FAQS
When should a contractor use a casing oscillator instead of a vibratory hammer?
Casing oscillators are often preferred when vibration must be minimized or when precise casing installation is required. They are commonly used in urban environments, near existing structures, and on projects with sensitive ground conditions.
What are the advantages of fully cased drilling methods?
Fully cased drilling helps stabilize the borehole, reduce the risk of collapse, improve drilling accuracy, and provide better control in challenging soil conditions.
Can Leffer casing oscillators improve borehole stability?
Yes. By advancing casing as drilling progresses, Leffer systems help maintain borehole integrity and support successful foundation installation in unstable ground conditions.
What soil conditions require casing installation?
Casing is commonly used in loose sands, gravels, collapsing soils, groundwater conditions, and other environments where borehole stability is a concern.
What is the difference between a casing rotator and a casing oscillator?
A casing rotator continuously rotates the casing during installation, while an oscillator moves the casing back and forth in an oscillating motion. Both systems help advance casing but are selected based on project requirements and ground conditions.
