Sectional Auger Mini Piles
- 150mm to 450mm diameter flight sections.
- Has a solid or hollow stem.
Sectional Auger Mini Pile is formed by drilling into the ground with multiple flight sections installed to the designated depth. These rigs are very versatile and they easily allow for installation in restricted access zones.
When using these Sectional Auger Mini Piles, it is most common to bore the pile and then fill with concrete post extraction, however this does depend on the ground conditions.
Grout Injected Continuous Flight Auger
- Uses 250mm to 300mm diameter flight sections.
A Grout Injected Continuous Flight Auger is formed by drilling a continuous flight auger into the ground. The sides of the hole are supported at all times by the soil-filled auger, eliminating the need for temporary casing or bentonite slurry. Upon reaching the required depth, grout is then pumped down the hollow stem as the auger is steadily withdrawn.
The advantages to using a Grout Injected Continuous Flight Auger is they can be installed with very little vibrations or noise.
Steel Cased Bottom Driven Piles
- Uses 150mm to 300mm diameter flight sections
Unlike conventional driven piles, these piles are bottom driven so that all the energy is delivered directly to the pile toe, rather than in top driven piles that where all the energy dissipates down the shaft of the pile. This makes the system extremely efficient and enables high capacity piles to be installed using relatively small machines. With a selection of hammer weights, Steel Case Bottom Driven Piles piles can be constructed with working loads ranging from 5 tonnes to 85 tonnes.
