Geomembranes can fail for a variety of reasons. A failure in a geomembrane can result in serious damage to the surrounding environment and ecosystem. In order to help keep your geomembrane performing at its best. Here are three common geomembrane failure mechanisms to keep in mind.
Ethylene interpolymer alloy (EIA) has demonstrated superior chlorine resistance and has gained widespread acceptance in the geomembrane market as a result. So what exactly are EIA Geomembranes and the properties that afford them superior chlorine resistance?
The three largest Naval Fuel Depots in the world rely on a flexible geomembrane for secondary oil containment for fuel storage. Secondary containment is provided both under the floors of the tanks and lining the fuel spill containment berms.
Geomembrane liners are often used in impoundments to prevent the migration of wastes out of the impoundment to the adjacent subsurface soil, groundwater, or surface water. Impoundment liners are used significantly in the energy industry to contain fresh water and wastewater, drilling waste, evaporation pits, and coal ash. Geomembrane liners used in these types of applications are made from a wide range of polymeric materials and different types of constructions.
How do you choose the right one for your exact application? In order to prevent contamination of the surrounding environment, careful consideration must be given to determine the best high-performance geomembrane liner that meets the precise requirements of the impoundment.
Reinforced geomembranes can be specified in a variety of scenarios, from floating covers to secondary containment liners. Highlighted below are three of the most common reinforced geomembrane applications.
There are many uses of geomembrane liners. They can be used for floating baffles, secondary containment, wastewater impoundments, and more. It’s easy to bypass the important items and make blunders when selecting and specifying a geomembrane. Below are the five biggest mistakes in the selection process and how to avoid them:
When designing a pond or lagoon, preventing leaks is a major concern. However, determining the best geomembrane liner for your project can be an extremely daunting task. You have to decide between reinforced and unreinforced geomembranes, which material and thickness is best, and between a myriad of other physical properties that could play a part in the success of your project. As a result, people oftentimes choose a natural clay liner because it is the less complicated choice.
Dr. Robert Koerner, professor emeritus of civil engineering at Drexel University, is a highly respected professional in both the geosynthetic and engineering communities. In his webinar, “Wave (or Wrinkle),” Koerner covers unreinforced geomembranes, such as HDPE, and how geomembrane waves or wrinkles can be somewhat prevented and/or fixed. Here is an overview of the webinar:
