Working steps

Perforating
The self-drilling bar, at the end of which a disposable drill bit is positioned, is used as
a drilling rod.
Conjunction
In order to reach the desired length, a second bar is connected by means
of a special sleeve
Injection
Tt the time of drilling, pressurised cement is injected inside the bar, which, as it escapes, creates a sheath around the bar useful for the bar/soil connection and to protect against corrosion.
End of the bar
A spreader plate is applied to the surface with a special nut or eyebolt as required.
