Deep Foundation Drilling: Why Hire Crane Borers?

20 November 2019

Perhaps a building is going up in an area that’s chock full of unfirm ground pockets. Also likely, perhaps the foundations of a building are expected to support a multi-storey structure. Lots of tall buildings are finding their way onto the Melbourne city skyline, and the soil conditions do vary wildly across the city, too. So crane borers do require deep drilling capabilities if they’re to overcome such structure-destabilizing issues, right?

Deep Foundation Drilling: A Destabilization Redressing Solution

There’s a shortage of flat, perfectly compacted soil. That’s a situation that occurs often in large cities. Left with loam and clay composites, construction engineers can’t assure a suitably anchored foundation level if those ground footings don’t sink deep enough into such “doughy” soil layers. And foundation work really is all about layers, about ground strata penetration. Basically, if that upper layer of clay and shale isn’t firm enough, then a structure’s foundations must dig deep, all the way below the loose stuff and into a firmer, denser band of soil. That, essentially, is why construction managers hire crane borers; they need a service that can expertly drill a diametrically precise hole through multiple layers of soil, even when that soil includes equipment clogging roots and deep-soil rocks.

Utilizing Structure-Supporting Piers and Piles

The provision of a properly configured block of edifice supporting concrete can be quite straightforward. Alternatively, often more likely, project obstacles accumulate so fast that the whole situation seems to fly in the face of logic. A basement is maybe going in above the foundations. Maybe the basement is out, but a number of ground-level support pillars are going in instead. To accommodate these specialized lower level supports and subterranean structural elements, special helical piles and piers are used to gain more traction below the soil. Only, without hire crane borers, the deep foundation openings collapse in upon themselves. Really, to maintain those deep openings, to keep the soil holes deep but narrow, a mobile boring service is the only way to really guarantee the integrity of all of the support points, from one end of the structure to the other.

So, what happens if a crane borer isn’t rented from a reliable hiring service? Sure, maybe the foundations do go in and the structure does climb high. But those support elements aren’t deep enough to properly anchor a tall building. And the soil type issues don’t help, either. With a strong gust, the energy absorbed by the top of the building is transferred downwards, where it’s expressed as a series of foundations cracks because the right crane hire borers weren’t employed to conduct a deep foundation drilling service.
