Rotary Drilling Rig KR125M

Product Introduction

The auger of KR125M CFA rig is drilled into the soil and or sand to the design depth in a single pass. Once the design depth/criteria has been achieved the auger containing the drilled material is then slowly removed as concrete or grout is pumped through the hollow stem. The concrete pressure and volume must be carefully controlled to construct a continuous pile without defects. Reinforcing steel is then lowered into the wet column of concrete.

The finished foundation element resists compressive, uplift, and lateral loads. Originally introduced to address saturated unstable ground conditions, modern CFA equipment represents a cost efficient foundation solution in most soil conditions.
