Augered pilingBored piles
Open hole augered piles→
Quiet, low-vibration bored piles for cohesive ground, from light loads to heavy ones, on a rig sized to your site.
How it works
An open hole augered (OHA) pile is drilled with a rotary auger, which brings the soil up as it goes. Once the bore reaches the design depth, reinforcement is placed and the hole is filled with concrete. In stable, cohesive ground the bore stays open on its own while this happens.
Our augering rigs range from 3.5 tonnes up to 29 tonnes, and we allocate them to suit the demands of each project. The same rigs install retaining wall piles as well as standard bearing piles.
When it’s used
OHA piles are typically considered for cohesive soils such as firm to stiff clays, soils prone to ground heave, and ground with a low water table.
Advantages
- A rig sized to suit your site and your loads
- Rotary augering causes minimal vibration, so it’s ideal next to buildings and underground services
- Low noise
- Easily adapted for down-the-hole hammer drilling to anchor into firm strata such as mudstone or sandstone
- Can be designed to overcome the adverse effects of ground heave
