High Capacity Foundations
 
When a tradional foundation can not be contructed becuase of soil limitations such in beach front properties and where controlling conservation regulations require low enviromental impact constuction. Ambrose Homes uses patented HELICAL PULLDOWN® Micropile technology to contruct high load capicity foundations in these sensitive areas. Chance's patented Helical Piers overcome the obstacles of traditional foundation methods for a growing number of applications.
 
  • Soil limitations: sand, wetlands, swamps, and unstable soil
  • Low enviromental impact is required
  • Confined construction area
  • Proven uniformed construction method for better site control
 
 
What is a HELICAL PULLDOWN® Micropile?
The HELICAL PULLDOWN® Micropile is a system for constructing a grout column around the shaft of a standard Helical Pier Foundation Systems pile.
To begin the process, a screw anchor is placed into the soil by applying torque to the shaft. The helical shape of the bearing plates creates a tremendous pulling force that keeps the anchor advancing downward into the soil. After the lead section with the helical plates penetrates the soil, a Lead Displacement Plate and Extension are bolted onto the shaft. Resuming torque on the assembled shaft advances the helical plates and pulls the displacement plate downward, forcing soil outward to create a cylindrical void around the shaft. From a reservoir at the surface, a flowable grout immediately fills this void, surrounding and encapsulating the shaft. Additional extensions and displacement plates are added until the helical bearing plates reach competent load-bearing soil. This displacement pile system does not require removing spoils from the site.
 

Benefits of this system include:

  • Resistance to buckling in weak surface soils
  • Stiffer pile (deflects less at a particular load)
  • Additional corrosion protection in aggressive soils

The HELICAL PULLDOWN® Micropile could be just the Deep Foundation Solution you’re looking for . . .put it to work on your next project.
