The culprit was the clay, which expands when it gets wet. “Some areas on the side of the runway swelled more than 12 inches, which is pretty significant heaving,” says Stehmeier. The villain and hero was blue clay, which is common in southwestern Utah, where SGU is located.Īirport Manager Rich Stehmeier notes that the pavement issue first arose several years after SGU opened in January 2011. Ironically, the $26 million project that reconstructed the 9,300-foot runway leveraged the same material that caused the runway to start heaving in the first place. But its routine appearance belies what’s hidden below: a clever feat of engineering and earthwork designed to stop the pavement heaving that doomed the original runway. George Regional Airport (SGU) doesn’t look at all unusual.
