    First Council in Australia to Use a Bituminous Geomembrane (BGM) to Cap a Landfill Site for its Rehabilitation

    Townsville City Council is the first council in Australia to use a bituminous geomembrane to cap a landfill website for its rehabilitation. The $4 million venture is developing the closing cap on the last component of the Hervey Range landfill. The bituminous geomembrane is much less susceptible to leaks and is greater resilient than different products. Council’s Townsville Water and Waste Committee chairperson Councillor Russ Cook stated it had been interesting to see the assignment radically change the site.

    Lake Francis Dam maintenance with GCCM

    The Yuba Water Agency in Yuba County, Calif., was established in 1959 to reduce flood risk and provide a sustainable water supply to the people of the region. Yuba County has historically endured devastating floods, due in part to Gold Rush-era hydraulic mining practices that washed millions of cubic yards of debris into the Yuba River, raising the riverbed and increasing the flood risk.

    GSI to host webinar on lifetime predictions of geosynthetics

    A most frequently asked question regarding all types of geosynthetics is, “How long will they last?” This webinar answers the question for exposed geotextiles and geomembranes assuming that they were properly designed and installed. Furthermore, it compares these new exposed results to earlier lifetime prediction results on covered geomembranes.

    Strain Monitoring Strategy of Deformed Membrane Cover the use of Unmanned Aerial Vehicle‐Assisted 3D Photogrammetry

    Membrane covers are commonly used as floating covers for clean water reservoirs to prevent evaporation and pollution; for landfills to trap hazardous chemicals and unpleasant odour; and for tailing  impoundment  [1–3].  Floating  cover  materials  such  as  high‐density  polyethylene  (HDPE)  geomembranes are very durable, resistant to many different solvents, and have a high strength‐to‐density ratio, and if well‐designed, long service life (in decades) even in harsh environments [2,3]. The Western Treatment Plant (WTP) at Werribee, Victoria, Australia, installed two floating covers to assist with the anaerobic treatment of the raw sewage beneath them, leading to the production of methane‐rich  biogas,  see  Figure  1.

    Uncover the anti-seepage secret of Vulcan Mountain Raytheon Mountain Hospital: "Two Geotextile and One Geomembrane" construction process, find out!

    Although the Vulcan and Raytheon hospitals were built as temporary hospitals to fight the epidemic, they are not “temporary” at all in wastewater treatment: fully enclosed operation, and pumped to the municipal pipe network after the third-level liquid chlorine disinfection; press under the entire base HDPE geomembrane is laid as standard in the landfill, as if wearing "protective clothing", the rainwater is collected and disinfected completely, and no drop of sewage is allowed to enter the ground!

    HDPE Geomembrane composite geotextile

    The composite geomembrane is heated by far-infrared heating on one or both sides of the film, and the geotextile and the geomembrane are pressed together by a guide roll to form a composite geomembrane. With the improvement of the production process, there is also a casting process for composite geomembrane. The form has a geotextile one geomembrane, two geotextiles one geomembrane, two geomembrane one geotextile and the like.

    The difference between needle punched geotextile and meltblown textile

    1. Needle-punched geotextiles, needle-punched geotextiles are divided into continuous filament needle punched geotextile and staple fiber needle-punched geotextiles. 2. Meltblown textile, melt-blown non-woven process uses high-speed hot air to draw a thin stream of polymer melt extruded from the spinneret of the die, thereby forming ultrafine fibers and condensing on the curtain net, Rely on self-adhesion to become a nonwoven.
