Geotextile Tubes for Environmental Applications

by Chris Lawson (TenCate Geosynthetics Asia-Pacific)


28 April 2022


10:30 am



Geotextile tubes are permeable containment units. They are used for coastal and hydraulic applications and for mining and environmental applications. For environmental applications (the subject of this presentation) geotextile tubes are used to dewater contaminated sediments and industrial slurries where the filtered effluent water is returned to the natural environment or recirculated within the industrial process. The dewatered solids are either left contained insitu or removed to a disposal facility. More commonly, for large scale projects the dewatered solids are left contained insitu within the geotextile tubes. Two detailed case studies are presented where the beneficial re-use of the contained dewatered contaminated sediments were used for non-structural fill (in China) and for structural fill (in Brazil).
