On one particular crucial challenge that was continually flooded resulting from unusually significant river concentrations ADF drilled and grouted micropiles by 24 feet of h2o.
The reinforcing may be possibly strong bar for open up gap or cased micropile applications or hollow bar for simultaneous drilling and grouting methods.
They are really a higher-overall performance and high-capacity deep foundation things. A micropile foundation may be used to help a variety of construction types.
