Western Specialty Contractors Restores and Waterproofs Nile Kinnick Stadium at University of Iowa

Western Specialty Contractors – Des Moines, IA Branch used its concrete/masonry restoration and waterproofing expertise to repair and protect portions of historic Nile Kinnick Stadium – home to the University of Iowa Hawkeyes football team.

Located in Iowa City, IA, Nile Kinnick Stadium was named after University of Iowa football star Nile Kinnick who won the Heisman Trophy in 1939 and died in 1943 while serving in World War II. Originally named Iowa
Stadium, the facility was constructed in only seven months between 1928 and 1929 using horses and mules as the primary heavy-equipment movers. The stadium underwent major renovations in 1956, 1983, 1990, 2004 and 2016. Its current capacity is 69,250, making it one of the 20 largest university-owned stadiums in the country.

Most sports stadiums and arenas in the United States are made of reinforced and precast concrete with steel seating supports and railings. Unfortunately, an even more universal characteristic is their openness and vulnerability to the elements — in addition to the wear and tear they receive from fans. All of these forces combine to take a toll on their structural integrity.

Without routine maintenance and protection, these concrete structures are subject to cracking, spalling and
structural damage from movement and reoccurring freeze and thaw cycles.

Engineering firm Shive-Hattery Architecture + Engineering worked with university officials to determine the scope of work required by Western to restore and protect Kinnick Stadium, which included:

Waterproofing Membrane –
Grandstands (115,000 sq. ft.)

  • Joint sealant replacement
  • Vertical spall repairs
  • Concrete crack repairs
  • Concrete step replacement
    Concourse Soffit and Suspension
    System Repair/Replacement
  • East Concourse repair plaster and
  • West Concourse replacement of the
    entire suspension system and plaster

Masonry Repairs – Southwest Corner
of Stadium

  • New through-wall flashing
  • 100% tuckpointing
  • Parapet rebuild
  • Multi-wythe brick replacement

Challenges on the project resolved by Western included scheduling and mobilizing work around unanticipated stadium events and building custom aluminum soffits that required multiple shop drawing revisions to ensure a proper fit.

Western’s craftsmen started the $1.2 million restoration project in May 2022 and completed the work on schedule in August 2022 and within budget.
