Piling Systems

Piling Systems are a Cost-Effective, Versatile Solution for Supporting Heavily Loaded Foundations

Why Use Piling Systems?

In some cases, a deep foundation is the best solution. Piling systems are very versatile in that they are available in many shapes and sizes, and are typically pre-fabricated or cast in place, depending on the piling system type. 

Piling systems allow for rapid construction, and are a clean, efficient method for creating sound foundations.

1. Driven Ductile Iron Piles

Geosolv Driven 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.

 

Geosolv Micropile DIPS end

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 piles particularly in situations where you are transitioning quickly from very poor to very hard soils.

2. ​Helical Screw Piles

Helical Screw Piles

Helical screw piles are installed using round pipe or square shaft lead sections (of various diameters/sizes) with one or more helical flights torqued into the ground with pile extensions added to increase length. Helical screw piles can also be gravity grouted using displacement plates to add shaft capacity, with the majority of the load is handled through resistance on the helices. 

Helical screw piles can be installed for tensile and compressive capacity in many soil types and installation torque during installation is correlated to pile capacity using industry tested correlations.

3. Drilled Micropiles

Drilled Micropiles by Geosolv

Hollow Bar Micropiles are drilled into the ground using a sacrificial drill/grout tip while pressurized grout is pumped down the hollow bar while drilling. Micropiles can be used for practically any soil condition and load is gained through bond stress between the grout and the surrounding soils. 

Micropiles have the advantage of being the one piling system that has the best chance of penetrating obstructions during installation. A wide variety of drilling tips are available for different soil conditions.
