For decades, Helical has been revolutionizing the ground improvement and geotechnical construction industry in the Northeast.

Unique foundations need unique solutions.

Helical specializes in creating customized foundations for even the most complex ground construction challenges.

While we’re constantly adapting our technologies to new ground improvement techniques with a team of geotechnical engineers and construction managers, these are the common geotechnical challenges we’re prepared to solve today:


  • Unsuitable Geotechnical Conditions
    • Deep Fill
    • Peat and Organics
    • Soft Ground
    • Shallow Groundwater
    • Excessive Settlement
    • Insufficient Soil Bearing Capacity
    • Soil Liquefaction
  • Heavy Foundation Loads
  • Compression Load Resistance
  • Uplift or Tension Load Resistance
  • Limited Access Construction
  • Low Vibration Construction
  • Work Adjacent to Existing Structures
  • Excavation Adjacent to Existing Structures
  • Deep Excavations
  • Basement Expansions
  • Reinforced Slopes
  • Slope Stabilization


  • Settling/Sinking Foundations or Slabs
  • Unstable Foundations or Slabs
  • Adding Loads to Existing Structures
