Self-Healing Rubber Products?

0
In a blog posted at Daily Tech, Jason Mick writes on how Dr. Anke Nellesen and colleagues at the Fraunhofer Institute for Environmental, Safety and Energy Technology in Germany created an elastomeric material capable of responding to stresses with something of a "self-healing" property. While the process cannot be totally self-controlled--it requires external monitoring and input of ions--it does seems possible to automate it. Perhaps discoveries like this will lead to polymeric olefin and synthetic rubber membranes that can respond to stress before cracking and failure. Learn more here.;

Mining Cleanup Tax

0
In Florida, a higher tax will be placed on phosphate companies to encourage quicker closure of former gypsum operations. Florida has a long successful gypsum mining industry, but its environmental legacy is not nearly as admirable. Significant cleanup and capping are required for operations dating back decades. The Ledger article includes an interesting close-up photo of a geomembrane being seamed. Learn more here.;

Bring Back the Canal Liner?

0
The Kennewick Irrigation District (KID) in Washington State has had a number of seepage issues in its earthen canals this year. The Badger East Canal is currently experiencing significant seepage problems. While the earthen canals are designed for it, the Badger East Canal had a geosynthetic liner for water conservation between 1989 and the middle of this year. Rather than replace the liner, which KID felt had reached the end of its service life, the canal was deepened and packed with a bit of clay. The result has been flooded basements and a need to reapproach the canal's management. Learn more here.;

Urban Design: Separation Geotextiles and Root Barriers

0
The Journal of Environmental Quality's (JEQ) most recent issue includes "Can Urban Tree Roots Improve Infiltration through Compacted Subsoils for Stormwater Management?" The researchers who produced the article examined the effects of root penetrations on water infiltration and examined water detention system using special soil arrangements and geotextile separation fabrics. “Manipulating root penetration through these separation geotextiles could potentially play a large role in bioretention system function and design," says the project lead, Susan Day of Virginia Tech.

Hot Presentation: Geosynthetics and Fiber Optics

0
On Monday, March 14, during the Geo-Frontiers 2011 conference (13-16 March 2011, Dallas), John Lostumbo of TenCate Geosynthetics will present a much-anticipated paper on "Geosynthetic Enabled with Fiber Optic Sensors for MSE Bridge Abutment Supporting Shallow Bridge Foundations." Geotextiles with fiberoptic components provide a resource for monitoring various design functions including strain. Data collected from fiber optic monitoring can be used to determine the functional longevity of civil structures helping to insure safety as well as providing data which may be used for evaluation of design methods.

Experts recommend lining for reservoir

0
Engineers investigating the raw water reservoir in Fremont, Ohio have discovered some karst. Among other effects, karst can cause seepage, piping, and instability. The engineers' report from Arcadis recommend a composite liner system (HDPE or LLDPE geomembrane and GCL) across the entire slope, protected by geotextile and cover soil, and geogrid reinforcement. The city has roughly one year to complete the reservoir project and must now seek approval to alter the design and include a lining system. Learn more here.;
