Chance Helical Piers

Chance Helical Piers

Helical Piers contain Helices, or helical flights, that serve as end bearing plates for the weight of your home. These flights are welded to a central steel shaft. The helical shaft essentially acts as a screw that is rotated into the soil.

When using Helical Piers, the helices provide a large amount of surface area to resist or bear the weight of your home. Helical Piles are very effective in deeper soils where reaching bedrock is not possible. The helical flights will produce a force that translates into how much weight the entire Pile or Pier can carry.

The success of the Helical screw anchor system is based on decades of similar use of Chance anchors by electrical utilities. With over 100 years of structural engineering experience, the Chance Helical Underpinning System is unmatched. All system components are hot-dip galvanized to increase product life in aggressive soils, and are made in the United States.

Helical Piers vs. Pipe Piers

There is no true place to draw the line when using Helical or Pipe/Resistance Piers because there are many factors to consider. For instance, in some areas bedrock is further below the surface than others. In those cases, Helical Piers would be the best and most cost-effective solution. In other areas, bedrock is closer to the surface and easier to reach. In these instances, Resistance Piers would be recommended.

The only way to know which foundation repair application is the solution for your home would be to call an expert.
