The grout transfers the load by way of friction with the reinforcement to the bottom during the micropile bond zone within a manner much like that of floor anchors. Because of the compact pile diameter, any stop-bearing contribution in micropiles usually is neglected. The grout/ground bond toughness achieved is motivated principally by the ground kind and grouting approach employed, i.e., stress grouting or gravity feed. The function from the drilling approach also is influential, Though much less effectively quantified.
