All structures rely on a solid foundation, and an in-depth understanding of what lies beneath the earth’s surface — whether it’s rock or soil — is essential. Such insight helps inform decisions on foundation types and materials that are best suited for a project.
Understanding a Structure’s Foundation Needs
A key step during a project’s inception is a site evaluation overseen by a geotechnical engineering team to consider the site’s subsurface conditions, strength characteristics and physical properties. That’s because not all foundation types are suitable for all locations. Working closely with a project’s structural engineers, the geotechnical team may recommend shallow foundations or deep foundations such as drilled shafts, micropiles, drilled piles or helical piles. Helical piles are prefabricated foundations composed of steel pipes that have welded helix-shaped plates configured along their shafts. The piles
- Compact installation equipment.
- Verification of axial capacity using a torque-to-capacity relationship.
There are many layers throughout a construction project, but a solid foundation starts with the investigation, analysis and recommendations provided by the geotechnical engineering team. And having the services of a geotechnical team in-house will benefit a project of any size.
Helical piles offer several advantages over traditional concrete drilled shaft foundations. Read about why helical piles can deliver precisely what you need.
