For selected tasks, the temporarily cased pile could be a much more inexpensive Answer.

Substantial rotational torque and crowd power are employed to install Helical CIDH piles towards the expected depth. During installation, the Helical CIDH pile displaces and densifies the soil around the pile. No drilling spoils are produced or transported to the bottom area, building the process ideal for jobs with contaminated soil.

In the Karst type predicament where the upper rock levels are divided by unstable, in some cases zero blow count, substance the micropile will should be cased whilst drilling to the continual rock.
