A rich St. Louis heritage

The company’s founding organizations, Smith & Brennan Pile Company and Wabash Drilling, both played major roles in the development and progress of the St. Louis area. Smith & Brennan Pile Company was founded in 1907 by a building commissioner of St. Louis and quickly became a leader in the manufacture and driving of precast concrete piling.

Wabash Drilling Company was founded in 1896 and incorporated as Wabash Drilling Company in 1915. In 1960, Wabash Drilling merged with Smith & Brennan Pile Company. Together, they placed foundations under most of the major buildings and plants in the St. Louis metropolitan region. These two companies became known as Subsurface Constructors in the early 1980s.
