Geomembrane, widely used in canal seepage control project. In recent years, geosynthetics in civil engineering, in particular, a large number of applications and their effectiveness in flood rescue project, causing the majority of engineering and technical staff are highly valued. For geosynthetics technology, the country from seepage, filtration, drainage, reinforcement, protection and other aspects of proposed normative technical requirements, greatly accelerated the pace of the popularization and application of new materials. The material is widely used in the irrigation canal seepage project, combined with the construction practice of geomembrane application technology.
