Alternative stress cracking surfactants identified for HDPE geomembrane testing
February 9th, 2022
The Australian geosynthetics testing company ExcelPlas discusses the search for alternative stress cracking surfactants to the pollutant Igepal CO-630. Photograph courtesy Solmax Geosynthetics testing company ExcelPlas in Highett, Victoria, Australia, has identified two alternative stress cracking surfactants for high-density polyethylene (HDPE) geomembranes. Igepal™ CO-630, the non-ionic surfactant used in high-density polyethylene (HDPE) stress cracking bath, […]
Fusion-welded HDPE geomembrane patch
February 1st, 2022
Q: I need to make sure of what the minimum area is for a fusion-welded HDPE geomembrane patch with a 60-mil (1.5-mm) thickness that should be fusion welded instead of extrusion welded. Also, when does one need to replace a panel that is damaged (i.e., the percent of damage allowed to be repaired)? Thank you […]
EPDM geomembrane for a water application
February 1st, 2022
Q: We are looking at a life-cycle study for the usefulness of an ethylene propylene diene monomer (EPDM) geomembrane for a water conservation application. Request to kindly share the information for our study. Regards. A: An EPDM geomembrane is going to lie flat on the subgrade soil without wrinkles (no field-induced stress). Therefore, it will […]

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 […]

Although preshaped rigid liners exist, they are not normally what you would choose for your fish-stocking pond. No matter how small or large the pond you have in mind, your best option today is flexible […]
Geomembrane freshwater bladders for eco-friendly beach resort
August 31st, 2021
