High-pressure Injection Method (HDI)
Drilling method with complete soil replacement

High-pressure injection (HDI)

or also called jet grouting (DSV), differs between:

  • 1-fold HDI
  • 2-fold HDI
  • 3-fold HDI

With these three process techniques, a complete soil replacement is carried out and a concrete column is created at various depths. By adding air, a larger column diameter is achieved (2-fold / 3-fold HDI).
