Piling

Building a good foundation is essential in any construction project. But tight deadlines and complicated urban environments set challenges to contractors working in the field.

At Mincon we work hard to ensure that each of your foundation projects is finished safely, on time and on budget. This is possible with our DTH drill string consumables offering class-leading performance and safety in complex environments.

Our patented Spiral Flush air control technology makes drilling in the overburden and tight urban spaces safe, and the wide variety of our casing systems can be delivered in sizes from 114 mm (4.5”) to 1,524 mm (60”) with the option of having custom project-specific systems manufactured in our own factory.

When building foundations of a construction, like a building or a bridge, impact and vibration driven piles work well in soft overburden. Bored piles (”Kelly piles”) are also convenient when building large-diameter piles in easy overburden. But the problems start if these types of piles hit any rocky layers. Impact and vibration driven piles simply stop and the progress of bored piles slows down significantly. And boring into bedrock becomes painfully slow.

On the other hand, when using down-the-hole or DTH tooling, piles are drilled with a DTH hammer which literally goes into the hole and uses high-pressure air as its power source. The air moves a piston up and down which, in turn, strikes a pilot bit against the rock. This high frequency hammering with rotating movement crushes any rocks that come in the way.

The same high-pressure air is then used to flush the cuttings up from the hole. This is a continuous process that allows fast penetration into overburden and bedrock. Also, as the hammer is always close to the action at the bottom of the hole – unlike in top hammer design – the drilling is efficient even in deep holes. DTH drilling is also suitable for large-diameter drilling up to diameters of 1,524 mm (60”). All these features mean that the building process is predictable. You know already beforehand how much it costs to drill DTH piles. It also means reliability that the drilling progresses, no matter what is hidden underground. And when all can be done with the same drilling rig with Mincon’s efficient DTH hammers and Spiral Flush pilots, it all comes down to speed. You get things done fast.

All Mincon piling tools can be delivered in a wide range of sizes, from 114 mm (4.5”) to 1,524 mm (60”). They also use our patented Spiral Flush technology – a market-leading airflow control system that makes it safe to drill with compressed air in sensitive ground conditions.

Our experienced project engineers are here to help you to decide the most cost-effective piling solution, whether it includes our stock options or something customized for your project.
