PROBLEM:  This two story apartment building had foundation wall settlements up to 14″ due to loose fill along with organic silt and loose virgin sand soils.

SOLUTION: We installed fourteen resistance piers with a design load of 22 kips and test load of 44 kips.  The piers were installed through fills and very loose sands to 20′ – 25′ depths.

RESULT: The foundation wall was supported and stabilized with lifts up to 11-1/2″. Any further settlement along the foundation wall was stopped.

Atlas Resistance Piers are commonly used to stop and reverse foundation settlement.  Typical working loads for 2-7/8″ to 4-1/2″ diameter piers range from 30 to 55 kips.

Atlas Resistance Pier Capabilities include:

  • Design loads up to 55 kips (ultimate 110 kips)
  • Limited access needed for installations: 3-1/2′ x 3-1/2′ opening and only 7′ of headroom
  • End bearing 2-7/8″ to 4-1/2″ dual wall or single wall pipe (minimum N-value of 40-50 required)

Atlas Piers are the most rugged H.D. pier available. Also, Atlas geotechnical engineers are on call to provide preliminary design for every project.
