The new sod is a combination of natural Kentucky bluegrasses reinforced with polypropylene fibers that are sewn into the sod every three-fourths of an inch to make the surface more durable.
Since Heinz Field opened in August 2001, the all-grass playing surface had taken a pounding with games played by the Steelers, University of Pittsburgh Panthers and local high schools. The Steelers were forced to replace the chewed-up Heinz Field grass three times last year.
