HELICAL PILE ASSOCIATION

The purpose of the Helical Pile Association is to advance Helical Pile technology within the engineering industry and provide homeowners with quality foundation repair solutions. The HPA provides in-depth resources to help those within the construction industry become more accustomed to helical products and the advantages they provide.

The Helical Pile Association is partnered with the largest manufacturer of helical products in the world, CHANCE Civil Construction. CHANCE Civil Construction Products  are based on 90 years of earth anchor research and development by the A.B. Chance Company of Hubbell Power Systems.

THE CHANCE HELICAL PILE

The CHANCE® Helical Pile is a segmented deep foundation system with helical bearing plates welded to a central shaft. Load is transferred from the shaft to the soil through helical bearing plates. As a result of their true helical shape, the helices do not auger into the soil but rather screw into it with minimal disturbance.

The first section, called the Lead Section, contains the helical plates. The Lead Section can consist of one to four helices.  If required, additional helices can be added with the use of Helical Extensions. Plain Extensions are then added until the Lead Section penetrates the bearing strata and the necessary or appropriate torque is achieved. The true helix geometry of each steel bearing plate minimizes soil disturbance during installation.  The helical pile foundation is preferred over driven piles, drilled shafts, grouted tendons, auger-cast piles, belled piers and other deep foundation systems for a number of compelling reasons:

HELICAL PILE ADVANTAGES:

 

• Fast installation and immediate loading.
• Pre-Engineered
• Eliminates high-mobilization costs associated with driven piles,  drilled shafts or auger cast piles.
• Instant torque-to-capacity feedback for production control.
• Easily modified in the field.
• No need for concrete to cure.
• Uses common construction equipment easily fitted with hydraulically-driven torque motors.
• Easy to use in limited access sites, high water tables and weak surface soils.
• No need to remove spoils.
• No casings required for flowable sands, soft clays or organic soils.
• Minimizes soil disturbance during installation.
• Installs in any weather.
• No vibrations.
• Environmentally friendly.
• Hot dipped galvanizing to ASTM A-153.
• ISO 9001 certification.

Helical Pile Foundation Systems are designed, tested, and proven for applications in expansive soils, high water tables, fill areas, and other areas where unstable soils require piling and anchoring.
