Ground engineering drilling consists of various methods that include foundations, earthworks, environmental protection, hazard control and underground structures. These methods are primarily to stabilise loose, soft and often challenging ground conditions.
The past years, drilled casings have replaced many other conventional methods in difficult ground formations. High demands on productivity, drilling accuracy and ability to drill inclined piles for foundation work, makes casing advancement systems increasingly popular both for end bearing and friction piles. Atlas Copco casing advancement systems enable contractors to drill with high penetration rate, to required depth, in very challenging formations.
Foundation drilling is performed to install piles of large diameter (larger than typically 10") in the ground to make foundations for buildings, bridges and other structures. On the foundation drilling the casing advancement systems can be used in end bearing piles, where the installed casing can work as bearing support, or in friction piles where the casing is used only as an element to keep the hole open during the drill process.
