Why you might need a Rotary Piling Rig
Rotary Bored Piling is a simple and efficient installation process.
Deep Bore Piling is easily achievable with correct casing and large tool diameters this means that very high capacity loads can be achieved with your Bored Piles.
Bore pile drilling is amenable to almost all ground conditions including rock drilling.
When using the Rotary Bored Pile drilling technique, you cause minimal ground disturbance and vibration which reduces risk to adjacent structures and buildings.
Rotary Bored Piles can be used to support any structure where the highest Pile load carrying capacity is required.
Larger diameters Bore Piles are easily achievable with the right Kelly Bar and Drilling buckets and can extend to greater Pile depths when compared with any other piling technique
Rotary bored piles can support heavy loads, overcome underground obstructions, penetrate ground too hard to bore using a CFA and drill piles with a cut-off level beneath the platform.
How Rotary Rigs work
Rotary bores drill to a designed depth, using an auger, drilling bucket or core barrels which support the pile through any unstable ground, and are reinforced with concrete once the required depth is reached
A rotary drilling rig or rotary drilling machine has a drilling rig rotary table, this rotary table is a mechanical device on a drilling rig that provides rotational force to the drill string to facilitate the process of drilling a borehole. Rotary speed is the number of times the rotary table makes one full revolution in one minute (rpm).
Rotary Bored Piling can offer higher power or torque than some CFA rigs and are able to overcome underground obstructions. Compared with other piling techniques LDP (Large Diameter Piling) can offer larger load capacities and be installed to greater depths.
Used Rotary Piling Rigs for sale
A popular make and model of Rotary Bore Pile Machine is the Bauer BG28, which has a telescopic Kelly bar which can expand to 3-5 times its original length.
You’ll also find Liebherr, Casagrande, Tescar, Soilmec, Bauer, IMT and many other Rotary Bore piling rigs for sale.

How Rotary Bored Piling works
Rotary bored piles are built by rotating an encasing into the field to support weak or granular soil, drilling tools such as augers and buckets are used to excavate the soils to form an open hole to the required depth. Once the bore has been thoroughly cleaned to desired depth, the pile of concrete is dispensed into the bore and the casing is removed leaving the finished pile. Where unstable ground conditions are present (commonly within made ground and in granular layers) a steel casing is used to provide temporary support and then withdrawn further along the process. This casing is either screwed in using the rig or vibrated into place. A reinforcing cage is then installed into the open bore and concrete is poured via a delivery tube or tremie.
Rotary Bored Piles are usually used for large industrial and commercial developments, transport infrastructure , public buildings and marine projects. Bored piles are often larger diameter than conventional continuous flight auger (CFA) piles and are used to support greater loads, overcome underground obstructions or penetrate ground too hard to bore using a continuous flight auger.
