Composite layered geotextile having low deformability and high filtering and drainage capability

摘要

A laminated composite geotextile with a good filtering-drainage capacity and an extensibility of at least 50% less than that of conventional geotextiles or known composites having similar tensile strength is produced by the interconnection of at least one layer which is adapted to afford tensile strength and low deformation and a set of two or more layers having good drainage and/or filtering properties.
