The Soilmec SF range of dedicated CFA Rigs (Continuous Flight Auger) are self-erecting, high performing and hydraulically powered drilling rigs mounted on a crawler unit.
The multi-purpose SR range can also be configured to perform CFA technology.
CFA technology joins the advantages and versatility of the drilled pile applications. Continuous Flight Auger piles are performed with a partial soil removal and a lateral soil compression that increases the final load bearing capacity. The construction procedure consists of boring the soil by means of a continuous flight auger assembled on a central hollow pipe. On completion of boring operation, the auger is extracted while concrete is poured through the internal hollow pipe. When required, piles may be reinforced for their entire length with reinforcement cages inserted in the wet concrete.
