First projects with Ductile Iron Piles
The DYWIDAG Ductile Iron Pile is a driven pile system, utilising high strength ductile cast iron. Pile sections are connected together by a unique spigot and socket joint, which offers speed of connection together with a high degree of stiffness. The piles are installed in a quick succession using an Excavator with a Hydraulic Hammer, to both pitch and drive each pile section.
Manufactured as Ductile Cast Iron, also known as Spheroidal Graphite Cast Iron, the system is immensely strong and offers superior durability over conventional tubular steel piles.
Additional compressive strength is provided by the concreting or grouting of the bore, to form a composite pile.
Installed as an End-Bearing Pile (dry driven to a set, followed by concreting of the bore) or a Skin Friction Pile (simultaneous drive and grout, with an oversize shoe), the Ductile Iron Pile can accommodate a range of different ground conditions.
After being used mainly in Central Europe for a couple of years, the DYWIDAG Ductile Iron Pile has recently found applications on a variety of jobsites in Ireland, where the demand is currently high for piled foundations. Increasingly developers are looking to build on poor ground which they would previously have avoided due to the cost of a piling, also the demand for housing apartments on waterfronts has led to an increased requirement for piled foundations.
The DYWIDAG Ductile Iron Pile has been used for a range of piled foundations, from houses and apartment blocks to hotels and factory units. It also provides an effective pile in civil engineering applications including: pipeline support, bridge piers and wind turbines. The key benefit of the system is the rate of installation coupled with its flexibility for a range of ground conditions.
