Auger cast piles
The continuous flight auger pile has experienced much development in recent years, they are widely used in building foundations. The principle consists in screwing into the ground a hollow stem auger over a length at least equal to the length of the pile to be made, then to extract the auger from the ground without rotating while simultaneously concrete is injected by means of the hollow stem of the auger.
Thanks to the vast improvement of drilling equipment, piles from 500 mm to 1000 mm in diameter can be made with depths up to 35 m.
