    Drilling methods for deep foundations. The most common drilling methods in deep foundation are Kelly drilling, continuous flight auger drilling, full displacement drilling, double rotary drilling, drilling with hammer grab, reverse circulation air injection drilling and down-the-hole drilling. In the drilled cavity a multitude of products can be created, e.g. by filling with fresh sp.info CFA (auger cast) piles Keller North AmericaCFA piles are constructed by rotating a hollow stem continuous flight auger into the soil to a designed depth. Concrete or grout is pumped through the hollow stem, maintaining static head pressure, to fill the cylindrical cavity created as the auger is slowly removed. The grout pressure and volume must be carefully controlled to construct a sp.info Practical Considerations in the Selection and use of May 07, 2012 · The use of continuous flight auger (CFA) and drilled displacement (DD) piles in the U.S. market has increased significantly in recent years. This paper describes some of the advantages and limitations of these drilling systems compared to other deep foundation systems.sp.info Continuous Flight Auger Cfa Piling Balfour Beattyadvantages of fixed piles with the versatility of application of drilled piles. Continuous flight auger and drilled displacement piles. Continuous flight auger (cfa) piles are drilled foundations in which the pile is drilled.
