GSI to host webinar on geotextile tubes

Products | June 11, 2018 | By:

The Geosynthetic Institute (GSI) will sponsor a webinar entitled “Applications and Design of Geotextile Tubes,” on Wednesday, June 13, 2018, from 11:30 a.m. to 1 p.m. EDT.

Geotextile tubes are large factory-fabricated textile tubes with multiple access ports for introduction of infilled material, which is usually dredged and in slurry form. After an overview, a nine-part design procedure will be presented that represents the current state of the practice. The webinar will then proceed with details of adding decontamination materials to the slurries to properly handle contaminated river and harbor sediments. Several economic examples will be presented.

Participants will learn the fabric-manufacturing details, including testing, as well as design idiosyncrasies of geotextile tubes. Current extensions into adding deflocculants to reduce “filter cake” formation and neutralizing hazardous constituents of fine-grained sludges will be explained.

This webinar will be useful for federal, state and regional hydraulic, geotechnical and environmental engineers; engineers from municipal districts and townships; private and municipal land developers; general civil consulting engineers; testing laboratories servicing these organizations; manufacturers of geosynthetic materials; contractors and installers of geosynthetic materials; academic and research groups; and others desiring technical information on this important aspect of our hydraulic infrastructure.

The webinar will be taught by Dr. Robert M. Koerner, professor emeritus of civil engineering at Drexel University and director emeritus of the Geosynthetic Institute.

Webinars cost $200.00 for GSI members and $250.00 for nonmembers. Successful completion of a multiple-choice test after the webinar carries 1.5 professional development units.
