Class A and Class B Geotextile Specifications
Class A geotextile is used as a separation layer beneath 1 m of aggregate/rock fill, while Class B geotextile is used as a filtration layer placed beneath dikes. Class A and Class B geotextiles can be woven or non-woven, made of UV-resistant polypropylene or polyester.
Class A and Class B geotextiles must be protected against mechanical damage and chemicals. In addition, the geotextile must not be exposed to sunlight for more than 7 days before being covered.
The classification parameters for Class A and Class B geotextiles are shown in the following table.
