Features (*)

Eco-friendly piling method
During construction, a machine rotates the pile, and the blade on the edge performs digging that drives the pile into the ground like a wood-screw. So, low noise, low vibration, no waste soil and no ground pollution occur.

High reliability and quality
Large bearing capacity and pulling resistance capacity, thanks to the helical blade.

High applicable to severe construction conditions
Small area, nearby existing structure, requirement for small foundations.

Standardization method

TCVN and design guideline was already published

Benefits when using NS ECO-PILETM

  • Low noise and vibration
  • No surplus soil
  • No effects on ground water
  • Reduction of construction time and area
