Manufacturer

MacLean-Dixie manufactures the helix steel piers and equipment utilized by South Coast Helix Foundations, Inc.  MacLean-Dixie is a leading supplier of Helix Steel Foundation systems for use in residential, commercial, industrial and marine applications.  Their products include applications for tension, compression and stabilization in many different soils and regions.  All of the steel products can be traced back to the original mills, so the physical and chemical properites can be verified.

Composite Helical Pipe Pile (CHPP™)

Combines the technology of pipe pile with the helix steel piers to provide significantly greater load capacities.

Generally the CHPP are made of 8" DIA. Pipe which can be filled with concrete after installation. The helical pipe piles can resist both tension & compression loads along with larger resisting lateral loads.

The CHPP can also be customized using larger or smaller diameter pipe and more helices to better accommodate given coil conditions and load requirements for specific projects.

Load Range: 50-200 Kips
