HELICAL PIER vs. CONCRETE PIER COMPARISON

Which would you rather have supporting your foundation?

HELICAL PILES

Helical
  • Clean installation with no spoils
  • No excavation
  • Installed below water table without casing
  • Can be loaded immediately after installation
  • No weather delays / No vibration / No noise
  • Load carried on helix bearing plates
  • Slender shaft reduces heave potential due to skin friction
  • Each pile is tested for capacity as it is installed by monitoring the torque values
  • Can be removed
  • A warranty you can count on

DRILLED CONCRETE PIERS

Drilled
  • Drill spoils
  • Must drill hole / Equipment / Time
  • Pier must be cased if water table is penetrated
  • Must wait for concrete to cure before loading
  • Weather delays
  • Typically depends on skin friction for bearing
  • Large surface area makes susceptible to heave due to skin friction
  • No way to test during installation
  • Cannot be removed
  • One (1) year warranty typical
