Navigating unexpected contaminants with your geomembrane system

March 5th, 2024

By Felon Wilson Geomembranes are long-term containment barriers. As such, it is not uncommon for them to be called upon to contain liquids not originally planned. That is particularly true in applications which are more likely to produce changing or varying liquid containment requirements. This blog series will dig into how unexpected contaminants can be […]

The rise of BGMs: A decade of transformation in the geomembrane industry

November 13th, 2023

A decade ago, bituminous geomembranes (BGMs) were a relatively unknown player in the landfill and mining industries. Fast forward to the present day, and BGMs have emerged as a significant disruptor, posing a formidable challenge to traditional high-density polyethylene (HDPE) geomembrane manufacturers. The industry landscape has shifted dramatically, with BGMs steadily gaining market share and […]

How geomembranes help to improve water quality, lower costs and increase efficiencies in wastewater treatment

November 8th, 2023

By Felon Wilson Part 1: Wastewater Industry in North America “We still think of air as free. But clean air is not free, and neither is clean water. The price tag on pollution control is high. Through our years of past carelessness, we incurred a debt to nature, and now that debt is being called.”– […]

New developments in geomembranes for pit heat storage

October 9th, 2023

Large solar thermal systems need large heat storage capabilities. Especially if the solar heat is to contribute significantly more than 25 % to a district heating network. Pit thermal energy storage (PTES) is a cost-effective way to build large heat storage facilities with 100,000 m3 and more. A key component of these storage pits is the […]

Five major considerations when designing geomembrane mechanical attachments

September 18th, 2023

By Felon Wilson The terms attachments, penetrations and terminations are often considered synonymous, or at least in the same family, when used in the context of geomembranes. This post will focus on attachments and specifically a review of ASTM D6497, one of the main guides for geomembrane mechanical attachments. ASTM D6497 (General Practices for Geomembrane […]
