Stable Foundations LLC. is a Certified A.B. Chance Helical Pier provider and installer. A Certified Licensed Contractor. We only use the best product for you environment to last a lifetime of your home. The Helical Piers offered by other companies are not manufactured the same as the ones offered by A.B.Chance - The FIRST Helical Pile manufacturer ever. While others look the same they are not. The following are some examples of how a client may be deceived:

A. B. Chance products are Class B-1 hot-dipped galvanized in accordance with ASTM A153 (American Society for Testing and Materials). Competing manufacturers offer products as "galvanized" which in many cases means they were powder coated. Powder coating is NOT the same as hot-dipped galvanization and does not provide the same corrosion protection. Hot-dipped galvanization penetrates the steel surface and is not just a surface coat.

A. B. Chance Company extensions are constructed with a forged coupling. Some competing manufacturers weld oversized stock to form coupling joints to accommodate extensions.

A. B. Chance Company products are all welded in accordance with AWS (American Welding Society) standard D1.1. All A. B. Chance welders are certified to AWS standards. Competing companies state that their products are welded in accordance with D1.1 standards, but they fail to identify their workers as Certified Welders.

A. B. Chance Helical Piers and Anchors are manufactured to the International Standard Organization (ISO) 9001 Certificate No. 001136. This is a manufacturing standard which means that the material used to manufacture Chance Helical Piers and Anchors is NEW, UNUSED and traceable to the steel mill of origin. This is a building code requirement for deep foundations (Uniform Building Code and the International Building Code). Chance products carry a manufacture and heat treat number on each item and section. There are other manufacturers who do not comply with the code requirements because of the method of manufacture.

A. B. Chance Helical Piers have been thoroughly evaluated and approved for code compliance in the building industry as described in the following reports:
International Congress of Building Officials (ICBO), Engineering Report 5110.

Building Officials and Code Administrators (BOCA) Evaluation Service, Research Report 94-27.
Southern Building Code Congress International (SBCCI), Report No. 9504B.

Be sure to browse these files. Many companies reference these report numbers in their evaluation services and literature but they won't provide the documentation to back it up.

Helical Piers are true end-bearing piers. The weight of the structure is transferred to the helical plates. Helical Piers are installed independent of the structure and do not rely on the weight of the structure for installation. This prevents shaking or moving of the structure. Helical Piers are installed to a known capacity and a known competency of soil. This means that the helical pier can be installed with a factor of safety (most often 2 times the dead and live loads of the structure) and terminated in a soil strata or bedrock capable of supporting the load. Unfortunately, push piles cannot do this unless they are resting on rock.

In addition to the plan of repair, you will be provided a signed pier log, which needs to contain:

1.Project name and location
2.Name of contractor or responsible party with complete address and telephone number for contact.
3.Date and time of the installation.
4.Location and reference number of each pile.
5.Description of lead section and extensions installed at each pier location.
6.Overall depth of installation, as referenced from bottom of grade beam or footing.
7.Torque reading for the last three feet of installation, or the torque reading at the time of pier termination.
8.Any other relevant or pertinent information relating to the installation.
