Bar using a Hollow Micropiles are drilled in to the earth employing a sacrificial drill/grout tip although pressure grout is poured down the hollow bar
Micropiles could possibly be utilized in Just about any soil affliction, and load is obtained by bond pressure in between the grout along with the encompassing soils.
