Geomembranes are now used in most domains of geotechnical engineering to control advection out of structures, for example water reservoirs, irrigation canals and dams. They also have extensive applications for limiting pollutant migration in solid waste landfills and liquid waste lagoons. Geomembranes are made of polymers such as polyolefins and polyvinylchloride, which display a low permeability to several liquids including water. When installed and tested by a skilled installer, they provide reliable containment and protection of Canada's water resources.

土工膜现在被用于大多数土工工程领域，以控制结构的平流，例如水库，灌溉渠和水坝。它们还广泛应用于限制固体废物填埋场和液体废物泻湖中的污染物迁移。土工膜由聚烯烃和聚氯乙烯等聚合物制成，它们对包括水在内的几种液体的渗透性很低。当由熟练的安装人员安装和测试时，它们为加拿大的水资源提供可靠的密封和保护。
