Helical Pier Foundation System by Hubbell

The Hubbell CHANCE® Helical Pier Foundation System gives you the performance of concrete without the drawbacks and liabilities of driven piles and drilled shafts.

The helical pier foundation can be devised to resist or support any load or application. And it’s fast. It can be installed with lightweight construction equipment and loaded immediately. There’s no concrete curing time, and predefined capacities are predictable, putting you in control. The CHANCE® helical pier and tension anchor has become the deep foundation system of choice for architects, builders, contractors, engineers and geotechnical firms.

The CHANCE® Helical Pier Foundation System is perfect for a wide range of commercial, industrial, institutional and residential applications — from new homes and high-rise structures to sound walls, communication towers and bridges.

Here are just a few applications:

• New construction supporting foundation grade beams, column bases, compression, tension and concrete slabs
• Repairing failed or old foundations using time-tested engineering solutions
• Retrofit foundations in existing structures where new loads are being added or under existing concrete slab
• Permanent battered piers to take lateral loads, including wind and seismic 
• Machinery/equipment foundations for immediate loading with increased capacity 
• Wind and seismic loading applications such as sound walls, billboards, communication towers, etc

 The CHANCE® helical pier 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 these 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.
