Description
Geobag Dewatering Bags
Geobag dewatering bags (also called geobags, dewatering tubes) are large, high-strength containers made from permeable geotextile fabrics. They are filled with slurry (e.g., sediment, sludge, or contaminated dredged materials) to separate solids from water through filtration and consolidation. Or filled with sand for coastal protection projects.

PP Woven Geotextile is interwoven by high tenacity PP filament yarn into a dimensionally stable network. The inherent characteristics of Polyesterhigh tensile strength and modulus,low elongation, low creep and high longterm design strength makes the good ideal for soil reinforcement application. The fabric develops excellent frictional interaction with a wide variety of soil and granular materials.
The relatively low openings of these fabrics enable them to act as efficient separators preventing the mixing of costly granular materials with finegrained soils. It has reasonably high permeability to prevent excessive buildup of porepressures due to applied loadings.

Geobag Dewatering
Geobag Dewatering dewatering filling with Environmental Sediments, Industrial Sludge, Sewage, Mining Residuals and etc. There are too many sediments carried by rivers and streams into down gradient harbors, estuaries and deltas every year in the world. The dredging, a safe and efficient strategies is necessary, the geotextile dewatering tube not only to dewater the dredged material while under pressure but also to decontaminate them is the unltimate goal. By dewatering we mean to decrease the water content of slurried material to a point where geotextile bags handling of the sediments by standard earth moving equipment is possible.

Geobag Sludge Dewatering
After the solids have fully solidified or fulfilled the minimal criteria for transportation, the dewatered materials can be disposed of in a variety of ways. Geotube dewatering containers are constructed into tubular, sack like, or other shapes with loading ports or other arrangements for site filling utilizing high resilience and grade seaming processes.

Geotextile Dewatering Tubes
Geotextile Dewatering Tubes are used in a wide range of applications to dewater sediment laden water retaining the soil particles in the tubes allowing the clean water to filter through the tubes. The filtrate water is often returned into the source pond or released depending on the consent conditions.

Nonwoven Geotextile Geobag
Encapsulating or wrapping sand into geotextile units provides a variety of flexible, economical and ecological coastal applications. Especially at sandy beaches, the use of rocks, steel and concrete as "hard coastal structures" should be avoided where possible.Geobag made of needle-punched nonwovens offer more advantages as 'soft rock structures'.as flexible construction elements geobag behave advantageously with respect to cyclical hydrodynamic loads and morphological seabed changes.
