Capacities change depending on the micropile dimensions and subsurface profile. Installation could be obtained by rotary drilling, augering, driven or vibrating tooling.
Inevitably we chose to jet the pile in terms of it might go and after that driving it (pneumatic hammer) to idea elevation or refusal (whichever came first). For the reason that the material was in truth jetted, it created the driving easier and we obtained tip elevation usually.
