For several years, the U.S. Congress has considered legislation encouraging the use of innovative construction materials. A specific bill termed “Innovative Materials in American Growth and Infrastructure Newly Expanded” or called “IMAGINE,” was first introduced in 2018. It was again introduced in 2021 as a result of the increased infrastructure expenditures anticipated for the Infrastructure Investment and Jobs Act (IIJA), also in 2021. While the bill has not been previously approved and enacted, it was reintroduced in November 2023. As a summary, IMAGINE has these principal goals: 

For the most part, all geomembranes have a similar broad function: A fluid barrier. When comparing, the confusion lies in the fact that they are manufactured by different methods and constructed differently, which result in varying properties to accomplish the broad fluid barrier function. Plus, the definition of “fluid barrier” is subjective depending on a host of site, application, fluid composition and regulatory factors. Key geomembrane properties are required to support the overall function.

As Engineers, we use the term “failure” in a number of ways but know that it implies something did not perform as expected. Was it the fault of the “failed” thing or action, or was it a failure in how it was expected to perform, under those conditions? Regardless, we all know that failure brings negative connotations in many ways, and none are desirable.
