position. No other system can do this!!
