Earlier this year, Solmax took on a very hot topic with a free webinar: managing geomembrane wrinkles. This session followed the discussion created by a Geosynthetic Institute webinar in which Dr. Robert Koerner spoke strongly against wrinkles left in or left to develop in a geomembrane installation. Solmax delivered a welcomed talk on the manufacturing approach to the subject. Technical manager D... »

PODCAST: The Push towards Reinvention in Geomembranes

On by Geosynthetica
News and Articles

Many infrastructure applications rely upon geosynthetic barriers. Over time, we’ve seen the specification of 40 or 60-mil black high-density polyethylene geomembranes become so common that black HDPE can feel almost like a commodity product. In part, this seems at odds with the critical containment these geomembranes provide. But, it is also in part a testimony to how the geosynthetics manufacturi... »

EVOH Layers and Better Gas Barrier Performance for Geomembranes

On by Geosynthetica
News and Articles

Geosynthetic barriers perform exceptionally well in liquid containment applications, but gas barrier performance can still be improved. Volatile organic compounds, for example, can diffuse through barrier systems. The rate is low, but the incorporation of an EVOH layer in a geomembrane has shown that the diffusion rate of VOCs can actually be much lower. Applications that utilize geosynthetics and... »

Geosynthetics are playing an enormous role in updating how coal combustion residuals (CCRs) are managed and stored, both in the near term and for long-term environmental security. INOVA Geosynthetics is now bringing together the engineering insight of three major North American geosynthetics companies to promote CCR capping systems. The Coal Ash Performance Products (CAPP) approach from Pennsylvan... »

The Lighter Side of Geomembranes

News and Articles

Geomembrane installations often cover substantial areas. Landfill cells pose enormous footprints. Oil and gas pits, industrial processing ponds, and wastewater containment ponds are large installations too, and each year they tend to be built a little larger. The scaling up of these facilities is not just a matter of achieving better operational economics for the facility owner; it’s also because ... »
