Scope

1.1 This standard specifies requirements for three types of geobags made from needle punched non-woven fabric of polyester (PES) or polypropylene (PP), used for coastal and waterways protection applications such as revetments; river training; construction of groynes and artificial reefs; etc, in order to minimize soil erosion and control floods.

NOTES

1 The survivability/durability of geobag depends upon water pressure, soil condition, type of contents of geobag that is sand or gravels, water pH and temperature etc.

2 Woven slit film geotextiles, that is, geotextiles made from yarns of a flat, tape-like character, shall not be used for the manufacture of geobags for permanent erosion control applications

1.2 This standard does not apply to other types of geo- synthetic erosion control materials such as turf reinforcement mats.
