Harbison Walker Refractories

Established in 1865 under a different name, Harbison-Walker Refractories once used asbestos as a mainstay of its products, which included fireproof brick and refractory cement. By the 1990s the company faced more than 200,000 asbestos-disease claims.

Harbison-Walker Refractories started under the name Star Fire Brick Company with its primary products including fireproofing cements and bricks made so they withstand high temperatures. By 1967, Harbison-Walker merged with Dresser Industries, a subsidiary of Halliburton, a company made famous under the leadership of former Vice President Dick Cheney.

Quickly, Halliburton learned it would be flooded with asbestos claims from Harbison-Walker Refractories. As a result of the Harbison-Walker’s bankruptcy proceedings in 2002, the DII Industries, LLC Asbestos PI Trust was established and funded with more than $4 billion. Today, Harbison-Walker Refractories is known as HarbisonWalker International. The company serves industries that include cement and lime, energy, chemical and hydrocarbon and mineral processing.
