Containment facilities require multiple geosynthetics, which creates a need to design with a strong understanding of the interface between soils and geosynthetics and between different geosynthetics. The new...

ASTM International Committee D35 on Geosynthetics is currently developing a proposed new standard that covers the test procedure for evaluating the effectiveness of prefabricated vertical drains to enhance the consolidation of soils under specified conditions. The proposed standard, WK13402, Test Method for Large Scale Consolidation Test for Prefabricated Vertical Drains, is under the jurisdiction of Subcommittee D35.03 on Permeability and Filtration. “For geotechnical engineers that are very familiar with sand drains as a means of accelerating consolidation of soft foundation soils, WK13402 will provide a means of evaluating how prefabricated vertical drains perform in relation to a sand drain,” says L. David Suits, a member of the task group developing the standard and executive director, North American Geosynthetics Society. Suits notes that the proposed standard will be most useful to engineers who are designing structures or embankments over soft foundation walls. For further technical information, contact L. David Suits, North American Geosynthetics Society, Albany, N.Y. (phone: 518/869-2917; Nagsdirector@aol.com). Committee D35 will meet June 27-29, 2007, at the June Committee in Norfolk, Va. For membership or meeting information, contact Christine Sierk, manager, Technical Committee Operations, ASTM International (phone: 610/832-9728; csierk@astm.org). Committee D35 is one of 139 ASTM technical standards-writing committees. Established in 1898, ASTM International is one of the largest standards development and delivery systems in the world. ASTM standards are accepted and used in R&D, product testing, quality systems, and commercial transactions around the globe.

Two papers at Geo-Frontiers will review the relationship between containment geosynthetics and the transmission of VOCs. The first paper, "Diffusion of Volatile Organic Compounds through an HDPE Geomembrane," will be presented on Tuesday, March 15, by Nathalie Touze-Foltz of Cemagref. The paper will describe the findings of Cemagref research on this topic. The second paper, "Sorption and Diffusion of BTEX through Thin-Film EVOH," discusses the ability of modified film to block VOC diffusion. This is a timely subject as new geomembrane materials incorporating EVOH have recently been developed, the first of this kind is now being manufactured by Raven Industries. The second paper will be presented on Tuesday, March 15, between 3:00 PM - 4:30 PM in the "Geosynthetic Properties and Evaluation" track. It is authored by Rebecca S. McWatters and R. Kerry Rowe of Queen's University. Learn more here.;

The International Association of Geosynthetic Installers is proud to announce DDT Liners from Queensland, Australia to be the first to achieve the designation of Approved Installation Contractor (AIC) Internationally. Currently, IAGI has awarded the AIC status to seven companies within the United States and Canada. DDT Liners marks the first company to comply with industry standards within the country of Australia to receive the AIC International Australia designation. The Mission of the Approved Installation Contractor program is: To establish criteria for recognizing the geosynthetic installation companies that meet a minimum level of professionalism, experience and business practices. The program’s goal is to promote growth in the geomembrane installation industry and promote better quality workmanship. AIC applicants must meet requirements in the following areas: corporate history and business practices, insurance verification, safety training, and professional competence and experience. Below is a list of information required on the AIC submittal form: Company history and information; Minimum 500,000 square feet installed annually; Ability to be bonded (or for international cases where bonding is not applicable, a letter from the bank president the company currently has a relationship with); General liability insurance; Worker Compensation insurance; Automobile liability; Safety training; Health and safety orientation program; Drug-free work program; Professional competence/experience; 15% of their installation crews are Certified Welding Technicians (CWT) required (CWT is an official IAGI certification program for welders.) All of the above information is reviewed and verified by IAGI’s third party reviewer. Applicants also must submit for verification written references from the following industry professionals: engineers; contractors/owners; and geosynthetic manufacturers. Each of the items submitted are reviewed and verified by the third party. This entire process must be repeated annually. IAGI strives to provide a forum for geosynthetics installers to advance installation and construction techniques, and to strengthen the knowledge, image and communication within the industry.
