SFA (Sectional Flight Auger) piling is the process in which piles are drilled into the ground, followed by concrete pouring and steel cage installation. This technique is suitable for carrying out construction work in hard-to-reach areas where access and headroom are limited. It involves the addition and removal of augers during pile construction, helping to attain the required depth.

How Is SFA Piling Done?

SFA piling is a type of replacement piling which involves soil extraction before the pumping of liquid concrete under pressure. A hollow stemmed vertical screw or auger is used for forming the initial piles by boring into the earth to a certain level of required depth. Once the boring has been done, liquid concrete is poured in. Then, a steel cage is installed for forming the pile, and the auger is removed.
