American Deep Foundation, Inc. is a deep foundation contractor at 114 Crowatan Rd in Castle Hayne, North Carolina. Its website says it was founded in 1996 and specializes in pile driving, augered piles, micro piles and excavation bracing, with offices in North Carolina and Georgia.
The company works in industrial and nuclear power plants and under strict safety requirements, and says it will review soil and job information to price foundation options. Helical piles appear on the site but the focus is larger driven and drilled piling, so it fits commercial and industrial jobs more than small residential ones.
Service area: the East Coast office covers NC, SC, VA, MD and WV, and the South Central office covers GA, FL, TN, AL, MS, KY and LA. To request a quote, call (866) 951-4339 or the North Carolina office at 910-623-4503. Ask whether helical piles are appropriate for your loads, how capacity is verified and who provides engineering.
