Specialty Industrial Construction Services

Advanced construction capabilities built on decades of hands-on expertise — from continuous slipform concrete construction for grain bins and silos, to precision industrial millwright and equipment installation services.

Specialty Skills That Few Contractors Can Match

Not every industrial construction contractor can slipform a 36-foot-diameter concrete grain bin to within a millimeter of vertical, or precision-align a high-speed pellet mill drive system to manufacturer tolerance. Todd & Sargent has been doing both for generations. These specialty capabilities are a core reason why agri-industrial owners trust us with their most complex projects.

Slipform Concrete Construction

Continuous poured concrete construction for grain storage bins, silos, elevator legs, and industrial storage structures. Todd & Sargent has over 90 years of slipform experience — having constructed hundreds of concrete storage structures across the US and Canada.
