oa Civil Engineering = Siviele Ingenieurswese - Construction of the first enhanced barrier system in the world : geotechnical engineering
Geosynthetic materials have been successfully installed as effective barriers in various types of earth and concrete structures over the past 50 years. However, as technology and research in the geosynthetics field evolved, it was found that composite liners have certain limitations, and that heat can significantly decrease the service life of geosynthetic components.
According to the highly respected US Environmental Protection Agency, current standards do not adequately address toxic pollutant discharge, frequently resulting in toxic chemical seepage from unlined ponds and dry waste landfills into ground and surface waters. Although the Agency's concerns refer mainly to pollution caused by coal-related products, the reality is that clean water is the source of life, and hence it is critical to a sustainable future.
