Geofoam is used to create the formwork required to shape the bridge’s three concrete piers. “We had never used foam as concrete forms before, but this project really opened our eyes to the possibilities of this product and its ability to help us solve construction challenges in the future,” added Clyde.

Sinkholes. Massive discharges of untreated wastewater. The consequences of pipeline ruptures and breaks can be disastrous.
Sewer and water pipelines are vulnerable to faulting, seismic activity and other ground movements, but ongoing research is showing EPS geofoam to be a material with great potential for protecting them.
Steven Bartlett, associate professor of civil engineering at the University of Utah, and his team have been examining geofoam’s mitigating effects on pipeline damage.
In December 2013, Bartlett’s research on EPS geofoam was put to use in the repair of a severed sewer pipe in Brian Head, Utah. This was the second time the sewer line had been severed due to the dewatering of a deep sandy layer beneath the pipe, which resulted in significant consolidation, settlement, deep cracks and fissures.
During the first repair, 10 inches of settlement and 6 inches of lateral movement were noted. Tom Stratton, Brian Head Public Works director, and his crew devised a plan to repair the damaged pipeline. After consulting with Bartlett and engineers Chet Hovey, P.E., of Advance Environmental Engineering, and Joel Myers, P.E., of Gem Engineering, the team concurred that geofoam should be incorporated into the repair in order to reduce settlement issues and protect the pipeline from future damage by allowing it to be adjusted vertically from the surface.

Dr. Steven Bartlett had a busy summer traveling to China and Turkey to present various topics regarding the use of EPS geofoam for Civil Engineering applications. Topics included the protection of pipelines from earthquakes using EPS geofoam, which was presented at GeoShanghai 2014 (Protecting Pipelines).
In Turkey, Dr. Bartlett also presented to several conferences and seminars regarding EPS geofoam application (Geofoam Applications). For his efforts, the Expanded Polystyrene (EPS) Board of Directors of Turkey (EPSDER) presented him a recognition award. The award states:
“In great appreciation and consideration of your time, effort and support in the development of geofoam applications in Turkey.”
