Construction and Geotechnical Solutions

For advanced geotechnical drilling, Mincon’s ring-bit casing advancing systems offer solutions for a variety of construction techniques, including foundation drilling, pipe pile-walls, forepoling, well drilling, and anchoring.

Mincon ring-bit systems use our patented Spiral Flush air-control technology to avoid damage or disruption in complex ground conditions or existing foundations, thus leading to safer drilling.

In large-diameter drilling applications energy transfer to the ground is significant, but Mincon’s DTH hammers have a high-frequency design that lets them operate above the nominal frequency of the ground. This mitigates excess ground vibration by cycling hammers above the natural harmonic frequency of the ground.

All Mincon geotechnical products are manufactured to exacting tolerances using the very best materials and tungsten carbide buttons, ensuring excellent service life.

Our geotechnical drilling solutions are backed up by a global service footprint and highly experienced consultants with in-depth knowledge of Mincon products and cutting-edge geotechnical techniques.​​

Spiral Flush design results in no pressure to the ground, no air leakages, and no over drilling!

Spiral Flush Design

  • Flushing channels are crosswise to the drilling direction
  • Back flush creates vacuum to the pilot bit face area
  • Air channels are above the ring bit cutting edge

Conventional DTH Drilling

Conventional DTH drilling has two problem areas:

  • Pressurised air over drills material. Over drilling removes more material than anticipated changing ground’s original characteristics hazarding nearby structures.
  • Air that is blown forward travels long distances in loose ground or soft clay. This can cause severe damages in nearby buildings and structures.

As a result, the use of conventional DTH drilling is limited already in several city centers, shorelines and other sensitive areas around the world.
