Subsurface Construction Corporation

Subsurface Construction Corporation refers to two distinct entities. The US-based company operates as a design-build geotechnical specialty contractor, primarily serving the Southeast US. With over 20 years of experience, it focuses on excavation support, earth retention, deep foundations, and ground improvement. The company is headquartered in Smithfield, NC, with an additional office in Greenville, SC, and serves areas including North Carolina, South Carolina, Virginia, Tennessee, and Georgia.

The Canadian entity specializes in deep foundations, driven piling, and helical/screw piling, operating mainly in Alberta. Based in Calgary, it has additional sites in Grande Prairie, Okotoks, and Fort McMurray. Both companies emphasize reliable service and collaboration with civil and geotechnical engineers, general contractors, and project owners.
