  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • How to fit a box-welded pond liner for a perfect water feature

    Box-welded pond liners are also commonly referred to as tailored-to-fit, bespoke, made-to-measure or tailor-made pond liners. All terms are recognised by professional landscapers and by pond liner manufacturers. Suited to formal pond designs, a box-welded pond liner provides the best fit with no unsightly seams or folds. A ...

  • 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 ...

  • Road Over Sensitive Groundwater Areas - Case Study

    When constructing or extending new roads, the responsible designers and contractors are increasingly faced with the task of preventing soil contamination. Therefore, measures for the protection of the groundwater are necessary in more and more cases. The corresponding requirements and specifications for such measurements are regulated in the "guide-line for constructional measurements of roads in ...

  • Canal sealing with Bentofix case study

    After the first pilot project installation of a geosynthetic clay liner (GCL) in a 1 km long section of the Havel-Oder-Waterway in 1997/98, approved by the local German Water and Ship Authority a second project followed shortly after. In a 500 m long section of the Dortmund-Ems-Canal a newly developed innovative GCL was installed under water. The installed GCL was Bentofix BZ 13-B, a ...

  • 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 ...

  • Bali’s first modern landfill design case study

    Bangli Regional Landfill in Indonesia’s Bali province is located about 60km outside of Denpasar, the provincial capital and home to more than 500,000 residents. The region hosts Ngurah Rai International Airport—the main entry point into Bali—and numerous tourist destinations along Bali’s popular white sands beaches. When the Indonesian central government approved ...

  • Bentofix® sealing at Toulouse-Blagnac Airport case study

    One of the largest infrastructure projects in Europe in recent years has been in Toulouse-Blagnac in France on the premises of the airport and the Airbus factory where in future the new Airbus A 380 is to be built. During the course of this construction project not only hangers where the wide-bodied aircraft is to be assembled were built but the whole infrastructure was aligned to ...

  • Locating Leaks in Geomembrane Liners of Landfills Covered With a Protective Soil

    ABSTRACT The electrical leak location method was used to locate leaks in the geomembrane liners of single-lined and double-lined landfills covered with a protective soil cover. The landfills ranged in size from 0.40 hectare (one-acre) to 3.2 hectares (eight-acre). Water in the leak detection system under the primary liner indicated the primary liners were leaking. The principal of ...

  • The Advantages of a Box Welded Pond Liner

    There’s no time like the New Year for good intentions – and one which will pay dividends for many years to come is to create a garden pond. One of the first choices you’ll have to make is the type of liner to use. The material itself is a no-brainer – always use a synthetic rubber liner rather than polythene; synthetic rubbers are much tougher and longer lasting than the ...

  • Robot procedure: Long-term experience with the KATE procedure

    For some time the topic of the useful life for repair procedures has been a matter of controversial discussion. In the process, giving across-the-board indications of useful life for "repair procedures" has increasingly come to be seen as indefensible. Even when, in addition, a separate approach for different groups of repair procedures - "robot procedures" for example - is suggested, this kind ...

  • Measuring a giant one step at a time

    Once construction is complete in 2013, the Columbus Upground Reservoir (CUGR) will be the largest continuously-lined lagoon on the planet, nearly twice as large as the lagoon currently holding that title. The sheer enormity of the project has been compounded with difficulties from the beginning of construction to make it one of the most challenging geomembrane-lined structures ever built. ...
