CFA augers are typically hollow, allowing concrete to be pumped through the center during installation—forming a continuous concrete column.
Characteristics of continuous flight augers:
Drilling buckets are designed for drilling through hard and compacted soils, as well as rocks. These augers feature a cylindrical bucket with cutting teeth at the base, which excavates and retains soil or rock as it rotates.
Characteristics of drilling buckets:
Hollow-stem augers are primarily used in environmental drilling and soil sampling applications. They feature a hollow center that allows for the collection of soil samples without removing the auger from the borehole.
Characteristics of hollow-stem augers:
Helical screw piles, also known as helical piers or anchors, are innovative auger-based foundation systems. They consist of helical plates or flights welded to a central shaft, and they are screwed into the ground to provide support for structures.
Characteristics of helical screw piles:
Rock augers are heavy-duty tools designed explicitly for drilling in hard rock formations. They feature reinforced cutting teeth and robust construction to withstand the demands of rock drilling.
Characteristics of rock augers:
Core barrels are specialized augers used for collecting intact soil or rock core samples. They consist of a hollow tube with cutting bits at the base and a mechanism for retaining the core sample inside the barrel.
Characteristics of core barrels:
