Driven Ductile Iron Piles

A simple, fast and highly effective low-vibration-driven pile system utilizing high-strength ductile iron.

Ductile Iron Piles are a simple, fast and highly effective low-vibration-driven pile system utilizing high-strength ductile iron. Modular pile sections are connected by a proprietary Plug & Drive system, eliminating the need for welding and splicing while providing a section at the connection which is more than twice that of the pipe pile section, resulting in superior dimensional and driving stability and performance.
With the use of a relatively small excavator fitted with a high frequency hydraulic hammer, piles are installed by driving the pile sections in quick succession for fast and easy installation with minimal vibrations. Ductile Iron Piles can be designed and installed for end bearing and friction resistance.

End Bearing

In an end-bearing installation, an end cap or driving point is fitted on the end of the DIP lead section and successive sections are added as the Ductile Iron Pile is installed to transfer foundation
loads through compressible soils or to fill down to soil that is more competent, or to bedrock. The pile can be further filled with grout or concrete, and additional central bars can be added as needed for additional capacity.

Friction Resistance

Ductile Iron Piles for friction are installed with an oversized conical grout point at the pile base. As the pile is driven, sand-cement grout is pumped through the pipe sections and exits through grout ports within the conical grouting point to fill the void space created by driving the oversized cap. This process encapsulates the pile in grout and forms the basis for the grouted bond zone within the surrounding competent soil to achieve the design capacity.

Ductile Iron Piles are often a cost-effective and rapid alternative to traditional deep foundations. The system excels in supporting high-capacity foundations in constrained sites or urban settings where tight access and low vibration requirements influence foundation selection. The Ductile Iron Pile results in zero waste on site, as each cutoff is able to be used as a starter section for the next pile.

Ductile Iron Piles
Friction DIP elements are installed using 5m bell-spigot sections and a special driving hammer with a wet driving shank where grout is pumped continuously through the pile to a tremi-grout head at the base. A high capacity friction system results from the installation and central bar can be added to increase tensile or compressive capacity as needed.

Friction DIP elements can be installed in many soil types with various diameters and to practically any depth with full displacement and impact energy improving the surrounding soils for high frictional capacity, with more versatility than helical piles, and less cost than micropiles.

End-Bearing DIP elements are installed using 5m bell-spigot sections and a special driving hammer with a dry driving shank and a pointed or flat tip. A high capacity end bearing pile system results from the installation and concrete/grout central bar can be added to the inside of the pile to increase compressive capacity as needed.

With many different sizes and combinations, End Bearing DIP elements can be installed in many soil types to practically any depth with full displacement and impact energy improving the surrounding soils and reaching end bearing while driving the tip into the end bearing soils to maximize both structural and geotechnical capacity. The End Bearing DIP is superior to helical piless particularly in situations where you are transitioning quickly from very poor to very hard soils.
