Oremus Material supplied 12,632 cubic yards of concrete for this prestigious project, which broke ground in May 2012 and opened before the start of the 2013-14 school year. The job required us to deliver 11,000-PSI concrete in the heat of summer, when temperatures typically reach 100 degrees or more, all while keeping mix temperatures within specifications. Problem solved: just add ice (and lots of it!) while using chilled water on the spray bars.
