Unique Drilling Auger & Continuous Flight Auger (CFA) adopt the high-carbon steel (Q345B, 16Mn, Q195-Q345, etc.) angle to keep the drilling strength and efficiency.

CFA are also known as auger cast piles, augered cast-in-place piles (ACIP), auger-pressure grout piles, drilled displacement piles and screw piles.

Continuous flight auger piles is a type of drilled foundation in which the pile is drilled to its final depth in one continuous process using a continuous flight auger.At the same time the augers are withdrawn from the hole, concrete or grout is placed by pumping the concrete/grout mix through the hollow center of the auger pipe to the base.
