  • Soil stabilization during excavation
  • Soil stabilization for slope stability
  • Anchor for tension pile
  • Anchor for tall structures foundation to ensure stability against overturning
  • Used as temporary anchor during erection of long span structures
  • Strengthening of existing structures such as dam
