Geotextile tubes are filled by pumping material in slurry form into the tube to form structures that can be used as breakwaters, levees, or other containment structures. TenCate has a new product that much improves what was a weak point in the system, the connection between the geotextile tube and the injection system. Their newly-patented Geoport mechanical injection system reduces stress at the injection point, and makes sure that the final closed connection is as strong as the geotextile itself.

Geosynthetics at De-Icing Facitility
GeoSynthetica was kind enough to track down an interesting case study in the use of geosynthetics at a new de-icing facility at Cleveland’s Hopkins International Airport. Ethylene Glycol and Propylene Glycol are commonly used de-icing chemicals. Most de-icing is done at the gate to avoid flight delays, but it also increases the chance of environmental contamination. In the design of a new dedicated de-icing facility at the airport, geosynthetic clay liners (GCL), Geocells, geotextiles and geocomposites were all used to handle chemical-laden runoff as well as regular runoff during the non-icy times of year. Also there is a problem with high water table and a resulting detrimental effect on the pavement subgrade. This is where the aggregate-filled geocells were used. Read on for the link.
