Since 1986, Biobarrier® has been the product of choice for re-directing tree and shrub roots from walls, sidewalks, foundations and landscapes. Biobarrier Root Control System is placed in a trench between roots and the area to be protected and is guaranteed for 15 years. “ When we introduced Biobarrier, it was a different kind of product for the market,” said Jerry Dunaway, Biobarrier sales manager. “It still is unlike anything else. We think it is also the most effective and cost-efficient method of inhibiting root growth. For example, it generally costs about $900 to replace 15 linear feet of 4-foot-wide sidewalk. Using Biobarrier along that same stretch of sidewalk costs less than $50.”

The term "Film Tearing Bond (FTB)" for qualifying welded geomembrane seams essentially disappeared from the waste containment sector several years ago, but it still remains in the potable water sector. Ian Peggs, I-CORP INTERNATIONAL, authors a tech note proposing "that we forever banish FTB."

The Lawrence County Soil and Water Conservation District, Indiana, is giving a tour on December 5 of a farm with heavy use animal traffic zones. Part of the tour will demonstrate the benefits of installing geotextiles in the heaviest traffic spots. Read about it in the Times-Mail. Learn more here.;

Ian Peggs, I-CORP INTERNATIONAL, asks the question "Does geoelectric leak location work?" His answer? "Yes."

Engepol is pleased to announce the addition of their new black and white color geomembrane in our product line. This black and white color geomembrane enables easy and fast damage detection in the site. It was created to attend the client requirements to different applications i.e. storage reservoirs, shrimp farm, aquaculture. The Engepol geomembranes are manufactured from prime high molecular weight resins and were developed to be used under hard chemical and physical conditions in lining of solid waste sites, mines, and any fluid and solid containment applications. Tenemos el gusto de anunciar la introducción de la nuestra geomembrana color blanco y negro en nuestra línea de productos. Esta geomembrana color blanco y negro permite una rápida y facil detección de daños en el sitio. Esto producto fué creado para atender los requirimientos de nuestros clientes para diferentes aplicaciones como por ejemplo reservorios,camaroneras,acuicultura. Las geomembranas Engepol son fabricadas con resinas virgenes y desarolladas para uso en condiciones quimicas y fisicas severas en proyectos de relleno sanitario, minerias e en cualquier aplicacion de contenimiento de fluidos y solidos.

The Environmental News Network (ENN) reports that the world faces less of a water shortage than it does proper water system management. This includes a need to fix leaking pipes and to utilize containment technologies such as barriers for conserving water in canals and reservoirs. Poor management means that 40 to 60 percent of water fails to reach the intended consumers. Learn more here.;

"When asked what voltage setting was used to perform spark testing on a pipe penetration weld the operator said “Dunno, I just turned it to the max as stated in the instructions”! This is just the right way to miss leaks, as happened..." Ian Peggs of I-CORP INTERNATIONAL takes a look at what is occurring during spark testing.

David D'Souza, writing for the Goa, India-based Herald, discusses modern, double-lined landfill design but in plain language. He explains the importance of geosynthetic systems, including drainage and containment, and he does it all with easily understandable comparisons, such as geomembrane liners and bathtubs. His succinctly answered questions and plain language demonstrate one way engineers might better engage the public on critical waste designs. Read the article at the link below. Learn more here.;

Studies from Europe are finding that municipal landfills can safely incorporate debris that has been contaminated by chemical weapons, such as sarin, mustard gas and VX. Questions about burying hazardous debris arose following the terrorist attacks on the World Trade Center in New York, the railways in Spain and London's subway. Researchers found that modern geosynthetic-lined landfills will provide the necessary containment and groundwater protection. Learn more here.;

According to JEC Group, nonwoven geotextiles are expected to be in great demand in India as nearly 10,000 km of coastal roads are planned. Also, significant waterway connection projects are planned for India, which may require or benefit greatly from other geosynthetic stabilization and containment technologies. Learn more here.;

The Trojan Nuclear Power Plant cooling tower in Kalama, Oregon, came down with the aid of 2,792 pounds of dynamite. Geotextile fabric, wrapped around key blast points, contained the spread of concrete debris. It was one the demolition firm's largest and most advanced projects. The demolition details can be found at The Columbian news site. A video link is available too. Learn more here.;

According to Iceland Review, borehole samples in Iceland indicate that gold may be mined there. Studies are on-going as to whether the gold content in the rock is significant enough to justify and pay for the processing. Geosynthetic containment systems have become vital to controlling mining-related pollution while creating efficiencies in the processing system: product is not lost. Learn more here.;

ASCE G-I Geosynthetics committee is soliciting papers for a mini symposium during GeoDenver 07 under the following theme: Geosynthetics in Cyclic, Seismic, and Dynamic Applications: Lesson Learned. If interested , please forward brief abstract (100 words in PDF format) to Mo Gabr, gabr@eos.ncsu.edu by April 17 2006. Geosynthetic materials are used in many difficult geological conditions as a tool for cost effective design and enhanced construction. While applications in various industry sectors are at different stages of development, documented case histories on the use of geosynthetics in cyclic, seismic, and dynamic projects are rare. This mini symposium entitled "Geosynthetics in Cyclic, Seismic, and Dynamic Applications: Lesson Learned" aims to encompass several (may be 2-4) sessions describing lessons learned when incorporating geosynthetics in such applications. The cyclic, seismic, and dynamic cases include machine and traffic, earthquakes, explosives, wave, and impact loading with reinforcement, drainage, and containment application. As such, examples with a focus on design or performance case histories are (loading being cyclic, seismic, and/or dynamic): i. Dams and Liquefaction ii. Seismic Stability of Mining Impoundments ii. Walls and Slopes iii. Water Storage Reservoirs and Waste Containment Facilities iv. Structures subjected to Wave Loading including Shorelines v. Machine Foundation vi. Bridge Foundation vii. Instrumented Pavement Sections viii. Other Applications. Learn more here.;
