We crush it and put it right into our cement process.” Noting that his team is “fortunate” to benefit from the skills of Hunter Stone’s people, Cement and Southwest Ready Mix Division President Karl Watson is quick to second McCormick’s enthusiasm. “The depth of the aggregates focus and the expertise they bring to this part of the cement-making process is something most cement plants do not get to experience,” he says. With much of the figurative heavy lifting behind them, folks at Hunter appear ready for a bright future, says Allen, casually adding that even the quality of rock at the new operation exceeds what was produced at New Braunfels Quarry. Roberts sums it up nicely. “Hunter Stone enhances our position along the important I-35 corridor between San Antonio and Austin,” he says. “It is a generational position that provides significant opportunities for growth in an important market.” ▼ www.martinmarietta.com | September/October 2017 The Conveyor 21 HUNTER STONE The Raw Story ■ 45 days The length of time between when the first bit of rock went through Hunter’s primary plant on Feb. 15, 2017, to when the site was fully operational on March 31. ■ 25 percent The increase in plant production capacity at Hunter Stone over New Braunfels Quarry.
