The Stabilizor® is a unique and exceptionally strong helical piling system (helical pier, helical support) designed and manufactured by Atlantic Foundation & Repair.
Featuring the company’s patented articulating bracket, this powerful system gently lifts and permanently supports settled houses and other structures. It is also an excellent remedy for soil problems and can be used to create a firm foundation for new home construction.
The Stabilizor® is engineered to be free of the weaknesses of other foundation systems. For example, systems that use thin shaft anchors or piers are subject to “kinking,” or buckling, if the weight of the house structure exceeds the capacity of the anchors. Push pier systems, which repeatedly lift a structure while using its weight to push piers into the ground, can cause “walkout.” This occurs when a section that is being lifted moves away from the rest of the structure.
By contrast, The Stabilizor® lifts a house only when setting it back in place.
It is the system’s patented articulating bracket that sets The Stabilizor® apart. The bracket is designed to pivot during the lifting and stabilization process. As a result, it remains aligned with the house’s foundation, preventing damage to the pile, the bracket itself and the foundation. Without this “give,” the results can be induced foundation failure or bending failure points.
Helical steel piles may not appear to be different. At first look the shape of the pile may not appear to make a difference. Even though the amount of steel in The Stabilizor® , The Stabilizor® 2875 and others may be the same, the loads they are capable of carrying is vastly different. The load capacity of helical piles in soil is dependent on the soil, and building codes recognize this fact. The Stabilizor® is 2 to 2.5 times stronger than competitive systems.
When used for foundation repair where there are asymmetric forces, the differences are astounding, The Stabilizor® will safely carry 4 times the load of square piers and about 1.5 times the load of The Stabilizor® 2875.
When tested in typical foundation repair applications, the following capacities were achieved:
1.5 in. square steel 48,000 lb
Components of The Stabilizor® can be used in tension applications such as tiebacks or uplift restraints. The Stabilizor® pile can safely be used in tension loading of 50,000 pounds. Load capacities of the anchor can be predicted as with any earth anchor, dead-man anchor or helical anchor.
When brackets and piles components are used in tension applications, additional nuts must be installed above and below the pipe adapter and bracket body “ears,” and the pier adapter field must be welded or bolted to the pile.
In new construction applications where uplift is a concern, provisions must be made for attachment of the pier cap to The Stabilizor® pile.
When The Stabilizor® is used to remedy foundation failures in existing homes, the installation works like this:
The Stabilizor® has repaired the foundation and closed the cracks.
In new home construction, The Stabilizor® is an ideal solution when the foundation requires additional structural support or in cases where engineered foundations are required.
Here’s how the installation works:
In choosing a foundation repair system, it pays to compare The Stabilizor® helical pile to other piers. The Stabilizor® helical pile and extension have an outside diameter of 3.5 inches. It’s this diameter that makes a difference.
Typically, piers are installed to depths ranging from 7 feet to 50 feet. At these lengths, diameter determines strength: a larger diameter provides more area to disperse the force pushing down on it. In fact, the piles used in The Stabilizor® are 1.5 to 4 times stronger than piers used in other foundation repair systems. The Stabilizor® meets the requirements of the American Institute of Steel Construction for pile applications, where other suppliers’ piles may not.
Allowable load is 38,000 lbs

No Kinking Kinking often occurs with support systems that use thin shaft anchors or piers. If the weight of the house exceeds the capacity of the anchors, the shaft will buckle, or kink, and fail.
Push pier systems can also fail if soil conditions change because they use friction to support a structure’s weight. If a repair is done when soil is dry and soil conditions change, piers will slip because of the change in friction.
“Walkout” can occur with push pier systems that lift a house and then use its weight to push the pier into the ground—a process that can be repeated many times and may cause a section that is being lifted to move away, or “walkout,” from the rest of the house. The Stabilizor® lifts a house only when setting it back in place.
