Dallas Cowboys Stadium
EPOGROUT 758™, part of the LATICRETE® L&M® product line supports Huge Arches in New Dallas Cowboys Stadium
They say that the biggest things always come from Texas! It may be true with the new Dallas Cowboys stadium (the largest stadium in the NFL).
Things have never looked more exciting for the local citizens, fans, and building industry in the Dallas metroplex. This stadium is the nucleus of a 135-acre mega complex that, along with the new stadium, includes a mix of 900,000 sq. ft. of retail, 150,000 sq. ft. of office space, as well as residential, hotel and entertainment venues.
LATICRETE L&M Construction Chemicals played an important role in the building of this magnificent stadium through the selection of its high performance, epoxy-based grout, EPOGROUT 758™, to support the super-sized twin arches of the stadium.
To support the immense weight of the roof, four enormous spread footer pads were poured with about 60-70 feet below grade and approximately 40 feet showing above. These concrete support elements were formed with a 72o angled top surface which provides a firm foundation for the steel beams. Between this 40- foot high concrete footer and the steel from the main span arches, the high strength properties of EPOGROUT 758™ came into play by supporting the load of the arched roof supports.
The main roof span arches are the “keystone” architectural signature of the stadium's master designer, HKS of Dallas. Engineering spec's called for an epoxy-based grout formulated to meet the demanding project requirements which included precision-grade, flowable placement properties and 7-day cure compressive strength properties of up to 14,000 psi or greater. EPOGROUT 758™ satisfied the demands of the project.
