Micro pile

Slope reinforcement
and stabilization

The micro pile slope strengthening process typically involves drilling an injection boring rod into the slope. Grout is pumped through the rod and through the drill bit at a maximum of 300 psi. The drill bit has multiple grout ports and cuts into the soil formation as the drill bit is advanced into the soil. The drill bit also tends to "wobble" over sizing the drill hole.

The end result of this single pass drilling and injection process is the construction of a micro pile consisting of a reinforced and treated soil mass. Because of the drill bit wobble a highly irregular hole is created with numerous ridges and depressions. In addition, the grout permeates into the surrounding soil matrix strengthening the soil.
