polypropylene spunbond needle punched geotextiles are applicable for any water conservancy project. It can be used individually as reinforced layer for dams, river/ lake seawalls, or it can also be used as anti-seepage layer by combining with geomembranes. Especially in anti-seepage or cement-reinforced projects, polypropylene spunbond needle punched geotextile is the best choice with the regards that the alkali of cement will dissolve polyester geotextiles within half a year, causing water pollution, engineering failure, and even casualty accidents.
