PGA GEOPIER is the exclusive Philippine Licensee and authorized installer of GEOPIER? soil reinforcement system. The innovative GEOPIER ground improvement technology has been used worldwide since 1989. It has been proven to save construction time and cost, while providing a predictably reliable end product. The technology involves ramming aggregates in layers to prestress and prestrain the surrounding soil to mobilize and increase its bearing capacity. The stiffened GEOPIER? elements and the improved matrix soils provide a reinforced composite zone to support the structural loads.


GEOPIER soil reinforcement system,The Rammed Aggregate Pier? and Intermediate Foundation? Systems are used to:

  • Increase soil bearing capacity and support shallow footings on poor, marginal, or fair soils; alternate to deep foundations or massive overexcavation and replacement with short (3-8 meters long) GEOPIER aggregate columns.
  • Support floor slabs over unsuitable soils.
  • Reinforce soft foundation soils for transportation applications - embankment and retaining wall.
  • Stabilize landslides.
  • Support steel storage tanks.
  • Control soil liquefaction.
  • Provide tensile resistance using uplift anchors.
