Dredging Solutions - Geotextile Dewatering Tubes

Dewatering

CRS Envitube® dewatering containers provide a unique solution to dewatering many types of fine-grained material, sludges and slurries. With the in-line addition of a suitable polymer the pumped solids combine and release water through the pores in the CRS Envitube® container. 
Due to the surface tension exhibited by full CRS Envitube® containers, rain cannot permeate the geotextile and the contained solids will become progressively drier whilst remaining fully contained. 

All that is required for the placement of the CRS Envitube® units is a level bunded area close to the dredging site ideally allowing the bag filtrate to gravity back to the dam or lagoon.
