High-pressure injection process (HDI) — drilling process with complete soil replacement

About the
high pressure injection drilling process

This drilling process is also known as jet blasting (DSV) and differs between 1x HDI, 2x HDI and 3x HDI.

In these 3 methods, soil is replaced or mixed and a concrete column or concrete body is created in various forms and functions at different depths. By adding air, a larger column diameter is achieved (2x/3x HDI).

This drilling process is used, among other things, to improve soil stability and to support foundations. The flushing medium is added above the rinse head, which emerges from the nozzle in the monitor at very high pressure to remove the soil material.
