Accurate Defaults Detection and Location of Buried Geomembranes: A Novel Radiofrequency Approach

点击翻译按钮获取中文摘要

Geomembranes have made a major contribution in industrial and environmental containment applications.**They are essentially impermeable polymeric lining materials used as fluid barriers in geotechnical engineering**applications.**To face their integrity by soil-geosynthetic interface strength or during and after the installation, a detection**and location of defaults is a crucial factor in their overall usefulness.**This proposal addresses a subject of current interest for Solmax International Inc, a Canadian-based company**and an industry leader in the production of high-quality polyethylene geomembranes for industrial and**environmental containment applications. The products are used by the biggest names in the mining, energy,**waste management, water, and civil engineering sectors.**Through the ENGAGE program, a research team from the INRS-EMT EMT in collaboration with the R&D**department of the industrial partner SOLMAX. Inc will design and develop a non destructive test setup to**improve defaults and cracks detection and location in buried geomembranes.**Important issues related to géomembrane reflective layer performance, frequency operation and default size**detection must be achieved.**The proposed project will be highly cost effective because of the available facilities at INRS-EMT RF**laboratory, where a critical mass of infrastructure and resources than can be exploited for its success. The**objectives of the proposed research are (i) to design a reflective layer to exploit the geomembrane as**radiofrequency barrier (reference) (ii) to develop and build a portable measurement setup adapted to the**specific needs of the industrial partner, and (iii) training of highly qualified personnel to respond to scientific**and technological challenges of our society.
