Liquefaction Mitigation

Optimizing Investments Below the Ground!

 

Impact® Pier ... a Proven Rammed Aggregate Pier® Foundation System!

 

The Impact® pier system is a great improvement on the proven and successful Geopier soil reinforcement method. With over ten years of proven performance in California, Farrell Design-Build is committed to providing its customers cost savings using the Impact® pier system, a full displacement Rammed aggregate pier® construction method.

Impact® Pier Description: The Impact® Pier system uses vertically forced displacement technology to densify and reinforce loose and weak soil below groundwater, including loose sand, silt, clay, mixed soil layers, and uncontrolled fill. With construction that utilizes vertical vibratory impact ramming, the Impact pier exhibits higher strength and stiffness than traditional vibrated stone columns. Impact vibratory ramming results:
1- Densify clean SP sands and
2- Reinforce silty sand, silt and clay

Impact® Pier Applications: Impact pier construction is best in high groundwater sand and silt sites that need to support heavy foundation loads and the following:

  • stiffen loose/soft soil for footing support
  • liquefaction control = reinforce + densify
  • soil treatment to depths of 45 feet plus
  • Water treatment plants on loose soil
  • Fuel tanks and Water tanks on soft soil
  • Moderate to heavy building loads

  LIQUEFACTION MITIGATION Densify Sand Zones to 50 feet. Increase shear resistance of silty sand & clayey sand. Increase softening resistance of lean clays and low plasticity silts.
  BUILDING FOUNDATION SUPPORT Unmatched aggregate pier stiffness!
Increase bearing capacity & reduce settlement of saturated fill and loose soil.
  FUEL and WATER TANK SUPPORT Improve soil and fill to create uniform bearing platform for tanks.
  SEISMIC UPLIFT RESISTANCE Highly efficient uplift resistance per foot of depth, up to 100 kips ultimate.
  EMBANKMENT SUPPORT
MSE WALL AND FILL SUPPORT
SLOPE STABILIZATION TO 50 FEET
 

The Impact® Pier ADVANTAGE:
  RAMMED. Vertically ramming thin lifts of rock is the key to high strength and stiffness.
  STRENGTH. Heavy crowd + vibratory hammering results in high load capacity.
  STIFFNESS. Vertical ramming results in high pier stiffness = excellent settlement control.
  PROVEN. Thousands of structures supported – proven experience = performance & reliability.
  ECONOMICAL. Results in 20% to 50% cost savings compared to traditional deep pile foundations.
  FAST. Rapid installation process means shorter construction schedules.
