Because the micropile drilling occurs, a history is stored (ordinarily by the geotechnical engineer) of your thicknesses of the soil and rock layers in addition to the time required to penetrate the rock. According to the rock values provided while in the geotechnical report the engineer designing the micropiles has decided the depth into stable rock that should be necessary to carry the design loads (rigidity and compression) in friction of your pile on the edges with the drilled gap.
