Product Description

CFA drilling equipment based on continuous flight auger drilling technique is mainly used in construction to create concrete piles. CFA piles continue the advantages of the driven piles and the bored piles, which are versatile and require no removal of soil. This drilling method enables the drilling equipment to excavate a wide variety of soils, dry or water-logged, loose or cohesive, and also to penetrate through low capacity, soft rock formation like tuff, loamy clays, limestone clays, limestone and sandstone etc. The maximum diameter of piling reaches 1.2 m and max. depth achieves 30 m, helping overcome problems formerly connected to project and execution of pilings.
