REVERSE CIRCULATION

RC drilling can drill and grout in one pass and can quickly and efficiently collect samples, while employing large rotary drills and air compression. Using large rigs and machinery, RC drilling routinely achieves depths of up to 500 meters.

The Hole Story

Typical RC Assembly

By blowing air down the annulus of the rod, the difference in pressure creates air lift to move water and cuttings up the inner tube. The dry cuttings travel around the inside of the cyclone until collected in sample bags for which detailed information is recorded for later analysis.
