Aggregate Industries U.S., a subsidiary of Holcim Ltd., has acquired Lattimore Materials Corp. (LMC), a ready-mixed concrete producer and aggregate supplier based in McKinney, Texas.

LMC will be a wholly owned subsidiary of Aggregate Industries US Inc. A different subsidiary of Holcim Ltd. has owned a minority interest in LMC since 2007.

"The acquisition of LMC will fit very well into the Aggregate Industries US operation," said Bernard Terver, Holcim Ltd United States Area Manager. "Until now, Aggregate Industries US did not have a presence in Texas. The acquisition of LMC firmly establishes Aggregate Industries US operations in this important area of the United States and allows Aggregate Industries US to fully leverage the very strong positions and reputation of LMC."

Pat Ward, senior vice president, Western Region for Aggregate Industries US, will oversee the organization's operations.

LMC was ranked No. 33 in the 2009 TCP 100; Holcim was No.5.
