Francey, William: Analysis of geomembrane welding parameter on long and short-term seam integrity
High density polyethylene (HDPE) geomembrane is the most commonly used material for containment of contaminated fluids, soils, and waste. The geomembrane sheets are bonded together using a hot wedge welder or extrusion gun to melt and fuse overlapping sheets. Installation quality is largely determined by the experience of the welding technician, as there are currently few guidelines on how to adjust welding parameters, especially to suit harsh environmental conditions. Welding speed, temperature, and pressure are welding parameters which are controlled by the technician and need to be correctly balanced to produce an weld which meets field acceptance criteria. However, uncontrollable parameters such as extreme hot or cold ambient temperatures, intense sun exposure, and the presence of moisture can lead to complications during installation. In particular, installation of HDPE geomembrane during extreme cold condition (ambient temperature <-25°C) is known to cause stress cracking along HDPE seams. Laboratory studies are being conducted to examine the effects of the welding parameters have on the various short and long-term properties of a geomembrane. Emphasis will be put on optimizing welding procedures to mitigate stress cracking failures during cold weather installation.
AbdelRazek, Ahmed: Interface transmissivity and hydraulic performance of GCLs in mining and landfill applications
The interface transmissivity between GCL and GMB under various laboratory conditions are being evaluated together with the hydraulic performance of GCL when permeated with solutions representing synthetic mining fluid and MSW leachates. The effect of GMB stiffness and texture, polymer enhancement of bentonite, permeant salt concentration and GCL prehydration conditions are examined for both traditional and multicomponent GCL types. In addition, numerical simulation of leakage in composite liners is also adopted to get a better estimate of leakage rates for various leakage scenarios.
Awad, Ramy: Long-term performance of HDPE and LLDPE geomembranes liners in brine containment and other applications
Accelerated ageing techniques are used to thoroughly investigate the service life stages of HDPE and LLDPE geomembrane liners used in to contain brine solution by monitoring the antioxidants depletion and the induction of mechanical properties degradation ultimately to the geomembrane nominal failure. Different brine solutions are used to monitor their effect on the geomembrane life stages. Another part of the research focuses on a 25-year-old geomembrane used in the containment of PCB contaminated waste. This part will give an insight on geomembranes produced in that period of time, how being in service for that period has affected their performance and how they compare to modern day geomembranes. The effect of initial stress crack resistance on the service life of the geomembrane is also investigated through physical simulation of a landfill liner profile where geomembrane liners are pre-aged to specific stress crack resistance values. A study on double liners is performed through physical simulations which will give insight into the long-term performance of the various components in the composite liner.
Baral, Anil: Performance of highly compacted bentonite and bentonite-sand mixture as sealing material for nuclear waste repositories in a highly saline environment
Bentonite has been considered as a barrier for nuclear waste repositories for a long time. These barriers are constructed between canister and host rock to isolate the nuclear waste material which is placed inside deep repositories several hundred meters below ground level. Therefore, it is very important to understand the behaviour of under hydro-mechanical loading. This research involves laboratory experiments on bentonite and bentonite sand mixture under various test conditions. The Cobourg formation brine model water is consider as a testing fluid to understand how bentonite sealing materials perform when exposed to highly saline groundwater (200-300 g/L). Consideration is being given to compressibility, swelling pressure, water retention behavior, hydraulic conductivity, microstructure observation, sealing of technological voids subjected to pore fluid under different loading conditions.
Di Battista, Vanessa: Performance of Geosynthetic Barriers in Extreme Cold Climates
The performance of geosynthetics is dependent on the installation environment; it is not uncommon for geosynthetics to be used in extreme environments such as the Canadian Arctic or Antarctica. Thus, understanding the impact of external factors, such as freeze-thaw cycles and extreme groundwater fluctuations, on the performance of geosynthetics is necessary to predict their practical viability. Using exhumed samples from Antarctica, various methods, such as x-ray images and permeability tests, are used to qualitative and quantitatively characterize differences in GCLs. Diffusion testing is also being performed on coextruded geomembranes for common groundwater contaminants.
Li, Ti-Kang: Factors affecting GCL hydration and its subsequent performance - especially when damaged
Geosynthetic Clay Liners (GCLs) used as part of composite liner systems typically have a very low hydraulic conductivity when permeated with deionized water or tap water under a certain stress. However, the hydraulic performance of GCL is dependent on the extent to which it is hydrated in hydraulic containment applications. Laboratory experiments are being conducted to investigate the level of moisture uptake by GCL when it is in direct contact with permeant or subgrade. Different types of GCLs either with or without defects are placed in a permeant or on a subgrade to subject them to hydration and the variation of moisture content is being monitored periodically. Hydraulic conductivity tests are performed at the end of test in flexible wall permeameter. Consideration is being given to a range of stresses from low to high and subgrade with different initial moisture contents and grain size distribution are being examined.
Morsy, Mohamed: Performance of HDPE, LLDPE, and BPE Geomembranes in Various Geoenvironmental Applications
Geomembranes (GMBs) are used in various applications including landfills, mining facilities, and potable water reservoirs. In this study, accelerated aging tests will examine: (1) The effect of texturing on antioxidant depletion rate and degradation of physical properties of a high density polyethylene GMB, (2) The effect of morphological changes on the stress crack resistance of a wide range of GMBs, (3) The performance of high density polyethylene (HDPE), linear low density polyethylene (LLDPE), and blended polyolefin (BPE) GMBs in chlorinated water, and (4) The service life of LLDPE and BPE GMBs in heap leach pad applications.
Shoaib, Mohamad: Durability and long-term strength of HDPE geomembrane and its seams in landfill, brine ponds and mining applications

Chou, Alan: Effect of geomembrane defects at Tailings Storage Facilities
Geomembrane have been widely regarded as an effective tool in reducing seepage and hydraulic gradient at Tailings Storage Facilities. However, geomembranes are prone to bear defects (holes) from installation, and their eventual degradation. Through past research, it has been shown that tailings can partially clog up these defects, and limit leakage through the defects. However, this clogging is predicated on several possible conditions: filter compatibility of tailings to the underliner materials, size of defect, and the stress condition. This study explores how sensitive the clogging effect is to the aforementioned conditions through large scale testing via Geosynthetic Liner Longevity Simulators developed at Queen's. The study aims to empirically define performance limits of geomembranes used as barriers in tailings storage applications, in challenging foundation conditions.
Garcia, Jelica: Hydration of GCLs under isothermal and thermal cycling conditions
In landfill composite liner systems, GCLs are initially hydrated by moisture from underlying soil prior to exposure to waste leachate in order to reduce its hydraulic conductivity and improve performance. As a follow-up to Hosney et al’s (2016) research findings on the isothermal hydration of GCLs with powdered bentonite, this study comprises a series of laboratory experiments that monitors the performance of six different types of isothermally hydrated GCLs. The effects of varying subgrade water content, effective stress, bentonite grain size and polyethylene coating on the woven carrier geotextile on the performance of the prehydrated specimens are also investigated. In addition, three GCL types are tested for moisture uptake under thermal cycles and compared to the isothermally hydrated specimens.
