Includes bibliographic references. "In previous studies, spray-in-place rigid urethane foam was identified as having potential, in terms of feasibility of application and relative cost, for use as an impermeable liner in northern tank farms constructed from previous granular materials. However, little was known about the strength, cold-temperature performance and durability of this material. This report summarizes knowledge gathered in a review of pertinent literature and a laboratory assessment of foam samples of several densities and one weathered five-year old sample"--Abstract.
