Ductile iron piles have been used in Austria and increasingly in many countries since the 1980s as an economic, yet technically very high-quality deep foundation method. They are used as foundation elements in building construction, civil engineering, industrial construction, pipeline construction, bridge construction and for special applications. The ductile iron full displacement pole, which is inserted into the ground by ramming, effectively directs the forces from the structure into the ground.
Regulations on design, quality assurance, statics and installation are currently specified in Austria in ÖNORM B 2567. For the first time they were regulated in the ONR 22567 from 1999, which was then completely revised in 2012 on the basis of the Eurocode and published as ÖNORM B 2567. This Austrian standard has aroused great international interest, which is why it is also available in an English-language version.
In international use in Pakistan
Tiroler Rohre GmbH has been producing and supplying ductile cast iron pile systems all over the world for more than 30 years. Based on his experience, the company from Hall in Tirol was able to land a major deep start-up project in Pakistan. The client was the "Frontier Works Organization", the technology and science division of the Pakistani army.
