  • PVC Geomembrane Liner for Waste Containment in Wuhan - Case Study

    PVC geomembrane liner is a kind of impermeable liner, which is widely used in the modern municipal solid waste containment system. PVC is an abbreviation for Poly Vinyl Chloride. They are installed in the side and bottom liners to inhibit flow of leachates and thus prevent the contamination of groundwater. Manufactured by the calendaring or extrusion process, BPM PVC geomembrane has high puncture ...

  • Playing with blocks...in the road

    Anyone old enough to remember when “Styrofoam” was considered detrimental to the environment (it can last for decades in a landfill) will appreciate the latest usage of this same technology in rebuilding our infrastructure. Many of us fondly remember the fun we had playing with building blocks as a child, e.g. Lego’s®.  In today’s construction world, EPS Geofoam ...

  • EPT New Report Solves Geomembrane Acronym Puzzle

    Elvaloy®, patented by DuPont in 1973 has been used as a geomembrane plasticizer for decades. It was developed to provide a solid plasticizer or polymer to replace liquid plasticizers that would make PVC flexible without concerns of plasticizer migration. That much is clear. But what is very blurry is the usage of many of the acronyms and names used in connection with this product. There is ...

  • Why the Berry Amendment is -Berry Good - for America

    In 1939, the United States Military had slightly less than 335,000 service men and women in our Armed Forces.   Shortly after the December 7, 1941 attack on Pearl Harbor, this number would change rapidly.  In preparation for war, President Roosevelt stated to the country shortly afterwards, that in order to achieve victory, “Powerful enemies must be out-fought and ...

  • PVC Geomembranes - Good, Better, Best

    Are different grades of PVC Geomembranes available or are they all the same? There has been a common misperception in our industry that all polyvinyl chloride (PVC) membranes are the same. The fact is that this is far from the truth and as we explain in this blog there are several different grades, and each has its own specific properties with respect to geomembrane applications. Without ...

  • Measuring Geomembrane Tensile Strength – 1” or Dumbbell?

    Abstract: Specifying a tensile strength or % elongation for any given application is necessary to avoid any possible failure in the geomembrane.  There are many factors to consider including: testing equipment, thickness, load cell, type of grips, and sample geometry.  Although ASTM D7176 currently requires a 1” tensile strip, they will be considering a dumbbell-shaped sample as ...

  • Designing With Geosynthetic Clay Liners

    In construction, preventing the penetration of liquids and gases is essential to maintaining the integrity of a structure. Often, containment is just as important, especially when dealing with chemical contaminants or other waste. When looking to stop the spread of contaminated liquids and gases, there are few tools as effective as geosynthetic clay liners (GCL). Read on to learn how to design ...

  • Examining the benefits of HDPE geomembrane

    Comparing various geomembranes for your next geosynthetic application? Don’t overlook high-density polyethylene (HDPE) geomembrane. HDPE has been in use for decades and during that time a number of studies have been conducted to test its longevity and ability to meet environmental sustainability project requirements. Here, we explore some of those studies to examine the benefits of HDPE ...

  • Comparing nonreinforced and internally reinforced GCL

    Water is one of the most destructive forces on the planet, eroding everything from continents to human-made wonders. Water is also a vector by which contaminants spread from landfills and other waste reservoirs. Therefore, creating effective water seals has been a top concern in construction. For many years, factory-fabricated clay products have been the barrier of choice against water and other ...

  • Improving Life-Cycle Performance with Pavement Interlayers

    In an environment of limited and decreasing budgets in the private and public sectors, it is increasingly important that investments made in pavement infrastructure are maximized to their fullest potential. Pavement interlayers, also known as geosynthetics, can be integrated into asphalt mix overlay applications to limit the intrusion of water and reduce the reflective cracking, thereby promoting ...

  • What the Build America Bureau Means for Geosynthetics

    The Geosynthetic Materials Association anticipates higher demand for geosynthetics on the heels of the Fixing America’s Surface Transportation Act, or FAST act, and the recent addition of the Build America Bureau. The new group was created to support the $305 billion FAST Act, which provides long-term funding for U.S. infrastructure planning and ...

  • Watch your Language! Geosynthetics vs Traditional Materials

    During GeoAmericas 2016, Dr. Neil Dixon’s sustainability keynote touched upon many topics for the future of geosynthetics. While sustainability drove most of the lecture, a few of his ideas simply approached how the field positioned itself in the marketplace. He suggested, for example, moving the field away from isolating language like “versus traditional materials.” ...

  • The Lighter Side of Geomembranes

    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 ...

  • Landfill Liners Vary by Application

    It was in 1991 that the Environmental Protection Agency promulgated its Criteria for Municipal Waste Landfills that set location restrictions, design and operating standards, groundwater monitoring requirements, corrective actions, closure requirements, and more for landfills. It was these rules that mandated that landfills be lined on the sides and bottom before waste is deposited and capped on ...

  • Capping of black devon landfill, Alloa, Scotland case study

    The area of contention was Black Devon, a pre legislative landfill of the old „dig and dump“ variety on the banks of the river Forth, outside of Alloa, Scotland. Alloa is situated at the foot of the stunning Ochill Hills in the county of Clackmannanshire and is close to the port of Grangemouth. The landfill had been accepting wastes over many years from neighbouring industries ...
