Seaman Corp. launches XR-FR, a fire-retardant flexible geomembrane

December 20th, 2021

A reinforced flexible geomembrane for secondary containment of spills is a good choice because they don’t leak, are less expensive and don’t require costly subgrade consideration and amendment. Widely used for oily wastewater and fuel containment, the XR-FR Fire Retardant Flexible Geomembrane is suitable for use with flammable liquids. Photograph courtesy of Seaman Corp. Seaman […]

Geosynthetic solutions to improve safety in mining applications

October 6th, 2021

Photograph courtesy of AGRU America What do Tesla, Apple and Ford have in common? They all rely on mines that produce metals like lithium, which drives our technology-hungry world. Now, more than ever, mining operations must run efficiently to meet increasing demand. Equally as important is supporting positive public beliefs on mining. Mining operators must incorporate […]

Geosynthetics for CCR, PFAS and energy applications

October 1st, 2021

This issue of Geosynthetics magazine delves deep into two innovative uses of geosynthetic clay liners (GCLs) in very different applications: coal combustion residual (CCR) leachates and per- and polyfluoroalkyl substances (PFAS) mitigation in landfills. We also examine three case studies of energy companies using high-density polyethylene (HDPE) geomembranes for flowback water in water evaporation/recycling ponds. […]

Heat resistance of geomembranes

October 1st, 2021

Q: We have a question in regard to the heat resistance of geomembranes. We are interested in paving a road over a geomembrane with hot mix asphalt and want to know if the geomembrane will continue to function as a moisture barrier? A: The answer to this depends very much on the formulation from which […]

Measuring strain in geosynthetics

October 1st, 2021

Q: Currently, what is the best-known method to measure strains in geosynthetics? We are having arguments between results generated from crosshead movement and extensometers. A: This question arises often when comparing ISO 527/ASTM D638 and ASTM D6693 results. The former requires an extensometer, where the latter utilizes crosshead deflection and assumes gauge lengths. This discussion […]

Energy industries use HDPE liners for flowback water evaporation/recycling ponds

October 1st, 2021

FIGURE 1 To increase evaporation with low costs in mind, a “weep” system was added at Danish Flats to allow water to flow and fan out over the surface of the HDPE liner that is above the waterline. The problem to be solved is the disposal and recycling of millions of gallons of production water […]
