Technical Foundations

Technical Foundations, Incorporated is a specialty deep foundation contractor at 100 Drybridge Ct in Sandston, Virginia. Its website says it has about 30 years of operation and is SWaM certified, with membership in DFI, ASCE and ISN.

The company lists auger cast piles, micropiles, helical piles, soil nails, shoring systems, grouting services, rigid inclusions, load testing, value engineering and design-build solutions. That puts it on the commercial and engineered side of the market, where helical piles are one tool among several deep foundation options chosen to suit soil and load.

Its stated service area covers Virginia, Maryland, South Carolina and North Carolina. Contractors, developers and engineers can call (804) 328-4500. Ask when helical piles are preferred over micropiles or auger cast piles for the project, whether design and load testing are included, what installation torque targets will be used, and whether the firm will work on smaller residential jobs.
