A deep foundation system creates support of building loads utilizing piers or piles to reach a deeper, more stable subsurface layer.
Helical piles are a factory-manufactured steel foundation system consisting of a central shaft with one or more helix-shaped bearing plates, commonly referred to as blades or flights, welded to the lead section. Extension shafts, with or without additional helix blades, are used to extend the pile to competent load-bearing soils and to achieve design depth and capacity. Brackets are used at the tops of the piles for attachment to structures, either for new construction or retrofit applications. Helical piles are advanced (screwed) into the ground with the application of torque.
A grouted micropile is a pile that is advanced through a grout reservoir at the surface. The lead displacement plate pushes soil outward and away from the central shaft and allows specialty micropile grout from the reservoir to flow by gravity into the void being created. The grout column surrounds the pile shaft to create a pile that is more resistant to buckling, and provides additional “frictional” capacity at the grout/soil interface.
No matter the job – we aren’t going to feel good about the hard work we’ve done until you’re happy. So we’ll do it right or make it right. That’s the GeoSupport promise.
At GeoSupport Systems, we focus on the value of doing whatever it takes to get the job done and “wow” our customers every step of the way.
A deep foundation system provides support for building loads utilizing piers or piles to reach a deeper, more stable subsurface layer. Deep foundation takes advantage of more stable strata and even bedrock to support the higher engineered loads required by compensating for shifting, incompetent soil near the surface.
GeoSupport has a proven track record of working with Commercial Developers, General Contractors, and Ag Installation companies, providing deep foundation solutions including Helical Piles and Piers and Grouted Micropiles.
