Tindall Corporation

Tindall Corporation is a precast concrete manufacturer headquartered in Spartanburg, South Carolina, founded in 1963 and employee-owned, with plants serving the Southeast, Mid-Atlantic, Texas and the Midwest. The firm produces structural and architectural precast, total precast building systems, parking structures, prison and detention systems, utility and infrastructure products, and wind and energy components. Tindall is a partner on Oak Ridge National Laboratory’s DOE-funded project developing limestone, activated clay and calcium sulfate blends that use mechanochemical clay activation to cut portland cement content, one of four cement and concrete awards in DOE’s $117 million September 2026 industrial package. That partner role matters because low-clinker mixes have to survive contact with a real precast production schedule, not just a lab.

The business started in 1932 as a small concrete manufacturer working out of a shed in Spartanburg. That shed is still standing on the Spartanburg site. When the Lowndes family bought the company in 1963, it had six employees and made concrete utility pipe.

Current figures from the company: more than 1,500 employees nationwide, over 10,000 completed projects, more than 100 graduate engineers and over 39 professional engineers. Six precast manufacturing facilities operate across South Carolina, Virginia, Georgia, Mississippi and Texas, five of them PCI-certified, and divisions are organised by state territory plus Infrastructure, Headquarters and Atlanta Structural Concrete.

T-SLAB is the product worth understanding. The name stands for Tindall Superior Lightweight All-Purpose Beam, and it is a fully precast floor system in which roughly half the slab volume is lightweight concrete. That mix lets spans run up to 75 percent longer and widths reach twelve feet. Because the pieces are cast in a plant, MEP runs, floor heating, bathroom drains, integral balconies and block-outs can be embedded during production rather than chased or cored later. The practical schedule effect is a reduction in crane lifts of 50 to 67 percent depending on bay layout, which on a multi-storey residential or dormitory job is where the time actually goes.

T-SLAB projects include the Whitis Residence Hall at the University of Texas, Upper Quad North Residence Hall at Virginia Tech, dormitories at Western Carolina University, the Bakery Loft Apartments in Richmond, The Icon Apartments, the Star EV office building, and a weight room addition at Travelers Rest High School.

The Building Systems division targets commercial, corrections, data centers, institutional, manufacturing, mixed-use, parking and warehouse work. Infrastructure is organised around heavy civil, petrochemical, power and energy, and utility products.

Founder William Lowndes III wrote the company’s purpose on a pocket-sized card, which is where the Engineered to Serve motto still in use came from. He served as a Zone Director on the PCI board and as a director of the Spartanburg Chamber of Commerce, and received South Carolina’s Order of the Palmetto.
