Micropiles

Micropile can be made by boring or drilling holes in soil or rock, then micropile execution continue by inserting a reinforcing element adequate to the hole size. The micropiles are then grouted by backfilling the hole from the bottom, using cement mortar (grout). This type of micropile has a small bearing capacity, in accordance to micropile diameter, micropile length and the type of soil to which the micropile has to transfer the loads applied to the micropile itself.

Simultaneous drilling and grouting ensures that the grout is continuously placed over the full depth of the micropile, enabling grout to permeate the surrounding ground and increase skin friction. Rotary percussive installation ensures high rates of production and provides good directional stability if obstructions are encountered.
