DOWNLOAD NOW! Geofoam Applications for Transportation Infrastructure
Presented by Steven F. Bartlett, Ph.D., P.E. (Univ. of Utah)
Webinar recorded May 21, 2019.

Dedicated to advancing the use of fabricated geomembranes through education, research, and technology transfer.

WHY?
Factory fabrication reduces field welding, reduces installation time and costs, allows modular construction and provides consistent seam and liner quality.
