  • 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 ...

  • Build your pond to last with a liquid liner

    Build a pond without providing proper sealing and you'll probably be watching your money getting washed down the drain. Pond cracks, pond holes and pond leaks can be a persistent and costly problem so heading them off before they start in the construction process is a very good idea. That means paying particular attention to lining your ...

  • The Basics of Slope Stability Analysis for Geosynthetics

    Slope stability analysis is vital to preventing slope failures in a variety of engineering applications including landfill design, roads, dams and embankments, to name a few. Proper analysis anticipates both natural and manmade slopes and failure of foundations and retaining walls. This blog covers the necessity of slope stability analysis, how to conduct the analysis and the role of ...

  • 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.” ...

  • Case study - Algae control in raw water reservoir Ecuador

    Before the installation of the LG Sonic e-line equipment algae grew on the surface and settle down on the liner before entering the drinking water treatment plant. To cover the 24.000 m2 of water surface, it was decided to install 3 devices.   The Challenge: Green Algae Covering the Sides of the Lagoon Located in Santa Elena’s peninsula, the 42.000 m3 raw water ...

  • REDmeters - Blue Paper

    REDmeters: Abstract The process of controlling and the cost of monitoring slurries in many industries are normally accomplished using various continuous mass flow systems. These types of systems usually contain a magnetic flow meter and a line density meter. There is inherent cost associated to these systems due to the inaccurate nature of these meters. Some meters on the market boast up to ...

  • Bozeman wastewater treatment plant, Crisafulli FLUMP with pond liner protection system-case study

    Paul Layton, Assistant Superintendent, City of Bozeman, MT Public Works Dept. Commenting on the Crisafulli FLUMP with Crisafulli’s Pond Liner Protection System Purchased in 2003 for Bozeman’s Wastewater Treatment Plant "I really like the remote-control aspect of the unit. We can just have an operator sitting up here on the shore, out of the sludge, operating in a very clean ...

  • 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 ...

  • Analysis of acid transport through multi-phase epoxy mortars for wastewater structures

    The characteristics of acid migration through epoxy mortars were examined. Diffusion coefficients of typical sewer bio-metabolised acids: sulphuric, nitric, citric and oxalic acids were determined by gravimetric sorption method and fitted to the multi-phase Jacob–Jones model. Acid permeation was characterised by hindered pore diffusion with the extent being determined by the polarity of ...

  • Interest Growing in Mining Applications for Geosynthetics

    Some 40 percent of the geosynthetics manufactured today are used by the mining industry, according to one estimate, and there are predictions that figure will increase as the industry continues to adopt mining technologies that help improve efficiency and protect the environment. Jack Caldwell, an engineer at Robertson GeoConsultants, has gone as far as to say, “We believe that ...

  • Using Geosynthetics in Slope Stability

    The majority of slope failures within the geosynthetics industry can often be avoided with proper engineering and material selection. However, the factors that affect slope stability can be difficult to discern and measure. Soil thickness, seepage forces, seismic forces, gas uplift, geomembrane texturing, engineering and provision of reinforcing elements are only a few of the factors affecting ...
