The micropiles are small piles of circular section and small diameter. The micropiles are drilled on-site and can be arranged vertically or inclined. Operation of the micropilotaje is based on the transmission of load to the ground by side friction between the ground and the mortar of the micropile. Supporting field characteristics improve after carrying out micropilotaje due to the injection of cement at high pressure by filling possible holes in the ground. A micropilotaje may be the solution when the layers or superficial layers of terrain do not possess sufficient load capacity to absorb the loads transmitted by the structure to the ground.

The bearing capacity of the micropile is lower than of the piles. Execution of conventional piles are used in areas where it is not possible, either because of difficulty in access as other causes that prevent it. Current computers can perform fibreglass in any type of work, using micropiles of up to 300 mm diameter. After the reconsideration of the micropiles, is performs drilling by placing the machine right in the center of it. Then plumb the tower or pen and starts the drill through rotation. The micropiles are employed in new construction when solar and soil conditions so demand it.

The micropilotaje, by its method of construction, is suitable for any ground any that is its hardness. On the other hand, the micropiles drilling equipment can work in lots of small dimensions that are not accessible to the kellies. The micropiles are also used as system underpinning existing structures. The reduced dimensions of this type of Foundation drilling equipment make the underpinning is the more specific solution of this method that allows us to work inside buildings with small gauges and repair the defects of foundations, and can Pierce lugs and the existing structural elements and convey the efforts of these structures to deeper layers of the soil.
