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.

土工膜在工业和环境控制应用方面做出了重大贡献。**它们本质上是不渗透的聚合物衬里材料，在岩土工程应用中用作流体屏障。**要通过土-土工合成材料界面强度或安装期间和之后来面对其完整性，检测**和定位默认值是其整体实用性的关键因素。**本提案涉及加拿大公司**和生产用于工业和**环境密封应用的高质量聚乙烯土工膜的行业领导者Solmax International Inc .当前感兴趣的主题。这些产品被采矿、能源、废物管理、水和土木工程领域的知名企业所使用。**通过ENGAGE项目，来自INRS-EMT EMT的研究团队与工业合作伙伴SOLMAX的研发部门合作。公司将设计和开发一种非破坏性测试装置，以改进土工膜的缺陷和裂缝检测和定位。**必须实现与g郁闷膜反射层性能、频率操作和默认尺寸**检测相关的重要问题。**拟议的项目将具有很高的成本效益，因为INRS-EMT RF**实验室有可用的设施，那里有大量的基础设施和资源，可以为其成功利用。拟议研究的目标是(i)设计一个反射层，利用土工膜作为射频屏障（参考）；（ii）开发和建立一个便携式测量装置，以适应工业合作伙伴的特定需求；（iii）培训高素质人才，以应对我们社会的科学和技术挑战。
